This document is in two parts. The first part is this prospectus supplement, which describes the terms of this offering of common stock and also adds to and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part, the accompanying prospectus dated November 16, 2017, including the documents incorporated by reference therein, provides more general information. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. To the extent there is a conflict between the information contained in this prospectus supplement, on the one hand, and the information contained in the accompanying prospectus or in any document incorporated by reference that was filed with the SEC before the date of this prospectus supplement, on the other hand, you should rely on the information in this prospectus supplement. If any statement in one of these documents is inconsistent with a statement in another document having a later date (for example, a document incorporated by reference in this prospectus supplement) the statement in the document having the later date modifies or supersedes the earlier statement.

We are responsible for the information contained in or incorporated by reference to this prospectus supplement, the accompanying prospectus or any free writing prospectus prepared by or on behalf of us. Neither we nor the selling stockholder have authorized anyone to provide you with additional or different information. We, and the selling stockholder, take no responsibility for, and can provide no assurances as to the reliability of, additional, different or inconsistent information that others may give you. If you are in a jurisdiction where offers to sell, or solicitations of offers to purchase, shares of our common stock are unlawful, or if you are a person to whom it is unlawful to direct these types of activities, then the offer presented in this document does not extend to you. You should assume the information appearing in this prospectus supplement, the accompanying prospectus or any free writing prospectus is accurate only as of the respective dates of such information.

Our stock price may fluctuate significantly following the offering, and you may not be able to resell shares of our common stock at or above the price you paid or at all, and you could lose all or part of your investment as a result.

The trading price of our common stock may experience volatility following this offering. Market volatility often has been unrelated or disproportionate to the operating performance of particular companies. You may not be able to resell your shares at or above the public offering price due to a number of factors such as those listed in "—Risks Related to Our Business" and the following:

These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our common stock is low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we were involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

All statements other than statements of historical facts in this document, including, without limitation, those regarding our business strategy, financial position, results of operations, plans, prospects and objectives of management for future operations (including development plans and objectives relating to our activities), are forward-looking statements. Many, but not all, of these statements can be found by looking for words like "expect," "anticipate," "goal," "project," "plan," "believe," "seek," "will," "may," "forecast," "estimate," "intend" and "future" and similar words. Statements that address activities, events or developments that we intend, expect or believe may occur in the future are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and section 21E of the Exchange Act and are subject to safe harbor created by those sections. Forward-looking statements do not guarantee future performance and may involve risks, uncertainties and other factors which could cause our actual results, performance or achievements to differ materially from the future results, performance or achievements expressed or implied in those forward-looking statements.

Examples of these risks, uncertainties and other factors include, but are not limited to:

There may be other factors, many of which are beyond our control, that may cause our actual results to differ materially from the forward-looking statements, including factors disclosed under the sections entitled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2017 Form 10-K and our 2018 Q1 Form 10-Q.

The forward-looking statements contained in this prospectus supplement and the accompanying prospectus speak only as of the date of this prospectus supplement and the accompanying prospectus supplement respectively. Such forward looking statements are based on our current beliefs, assumptions, expectations, estimates and projections regarding our present and future business strategies and the environment in which we will operate in the future. We undertake no obligation to publicly release the result of any revisions to these forward-looking statements, to reflect events or circumstances after the date of this prospectus supplement or the accompanying prospectus supplement or to reflect the occurrence of unanticipated events.

We will not receive any of the proceeds from the sale of shares of our common stock by the selling stockholder. The selling stockholder will receive all of the proceeds from this offering.

This prospectus supplement relates to the resale of up to a total of 11,987,453 shares of common stock by the selling stockholder. On October 12, 2016, we entered into a registration rights agreement with the selling stockholder pursuant to which we agreed to prepare and file a registration statement to permit the resale of the shares covered by this prospectus supplement. The selling stockholder identified below may currently hold or acquire at any time shares of common stock in addition to those registered hereby.

Beneficial ownership for the purposes of the following table is determined in accordance with the rules and regulations of the SEC. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting thereof, or to dispose or direct the disposition thereof or has the right to acquire such powers within 60 days. Except as disclosed in the footnotes to the table below and subject to applicable community property laws, we believe that each stockholder identified in the table possesses sole voting and investment power over all shares of common stock shown as beneficially owned by the stockholder.

Our calculation of the beneficial ownership in the following table is based on 88,554,586 shares of our common stock outstanding as of May 3, 2018.

