Accounting Policies [Abstract]
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted CashThe Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
Inventory	Inventory Inventories of products consist of feedstocks, refined petroleum products and recovered ferrous and non-ferrous metals and are reported at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (“FIFO”) method. The Company reviews its inventory commodities for impairment whenever events or circumstances indicate that the value may not be recoverable.
Impairment of long-lived assets	Impairment of long-lived assetsThe Company evaluates the carrying value and recoverability of its long-lived assets when circumstances warrant such evaluation by applying the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) regarding long-lived assets. It requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable through the estimated undiscounted cash flows expected to result from the use and eventual disposition of the assets. Whenever any such impairment exists, an impairment loss will be recognized for the amount by which the carrying value exceeds the fair value. The Company determined that no long-lived asset impairment existed during the three and nine months ended September 30, 2021.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results could differ from these estimates. Any effects on the business, financial position or results of operations from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known.
Reclassification of Prior Year Presentation	Reclassification of Prior Year PresentationCertain prior period amounts have been reclassified to conform to current period presentation. These reclassifications had no effect on the reported results of operations.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interests As more fully described in “Note 14. Share Purchase and Subscription Agreements”, the Company is party to put/call option agreements with the holder of Vertex Refining Myrtle Grove LLC (“MG SPV”) and HPRM LLC, a Delaware limited liability company, (“Heartland SPV”), which entities were formed as special purpose vehicles in connection with the transactions described in greater detail below, non-controlling interests. The put options permit MG SPV’s and Heartland SPV’s non-controlling interest holders, at any time on or after the earlier of (a) the fifth anniversary of the applicable closing date of such issuances and (ii) the occurrence of certain triggering events (an “MG Redemption” and “Heartland Redemption”, as applicable) to require MG SPV and Heartland SPV to redeem the non-controlling interest from the holder of such interest. Per the agreements, the cash purchase price for such redeemed Class B Units (MG SPV) and Class A Units (Heartland SPV) is the greater of (y) the fair market value of such units (without discount for illiquidity, minority status or otherwise) as determined by a qualified third party agreed to in writing by a majority of the holders seeking an MG SPV Redemption and Heartland SPV Redemption and Vertex Operating, LLC, our wholly-owned subsidiary (“Vertex Operating”) (provided that Vertex Operating still owns Class A Units (as to MG SPV) or Class B Units (as to Heartland SPV) on such date, as applicable) and (z) the original per-unit price for such Class B Units/Class A Units plus any unpaid Class A/Class B preference. The preference is defined as the greater of (A) the aggregate unpaid “Class B/Class A Yield” (equal to an annual return of 22.5% per annum) and (B) an amount equal to fifty percent (50%) of the aggregate capital invested by the Class B/Class A Unit holders. The agreements also permit the Company to acquire the non-controlling interest from the holders thereof upon certain events. Applicable accounting guidance requires an equity instrument that is redeemable for cash or other assets to be classified outside of permanent equity if it is redeemable (a) at a fixed or determinable price on a fixed or determinable date, (b) at the option of the holder, or (c) upon the occurrence of an event that is not solely within the control of the issuer. Based on this guidance, the Company has classified the MG SPV and Heartland SPV non-controlling interests between the liabilities and equity sections of the accompanying September 30, 2021 and December 31, 2020 consolidated balance sheets. If an equity instrument subject to the guidance is currently redeemable, the instrument is adjusted to its maximum redemption amount at the balance sheet date. If the equity instrument subject to the guidance is not currently redeemable but it is probable that the equity instrument will become redeemable (for example, when the redemption depends solely on the passage of time), the guidance permits either of the following measurement methods: (a) accrete changes in the redemption value over the period from the date of issuance (or from the date that it becomes probable that the instrument will become redeemable, if later) to the earliest redemption date of the instrument using an appropriate methodology, or (b) recognize changes in the redemption value immediately as they occur and adjust the carrying amount of the instrument to equal the redemption value at the end of each reporting period. The amount presented in temporary equity should be no less than the initial amount reported in temporary equity for the instrument. Because the MG SPV and Heartland SPV equity instruments will become redeemable solely based on the passage of time, the Company determined that it is probable that the MG SPV and Heartland SPV equity instruments will become redeemable. The Company has elected to apply the second of the two measurement options described above. An adjustment to the carrying amount of a non-controlling interest from the application of the above guidance does not impact net income or loss in the consolidated financial statements. Rather, such adjustments are treated as equity transactions.
Variable Interest Entities	Variable Interest Entities The Company accounts for the investments it makes in certain legal entities in which equity investors do not have (1) sufficient equity at risk for the legal entity to finance its activities without additional subordinated financial support, (2) as a group (the holders of the equity investment at risk), either the power, through voting or similar rights, to direct the activities of the legal entity that most significantly impacts the entity’s economic performance, or (3) the obligation to absorb the expected losses of the legal entity or the right to receive expected residual returns of the legal entity. These certain legal entities are referred to as “variable interest entities” or “VIEs.” The Company consolidates the results of any such entity in which it determines that it has a controlling financial interest. The Company has a “controlling financial interest” in such an entity if the Company has both the power to direct the activities that most significantly affect the VIE’s economic performance and the obligation to absorb the losses of, or right to receive benefits from, the VIE that could be potentially significant to the VIE. On a quarterly basis, the Company reassesses whether it has a controlling financial interest in any investments it has in these certain legal entities.
Assets and Liabilities Held for Sale/Discontinued Operations	Assets and Liabilities Held for Sale The Company classifies disposal groups as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the disposal group; (2) the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; (3) an active program to locate a buyer or buyers and other actions required to complete the plan to sell the disposal group have been initiated; (4) the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify for recognition as a completed sale, within one year, except if events or circumstances beyond the Company’s control extend the period of time required to sell the disposal group beyond one year; (5) the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A disposal group that is classified as held for sale is initially measured at the lower of its carrying amount or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. No loss was recognized during the periods presented. Subsequent changes in the fair value of a disposal group less any costs to sell are reported as an adjustment to the carrying amount of the disposal group, as long as the new carrying amount does not exceed the carrying amount of the asset at the time it was initially classified as held for sale. Upon determining that a disposal group meets the criteria to be classified as held for sale, the Company reports the assets and liabilities of the disposal group for all periods presented in the line items assets held for sale and liabilities held for sale, respectively, in the consolidated balance sheets. Discontinued Operations The results of operations of a component of the Company that can be clearly distinguished, operationally and for financial reporting purposes, that either has been disposed of or is classified as held for sale is reported in discontinued operations, if the disposal represents a strategic shift that has, or will have, a major effect on the Company’s operations and financial results.
