Pay vs Performance Disclosure [Table] |  |  |  |
Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE We are required to calculate and present the following compensation information in the tabular format prescribed by the SEC. The Compensation Discussion and Analysis and other executive compensation tables above should be read in conjunction with this section to gain a complete understanding of our executive compensation philosophy, programs and decisions. The tables and discussion below refer to an SEC-prescribed calculation of compensation actually paid, referred to as “CAP”. However, CAP does not correlate to the total amount of compensation that the executive realized during the year. CAP is a detailed calculation that includes adjustments to Total Compensation as reported in the Summary Compensation Table (the “SCT”) to reflect the increase (or decrease) in value of equity compensation over the course of the year, including equity compensation granted in prior years and equity compensation remaining unvested as of year-end. The equity compensation values used to determine CAP are calculated in accordance with ASC Topic 718, based on various methodologies and assumptions. The amount of compensation that the executive will actually realize when such equity awards vest or options are exercised maybe materially different from the amounts used in the CAP calculation. The table below includes our Operating EBITDA annual cash incentive performance measure as the Company Selected Measure (“CSM”) that management believes is the most important annual financial performance measure used to link executive pay and Company performance in 2022. This measure is also discussed in our Compensation Discussion and Analysis and is generally defined as the Company’s income from operations, excluding depreciation, depletion and amortization, “Restructuring” and “(Gain) Loss from Divestitures, Asset Impairments and Unusual Items, Net” reported in our Annual Report on Form 10-K, with adjustments discussed in footnote (4) below. Operating EBITDA presented in this proxy statement is a non-GAAP measure and is defined differently than Operating EBITDA reported in the Company’s quarterly earnings press release.

​ (a) Stock awards for all NEOs include annual grants of TSR PSUs and Cash Flow PSUs. The fair value of an unvested TSR PSU is calculated using a multifactor Monte Carlo model, and because total shareholder return is a market condition, projected achievement is embedded in the fair value. The fair value of an unvested Cash Flow PSU is equal to the average of the high and low market price of our Common Stock on the given date; we then multiply the fair value of a Cash Flow PSU by our projection, for accounting purposes, of the probable outcome of the Cash Flow Generation performance measure applicable to such PSUs, based on results to-date and forecast. The following grid summarizes the projected probable outcomes utilized to calculate the value of unvested Cash Flow PSUs at year-end for years prior to the end of the performance period for purposes of CAP: ​
​ | Projected Payout of Unvested Cash Flow PSUs at Year-End | ​ | ​ | 2022 | ​ | ​ | 2021 | ​ | ​ | 2020 | ​ | ​ | 2019 | ​

Stock awards also includes RSUs for Ms. Hemmer that vested in 2020; RSUs for Mr. Batchelor that vested in 2020 and 2021; RSUs that were granted to Mr. Boettcher in 2021; and RSUs that were granted to Ms. Rankin, Mr. Morris, Ms. Hemmer and Mr. Batchelor in 2022. The fair value of an RSU is equal to the average of the high and low market price of our Common Stock on the given date. (b) Option awards include fair values, calculated using a Black-Scholes option pricing model, for stock options granted annually to our NEOs. ​ (2) The Non-CEO NEOs for purposes of the 2022 and 2020 disclosures include Ms. Rankin, Mr. Morris, Mr. Batchelor and Ms. Hemmer. The Non-CEO NEOs for purposes of the 2021 disclosures include Ms. Rankin, Mr. Morris, Mr. Boettcher and Ms. Hemmer. ​ (3) Total shareholder return (“TSR”) is based on a hypothetical $100 investment on December 31, 2019. The TSR amounts shown for 2020 represent the value of that $100 investment on December 31, 2020, and TSR is then calculated, on a cumulative basis, as of December 31, 2021 and December 31, 2022. The Peer Group TSR refers to the Dow Jones Waste & Disposal Services Index. ​ (4) When establishing the 2022 compensation performance levels, the MD&C Committee defined Operating EBITDA to exclude the impacts of the Company’s recycling brokerage business, which increased net Operating EBITDA results by $7 million. The MD&C Committee did not make any adjustments to the defined calculation of Operating EBITDA for 2021 and 2022. The MD&C Committee approved adjustments to the calculation of Operating EBITDA for 2020 on a basis consistent with the reporting of our 2020 financial results, excluding (a) $155 million of costs related to the acquisition and integration of ADS; (b) $46 million in costs in connection with COVID-19 and (c) $27 million in costs related to strategic initiatives launched in 2020 after the performance measures had been established. |  |  |

Non-GAAP Measure Description [Text Block] | (4) When establishing the 2022 compensation performance levels, the MD&C Committee defined Operating EBITDA to exclude the impacts of the Company’s recycling brokerage business, which increased net Operating EBITDA results by $7 million. The MD&C Committee did not make any adjustments to the defined calculation of Operating EBITDA for 2021 and 2022. The MD&C Committee approved adjustments to the calculation of Operating EBITDA for 2020 on a basis consistent with the reporting of our 2020 financial results, excluding (a) $155 million of costs related to the acquisition and integration of ADS; (b) $46 million in costs in connection with COVID-19 and (c) $27 million in costs related to strategic initiatives launched in 2020 after the performance measures had been established |  |  |