(1): Star Atlantic GP Inc. ("Star Atlantic GP") was the general partner, and Star Atlantic Waste Holdings, L.P. ("Star Atlantic") was a limited partner, of Star Atlantic Waste Holdings II, L.P. ("Star Atlantic II"), which held shares in Advanced Disposal Waste Holdings Corp., our former parent company prior to our initial public offering. On October 12, 2016, our former parent company, which owned all of our outstanding common stock prior to the initial public offering, was merged with and into us, with the Company as the surviving corporation. In the merger, all of our issued and outstanding shares of common stock held by our former parent company were canceled, and pre-merger holders of the capital stock of our parent company received shares of our Common Stock. Immediately after our initial public offering, Star Atlantic II distributed to Star Atlantic 41,985,997 shares of our Common Stock that it received in the merger. PineBridge Highstar (SPE) LLC serves as the general partner of Star Atlantic GP and has delegated management authority for Star Atlantic GP to Highstar Capital LP ("Highstar Capital"). Highstar Capital is a registered investment adviser. Highstar Capital also serves as the investment manager for Star Atlantic. Star Atlantic is the direct holder of the shares of Common Stock reported in the table above. The principal business address of each of the entities and persons identified in this and the paragraph above is Highstar Capital, 277 Park Avenue, 45th floor, New York, New York 10172.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS OF OUR
COMMON STOCK

The following is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) associated with the purchase, ownership and disposition of our common stock, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations promulgated thereunder ("Treasury Regulations"), administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed, possibly retroactively, and any changes may result in U.S. federal income tax consequences different from those set forth below. We have not sought any ruling from the Internal Revenue Service (the "IRS") with respect to the statements made and the conclusions reached in the following summary. The authorities on which this discussion is based are subject to various interpretations and there can be no assurance that the IRS or the courts will agree with such statements and conclusions.

This summary also does not address the tax considerations arising under the laws of any state, local or non-U.S. jurisdiction or under U.S. federal gift and estate tax laws, the alternative minimum tax or the Medicare tax on net investment income. This summary is limited to Non-U.S. Holders who hold our common stock as a capital asset for U.S. federal income tax purposes (generally, property held for investment). In addition, because this section is a general summary, it does not address all aspects of taxation that may be relevant to particular shareholders in light of their personal investment or tax circumstances, or to certain types of shareholders that are subject to special treatment under the U.S. federal income tax laws, including, without limitation, brokers or dealers in securities, insurance companies, banks or other financial institutions, hybrid entities, regulated investment companies, real estate investment trusts, tax-exempt organizations or accounts, persons holding common stock as a part of a hedging, integrated, conversion transaction, straddle or other risk reduction transaction, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, entities or arrangements treated as partnerships for U.S. federal income tax purposes or investors in such entities, persons who acquired our common stock through the exercise of employee stock options or otherwise as compensation for services, certain former U.S. citizens or long-term residents, "controlled foreign corporations" or "passive foreign investment companies" within the meaning of the Code, and persons deemed to sell our common stock under the constructive sale provisions of the Code.

Non-U.S. Holders are urged to consult their tax advisors with respect to the application of the U.S. federal income tax laws to their particular situations, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. federal estate or gift tax rules or under the laws of any state, local, non-U.S. or other taxing jurisdiction or under any applicable tax treaty.

As used in this discussion, the term "Non-U.S. Holder" means a beneficial owner of our common stock that, for U.S. federal income tax purposes, is an individual, corporation, estate or trust and is not any of the following for U.S. federal income tax purposes:

We do not anticipate making distributions on our common stock in the foreseeable future. However, if distributions of cash or property (other than certain pro rata stock distributions) are made to Non-U.S. Holders on shares of our common stock, such distributions generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce a Non-U.S. Holder's basis in our common stock (determined separately with respect to each share of our common stock), but not below zero, and then will be treated as gain from the sale of that common stock as described below under "—Gain on Disposition of Our Common Stock."

Except as described in the next paragraph and subject to the discussions of backup withholding and FATCA, any dividend paid to a Non-U.S. Holder generally will be subject to U.S. federal withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. In order to receive a reduced treaty rate, the Non-U.S. Holder must provide the applicable withholding agent in a timely manner a properly completed IRS Form W-8BEN or W-8BEN-E, whichever is applicable, or other appropriate version of IRS Form W-8, including a U.S. taxpayer identification number and certifying qualification for the reduced rate. A Non-U.S. Holder of shares of our common stock eligible for a reduced rate of U.S. federal withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS in a timely manner. If the Non-U.S. Holder holds the common stock through a financial institution or other agent acting on the Non-U.S. Holder's behalf, the Non-U.S. Holder will be required to provide appropriate documentation to the agent, which then will be required to provide certification to the applicable withholding agent, either directly or through other intermediaries.

Dividends received by a Non-U.S. Holder that are effectively connected with its conduct of a U.S. trade or business (and, if an income tax treaty requires, that are attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), are exempt from such withholding tax. In order to claim this exemption, the Non-U.S. Holder must provide the applicable withholding agent with a properly completed IRS Form W-8ECI or other applicable IRS Form W-8 properly certifying such exemption. Such effectively connected dividends, although not subject to U.S. federal withholding tax, generally are subject to U.S. federal income tax on a net income basis at applicable graduated U.S. federal income tax rates, net of certain deductions and credits, and generally in a manner applicable to U.S. persons. In addition, dividends received by a Non-U.S. Holder that is treated as a corporation for U.S. federal income tax purposes that are effectively connected with such Non-U.S. Holder's conduct of a U.S. trade or business may also, subject to certain adjustments, be subject to a branch profits tax at a rate of 30% or such lower rate as may be specified by an applicable income tax treaty.

Subject to the discussions of backup withholding and FATCA, Non-U.S. Holders generally will not be required to pay U.S. federal income tax, including by way of withholding, on any gain realized upon the sale or other disposition of our common stock unless:

Generally, a corporation is a USRPHC if the fair market value of its U.S. real property interests (within the meaning of the Code and applicable Treasury Regulations) equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests plus its other assets used or held for use in a trade or business. We believe that we are not currently a USRPHC and, based on our business plan and anticipated operations, do not expect to become a USRPHC in the future. However USRPHC status is an inherently factual determination that involves complex legal considerations. We have not sought an IRS ruling with respect to whether we are a USRPHC and we cannot give definitive assurance regarding our non-USRPHC status. Additionally, because the determination of whether we are a USRPHC depends on the fair market value of our U.S. real property interests relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we are or become a USRPHC, as long as our common stock is regularly traded on an established securities market (within the meaning of the Code and applicable Treasury Regulations), such common stock will be treated as a U.S. real property interest only if a Non-U.S. Holder actually or constructively holds more than 5% of such regularly traded common stock at any time during the shorter of the five-year period preceding the Non-U.S. Holder's disposition of, or the Non-U.S. Holder's holding period for, our common stock. Non-U.S. Holders should be aware that no prediction can be made as to whether our common stock will be regularly traded on an established securities market (within the meaning of the Code and applicable Treasury Regulations).

Non-U.S. Holders described in the first bullet above will be required to pay tax on the net gain derived from the sale under regular graduated U.S. federal income tax rates, and a corporate Non-U.S. Holder described in the first bullet above also may be subject to the branch profits tax at a 30% rate, or such lower rate as may be specified by an applicable income tax treaty. Individual Non-U.S. Holders described in the second bullet above will be required to pay a flat 30% tax on the gain derived from the sale, which gain may be offset by certain U.S.-source capital losses, provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses. Non-U.S. Holders should consult any applicable income tax or other treaties that may provide for different rules.

Generally, we must report annually to the IRS the amount of dividends paid to a Non-U.S. Holder, the Non-U.S. Holder's name and address, and the amount of U.S. federal income tax withheld, if any. A similar report will be sent to the Non-U.S. Holder. These information reporting requirements apply even if withholding was not required because the dividends were effectively connected to the conduct of a Non-U.S. Holder's trade or business within the United States or withholding was reduced

or eliminated by an applicable income tax treaty. Pursuant to applicable income tax treaties or other agreements, the IRS may make these reports available to tax authorities in the Non-U.S. Holder's country of residence.

Payments of dividends on, or of proceeds from the disposition of, our common stock made to Non-U.S. Holders may be subject to additional information reporting and backup withholding unless the Non-U.S. Holder establishes an exemption, for example, by properly certifying its non-U.S. status on an IRS Form W-8BEN or W-8BEN-E, whichever is applicable, or another appropriate version of IRS Form W-8. Notwithstanding the foregoing, backup withholding and information reporting may apply if the applicable withholding agent has actual knowledge, or reason to know, that a holder claiming to be a Non-U.S. Holder is a U.S. person.

U.S. information reporting and backup withholding generally will not apply to a payment of proceeds of a disposition of common stock where the transaction is effected outside the United States through a non-U.S. office of a non-U.S. broker. However, information reporting requirements, but not backup withholding, generally will apply to such a payment if the broker is (i) a U.S. person; or (ii) a foreign person with certain U.S. connections, unless the broker has documentary evidence in its records that the holder is a Non-U.S. Holder and certain conditions are met or the holder otherwise establishes an exemption.

Backup withholding is not an additional tax; rather, the U.S. federal income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund or credit may generally be obtained from the IRS, provided that the required information is furnished to the IRS in a timely manner. Non-U.S. Holders should consult their own tax advisors regarding the application of backup withholding in their particular circumstances and the availability of and procedure for obtaining an exemption from backup withholding under current Treasury Regulations.

Legislation commonly known as FATCA (under Sections 1471 to 1474 of the Code) generally imposes a U.S. federal withholding tax of 30% on dividends on and the gross proceeds of a disposition of our common stock paid to a "foreign financial institution" (as defined under FATCA and the applicable Treasury Regulations), unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding the U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise establishes an exemption. FATCA also generally imposes a U.S. federal withholding tax of 30% on dividends on and the gross proceeds of a disposition of our common stock paid to a non-financial foreign entity unless such entity provides the applicable withholding agent with a certification identifying certain substantial direct and indirect U.S. owners of the entity, certifies that there are none or otherwise establishes an exemption. The withholding taxes described above apply currently to any dividend payments on our common stock and will apply after December 31, 2018, to payments of gross proceeds from dispositions of our common stock. Under certain circumstances, a Non-U.S. Holder might be eligible for refunds or credits of such taxes. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this paragraph. Prospective investors are urged to consult with their own tax advisors regarding the possible implications of this legislation on their investment in our common stock.

Credit Suisse Securities (USA) LLC and UBS Securities LLC are acting as underwriters of the offering. Subject to the terms and conditions set forth in an underwriting agreement between us, the selling stockholder and the underwriters, the selling stockholder has agreed to sell to the underwriters, and the underwriters have agreed to purchase from the selling stockholder, the respective number of shares of common stock opposite its name below:

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The underwriters are purchasing the shares of common stock from the selling stockholder at $22.45 per share (representing $269,118,319.85 aggregate proceeds to the selling stockholder, before expenses). The underwriters may offer the shares of common stock from time to time for sale in one or more transactions on the NYSE, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. In connection with the sale of the shares of common stock offered hereby, the underwriters may be deemed to have received compensation in the form of underwriting discounts. The underwriters may effect such transactions by selling shares of common stock to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal.

We estimate that the total expenses of the offering payable by us will be approximately $225,000. We have also agreed to reimburse the underwriters for certain of their expenses in an amount up to $25,000.

We, certain of our executive officers and directors, and the holders of more than 5% of our capital stock are expected to enter into lock-up agreements with the underwriters. Under the lock-up agreements, subject to certain exceptions, we and each of these persons may not, without the prior written approval of the underwriters, offer, sell, contract to sell, pledge, or otherwise dispose of, directly or indirectly, or hedge our common stock or securities convertible into or exchangeable or exercisable for our common stock. These restrictions will be in effect for a period ending on and including the date that is 30 days after the date of this prospectus.

The underwriters may, at any time and in their sole discretion, release some or all the securities from these lock-up agreements. If the restrictions under the lock-up agreements are waived, shares of

our common stock may become available for resale into the market, subject to applicable law, which could reduce the market price of our common stock.

We and the selling stockholder agreed to indemnify the underwriters against certain liabilities, including certain liabilities under the Securities Act. If we and the selling stockholder are unable to provide this indemnification, we and the selling stockholder have agreed to contribute to payments the underwriters may be required to make in respect of those liabilities.

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than it is required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. "Naked" short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters' purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.

None of us, the selling stockholder or the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we, the selling stockholder nor the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

In connection with this offering, the underwriters may engage in passive market making transactions in the common stock on the NYSE in accordance with Regulation M under the Exchange Act during a period before the commencement of offers or sales of common stock and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker's bid, that bid must then be lowered when specified purchase limits are exceeded. Passive market making may cause the price of our common stock to be higher than the price that otherwise would exist in the open market in the absence of those transactions. The underwriters are not required to engage in passive market making and may end passive market making activities at any time.

A prospectus in electronic format may be made available on the Internet sites or through other online services maintained by the underwriters in this offering, or by their affiliates. In those cases, prospective investors may view offering terms online and, depending upon the particular underwriter, prospective investors may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares for sale to online brokerage account holders.

Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations. Other than the prospectus in electronic format, the information on any underwriter's website and any information contained in any other website maintained by the underwriters is not part of this prospectus supplement or the accompanying prospectus, has not been approved and/or endorsed by us or any underwriter in its capacity as underwriter and should not be relied upon by investors.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and their respective affiliates may from time to time in the future engage with us and perform services for us or in the ordinary course of their business for which they will receive customary fees and expenses. In the ordinary course of their various business activities, the underwriters and their respective respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of us. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of these securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in these securities and instruments.

In relation to each member state of the European Economic Area, no offer of ordinary shares which are the subject of the offering has been, or will be made to the public in that Member State, other than under the following exemptions under the Prospectus Directive:

provided that no such offer of ordinary shares referred to in (a) to (c) above shall result in a requirement for the Company or any Representative to publish a prospectus pursuant to Article 3 of the Prospectus Directive, or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

Each person located in a Member State to whom any offer of ordinary shares is made or who receives any communication in respect of an offer of ordinary shares, or who initially acquires any ordinary shares will be deemed to have represented, warranted, acknowledged and agreed to and with each Representative and the Company that (1) it is a "qualified investor" within the meaning of the

law in that Member State implementing Article 2(1)(e) of the Prospectus Directive; and (2) in the case of any ordinary shares acquired by it as a financial intermediary as that term is used in Article 3(2) of the Prospectus Directive, the ordinary shares acquired by it in the offer have not been acquired on behalf of, nor have they been acquired with a view to their offer or resale to, persons in any Member State other than qualified investors, as that term is defined in the Prospectus Directive, or in circumstances in which the prior consent of the Representatives has been given to the offer or resale; or where ordinary shares have been acquired by it on behalf of persons in any Member State other than qualified investors, the offer of those ordinary shares to it is not treated under the Prospectus Directive as having been made to such persons. The Company, our representatives and their respective affiliates will rely upon the truth and accuracy of the foregoing representations, acknowledgments and agreements.

This prospectus supplement has been prepared on the basis that any offer of shares in any Member State will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of shares. Accordingly any person making or intending to make an offer in that Member State of shares which are the subject of the offering contemplated in this prospectus supplement may only do so in circumstances in which no obligation arises for the Company or any of the Representatives to publish a prospectus pursuant to Article 3 of the Prospectus Directive in relation to such offer. Neither the Company nor the Representatives have authorized, nor do they authorize, the making of any offer of shares in circumstances in which an obligation arises for the Company or the Representatives to publish a prospectus for such offer.

For the purposes of this provision, the expression an "offer of ordinary shares to the public" in relation to any ordinary shares in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the ordinary shares to be offered so as to enable an investor to decide to purchase or subscribe the ordinary shares, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression "Prospectus Directive" means Directive 2003/71/EC (as amended) and includes any relevant implementing measure in each Member State.

In the United Kingdom, this prospectus supplement is only being distributed to and is only directed at: qualified investors (as defined in the Prospectus Directive) (i) who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (as amended), or the Order; and/or (ii) who are high net worth companies falling within Article 49(2)(a) to (d) of the Order, or (iii) is any other person to whom it may otherwise be lawfully communicated, all such persons together being referred to as relevant persons. The shares are only available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire such shares will be engaged in only with, relevant persons. Any person who is not a relevant person should not act or rely on this prospectus or any of its contents.

This document constitutes an "exempt offering document" as defined in and for the purposes of applicable Canadian securities laws. No prospectus has been filed with any securities commission or similar regulatory authority in Canada in connection with the offer and sale of the shares. No securities commission or similar regulatory authority in Canada has reviewed or in any way passed upon this document or on the merits of the shares and any representation to the contrary is an offence.

Canadian investors are advised that this document has been prepared in reliance on section 3A.3 of National Instrument 33-105 Underwriting Conflicts, or NI 33-105. Pursuant to section 3A.3 of NI 33-105, we and the underwriters are not required to provide investors with certain conflicts of

interest disclosure pertaining to "connected issuer" and/or "related issuer" relationships that may exist between the company and the underwriters as would otherwise be required pursuant to subsection 2.1(1) of NI 33-105.

The offer and sale of the shares in Canada is being made on a private placement basis only and is exempt from the requirement that we prepare and file a prospectus under applicable Canadian securities laws. Any resale of shares acquired by a Canadian investor in this offering must be made in accordance with applicable Canadian securities laws, which may vary depending on the relevant jurisdiction, and which may require resales to be made in accordance with Canadian prospectus requirements, a statutory exemption from the prospectus requirements, in a transaction exempt from the prospectus requirements or otherwise under a discretionary exemption from the prospectus requirements granted by the applicable local Canadian securities regulatory authority. These resale restrictions may under certain circumstances apply to resales of the shares outside of Canada.

Each Canadian investor who purchases the shares will be deemed to have represented to us, the underwriters and to each dealer from whom a purchase confirmation is received, as applicable, that the investor (i) is purchasing as principal, or is deemed to be purchasing as principal in accordance with applicable Canadian securities laws; (ii) is an "accredited investor" as such term is defined in section 1.1 of National Instrument 45-106 Prospectus Exemptions, or NI 45-106, or, in Ontario, as such term is defined in section 73.3(1) of the Securities Act (Ontario); and (iii) is a "permitted client" as such term is defined in section 1.1 of National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations.

Any discussion of taxation and related matters contained in this document does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a Canadian investor when deciding to purchase the shares and, in particular, does not address any Canadian tax considerations. No representation or warranty is hereby made as to the tax consequences to a resident, or deemed resident, of Canada of an investment in the shares or with respect to the eligibility of the shares for investment by such investor under relevant Canadian federal and provincial legislation and regulations.

Securities legislation in certain of the Canadian jurisdictions provides certain purchasers of securities pursuant to an offering memorandum, including where the distribution involves an "eligible foreign security" as such term is defined in Ontario Securities Commission Rule 45-501 Ontario Prospectus and Registration Exemptions and in Multilateral Instrument 45-107 Listing Representation and Statutory Rights of Action Disclosure Exemptions, as applicable, with a remedy for damages or rescission, or both, in addition to any other rights they may have at law, where the offering memorandum, or other offering document that constitutes an offering memorandum, and any amendment thereto, contains a "misrepresentation" as defined under applicable Canadian securities laws. These remedies, or notice with respect to these remedies, must be exercised or delivered, as the case may be, by the purchaser within the time limits prescribed under, and are subject to limitations and defences under, applicable Canadian securities legislation. In addition, these remedies are in addition to and without derogation from any other right or remedy available at law to the investor.

Upon receipt of this document, each Canadian investor hereby confirms that it has expressly requested that all documents evidencing or relating in any way to the sale of the securities described herein (including for greater certainty any purchase confirmation or any notice) be drawn up in the English language only. Par la réception de ce document, chaque investisseur canadien confirme par les présentes qu'il a expressément exigé que tous les documents faisant foi ou se rapportant de quelque manière que ce soit à la vente des valeurs mobilières décrites aux présentes (incluant, pour plus de certitude, toute confirmation d'achat ou tout avis) soient rédigés en anglais seulement.

This prospectus contains and incorporates by reference "forward-looking statements" within the meaning of the U.S. federal securities laws. All statements other than statements of historical facts in this document, including, without limitation, those regarding our business strategy, financial position, results of operations, plans, prospects and objectives of management for future operations (including development plans and objectives relating to our activities), are forward-looking statements. Many, but not all, of these statements can be found by looking for words like "expect," "anticipate," "goal," "project," "plan," "believe," "seek," "will," "may," "forecast," "estimate," "intend" and "future" and similar words. Statements that address activities, events or developments that we intend, expect or believe may occur in the future are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and section 21E of the Exchange Act. Forward-looking statements do not guarantee future performance and may involve risks, uncertainties and other factors which could cause our actual results, performance or achievements to differ materially from the future results, performance or achievements expressed or implied in those forward-looking statements.

Examples of these risks, uncertainties and other factors include, but are not limited to:

There may be other factors, many of which are beyond our control, that may cause our actual results to differ materially from the forward-looking statements, including factors disclosed under the sections entitled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2016 Form 10-K, our 2017 Q1 Form 10-Q, our 2017 Q2 Form 10-Q and our 2017 Q3 Form 10-Q. You should evaluate all forward-looking statements made in this prospectus in the context of these risks and uncertainties.

The forward-looking statements contained in this prospectus speak only as of the date of this prospectus. We undertake no obligation to publicly release the result of any revisions to these forward-looking statements, to reflect events or circumstances after the date of this prospectus or to reflect the occurrence of unanticipated events.

In the case of a sale of shares of our common stock by us, the use of proceeds will be specified in the applicable prospectus supplement. In the case of a sale of shares of our common stock by any selling stockholders, we will not receive any of the proceeds from such sale.

Information about the selling stockholders will be set forth in a prospectus supplement, in a post-effective amendment to the registration statement of which this prospectus forms a part or in filings we make with the SEC under the Exchange Act, that are incorporated by reference herein.

The following is a description of the material terms and provisions of our capital stock, our certificate of incorporation and bylaws, and other rights of holders of our capital stock, including our Stockholders Agreement (as defined herein) as currently in effect. This description is not complete and may not contain all the information you should consider before investing in our capital stock. For more complete information, you should read our certificate of incorporation, bylaws, and the Stockholders Agreement, copies of which are incorporated by reference herein.

Our authorized capital stock consists of 1,000,000,000 shares of common stock, par value $0.01 per share, and 100,000,000 shares of preferred stock, par value $0.01 per share.

Holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors. There will be no cumulative voting in the election of directors, which means that holders of a majority of the outstanding shares of common stock will be able to elect all of the directors, and holders of less than a majority of such shares will be unable to elect any director.

Under our certificate of incorporation, subject to preferences that may be applicable to any outstanding shares of preferred stock, holders of common stock are entitled to receive such dividends, if any, as may be declared from time to time by our board of directors out of funds legally available for dividend payments. Our senior secured credit facilities and the indenture governing our 5.625% senior notes due 2024 impose restrictions on our ability to declare dividends on our common stock.

The holders of common stock have no preferences or rights of conversion, exchange, pre-emption or other subscription rights. In the event that we grant any preemptive rights with respect to our common stock to any person, Highstar Capital, BTG, and CPPIB, and their affiliates, as applicable, so long as they have the right to nominate a designee to our board, shall be entitled to preemptive rights no less favorable than those granted to such person.

There are no redemption or sinking fund provisions applicable to the common stock.

In the event of any liquidation, dissolution or winding-up of our affairs, holders of common stock will be entitled to our assets that are remaining after payment or provision for payment of all of our debts and obligations and after liquidation payments to holders of outstanding shares of preferred stock, if any.

There are 100,000,000 shares of authorized preferred stock which, if issued, would have priority over the common stock with respect to dividends and other distributions, including the distribution of

our assets upon liquidation. Unless required by law or by the NYSE, our board of directors will have the authority without further stockholder authorization to issue from time to time shares of preferred stock in one or more series and to fix the terms, limitations, relative rights and preferences and variations of each series. No shares of preferred stock are issued or outstanding as of the date of this prospectus.

Our certificate of incorporation and bylaws contain provisions indemnifying our directors and officers to the fullest extent permitted by law. We have entered into indemnification agreements with each of our directors which, in some cases, are broader than the specific indemnification provisions contained under Delaware law.

In addition, as permitted by Delaware law, our certificate of incorporation provides that no director will be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director. The effect of this provision is to restrict our rights and the rights of our stockholders in derivative suits to recover monetary damages against a director for breach of fiduciary duty as a director, except that a director will be personally liable for:

This provision does not affect a director's liability under the federal securities laws.

To the extent our directors, officers and controlling persons are indemnified under the provisions contained in our certificate of incorporation, our bylaws, Delaware law or contractual arrangements against liabilities arising under the Securities Act, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The Delaware General Corporation Law (the "DGCL") permits corporations to adopt provisions that renounce any interest or expectancy in, or any offer of an opportunity to participate in, specified business opportunities that are presented to the corporation or one or more of its officers, directors or stockholders. In recognition that our directors and officers may serve as (i) directors, officers and/or employees of Highstar Capital, BTG or CPPIB and their respective affiliates or (ii) as directors, officers and/or employees of other businesses engaged in designing, developing, providing services to, managing, owning or investing in waste management companies ("Dual Role Persons"), our certificate of incorporation provides for the allocation of certain corporate opportunities between us and the Dual Role Persons. Specifically, none of the Dual Role Persons will have any duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business that we do. In the event that a Dual Role Person acquires knowledge of a potential transaction or matter outside of his or her capacity as a director of Advanced Disposal which may be a corporate opportunity, we will not have any expectancy in such corporate opportunity, and the Dual Role Person will not have any duty to present such corporate opportunity to us and may pursue or acquire such corporate opportunity for himself/herself or direct such opportunity to another person. A corporate opportunity that a Dual Role Person acquires knowledge of will not belong to us unless the corporate opportunity at issue is

expressly offered to such person solely in his or her capacity as a director or officer of ours. In addition, even if a business opportunity is presented to a Dual Role Person, the following corporate opportunities will not belong to us: (1) those we are not financially able, contractually permitted or legally able to undertake; (2) those not in our line of business; (3) those of no practical advantage to us; and (4) those in which we have no interest or reasonable expectancy.

In addition to the voting rights that Highstar Capital and its affiliates will have upon completion of this offering as a result of its ownership of our common stock, some provisions of Delaware law contain, and our certificate of incorporation and our bylaws described below contain, a number of provisions which may have the effect of encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our board of directors rather than pursue non-negotiated takeover attempts, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, these provisions will also give our board of directors the power to discourage acquisitions that some stockholders may favor.

We are governed by the provisions of Section 203 of the DGCL regulating corporate takeovers. This section prevents some Delaware corporations from engaging, under some circumstances, in a business combination, which includes a merger or sale of at least 10% of the corporation's assets with any interested stockholder, meaning a stockholder who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of the corporation's outstanding voting stock, unless:

A Delaware corporation may "opt out" of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from a stockholders' amendment approved by at least a majority of the outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be discouraged or prevented.

Our certificate of incorporation and our bylaws include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our company, including the following:

In connection with our initial public offering, we entered into a stockholders agreement (the "Stockholders Agreement") with Highstar Capital, CPPIB and BTG. This agreement grants Highstar Capital the right to nominate to our board of directors a number of designees equal to: (i) at least a

majority of the total number of directors comprising our board of directors, at such time, as long as Highstar Capital and its affiliates beneficially own at least 50% of the shares of our common stock; (ii) at least 40% of the total number of directors comprising our board of directors at such time as long as Highstar Capital and its affiliates beneficially own at least 40% but less than 50% of the shares of our common stock; (iii) at least 30% of the total number of directors comprising our board of directors at such time as long as Highstar Capital and its affiliates beneficially own at least 30% but less than 40% of the shares of our common stock; (iv) at least 20% of the total number of directors comprising our board of directors at such time as long as Highstar Capital and its affiliates beneficially own at least 20% but less 30% of the shares of our common stock; and (v) at least 10% of the total number of directors comprising our board of directors at such time as long as Highstar Capital and its affiliates beneficially own at least 5% but less than 20% of the shares of our common stock. For purposes of calculating the number of directors that Highstar Capital is entitled to nominate pursuant to the formula outlined above, any fractional amounts would be rounded up to the nearest whole number (e.g., one and one quarter directors shall equate to two directors) and the calculation would be made on a pro forma basis after taking into account any increase in the size of our board of directors.

This agreement also grants to each of CPPIB and BTG the right to nominate to our Board of Directors one designee, as long as CPPIB, and its affiliates, or BTG, and its affiliates, as applicable collectively beneficially own at least 5% of the outstanding shares of our common stock.

In addition, in the event a vacancy on the board of directors is caused by the death, retirement or resignation of a Highstar Capital, CPPIB or BTG director-designee, Highstar Capital, CPPIB or BTG, or their affiliates, as applicable, to the fullest extent permitted by law, have the right to have the vacancy filled by a new director-designee of Highstar Capital, CPPIB or BTG, as applicable.

The transfer agent and registrar for our common stock is Wells Fargo Bank, National Association.

We or any selling stockholders may sell the shares directly to purchasers or to or through broker-dealers or agents in one or more transactions at any time at fixed prices, at market prices prevailing at the time of sale, at varying prices determined at the time of sale or at negotiated prices. Such sales may be effected in transactions on any national securities exchange or quotation service on which the shares may be listed or quoted at the time of sale, in the over-the-counter market or in transactions other than on such exchanges or services or in the over-the-counter market. We or any selling stockholders may use any one or more of the following methods when selling shares:

We or any selling stockholders may enter into hedging transactions from time to time in which a selling stockholder may:

We or any selling stockholders may also sell shares under Rule 144 of the Securities Act, if available, rather than under this prospectus.

We or any selling stockholders and any broker-dealers or agents that are involved in selling the shares may be deemed to be "underwriters" within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Any selling stockholder who is an "underwriter" within the meaning of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act and the provisions of the Exchange Act and the rules thereunder relating to stock manipulation. In order to comply with certain states' securities laws, if applicable, the shares sold in those jurisdictions may only be sold through registered or licensed brokers or dealers.

The selling stockholders have informed us that none of them has any agreement or understanding, directly or indirectly, with any person to distribute the shares offered by this prospectus. If any selling stockholder notifies us that a material arrangement has been entered into with a broker-dealer for the sale of shares through a block trade, special offering or secondary distribution or a purchase by a

broker or dealer, we may be required to file a supplement to this prospectus pursuant to the applicable rules promulgated under the Securities Act.

There can be no assurance that any selling stockholder will sell any or all of the shares of common stock covered by this prospectus.

We are required to pay all fees and expenses incident to the registration of the shares. We or any selling stockholders will bear the fees, discounts, concessions and commissions incurred by the selling stockholders in connection with resales of the shares. We have agreed to indemnify the selling stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act and the Exchange Act, or the selling stockholders may be entitled to contribution. The selling stockholders have agreed to indemnify us against certain losses, claims, damages and liabilities, including liabilities under the Securities Act that may arise from written information furnished to us by the selling stockholders specifically for use in this prospectus.

In certain circumstances, we may restrict or suspend offers and sales or other dispositions of the shares under the registration statement of which this prospectus forms a part after the date of this prospectus. In the event of such restriction or suspension, the selling stockholders will not be able to offer or sell or otherwise dispose of the shares of common stock under the registration statement of which this prospectus forms a part.

We or any selling stockholders and any other person participating in the sale of the common stock will be subject to the rules of the Exchange Act. The Exchange Act rules include, without limitation, Regulation M, which may limit the timing of purchases and sales of the common stock by we and selling stockholders and any other such person. In addition, Regulation M may restrict the ability of any person engaged in the distribution of the common stock to engage in market-making activities with respect to the particular common stock being distributed. This may affect the marketability of the common stock and the ability of any person or entity to engage in market-making activities with respect to the common stock.

Once sold under the registration statement of which this prospectus forms a part, the shares of common stock will be freely tradable in the hands of persons other than our affiliates.

The validity of the common stock offered hereby will be passed upon for us by Shearman & Sterling LLP, New York, New York.
