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.
Accounts Receivable	Accounts Receivable Accounts receivable represents amounts due from customers. Accounts receivable are recorded at invoiced amounts, net of reserves and allowances, do not bear interest and are not collateralized. The Company uses its best estimate to determine the required allowance for doubtful accounts based on a variety of factors, including the length of time receivables are past due, economic trends and conditions affecting its customer base, significant one-time events, and historical write-off experience. Specific provisions are recorded for individual receivables when we become aware of a customer’s inability to meet its financial obligations. The Company reviews the adequacy of its reserves and allowances quarterly. Receivable balances greater than 90 days past due are individually reviewed for collectability and if deemed uncollectible, are charged off against the allowance accounts after all means of collection have been exhausted and the potential for recovery is considered remote.
Inventory and Obligations Under Inventory Financing Agreements	Inventory and Obligations Under Inventory Financing Agreements Mobile Refinery. Inventories at the recently acquired Mobile Refinery consist of crude oil and refined petroleum products. Simultaneously with the acquisition of the Mobile Refinery, the Company entered into an inventory financing agreement with Macquarie Energy North America Trading Inc. (“Macquarie”) under which Macquarie agreed to finance all the crude oil utilized at the Mobile Refinery under procurement contracts. In addition, the Company became a party to a Supply and Offtake Agreement with Macquarie. Under this arrangement, the Company purchases crude oil supplied from third-party suppliers and Macquarie provides credit support for certain of these purchases. Macquarie holds title to all crude oil and refined products inventories at all times, except for liquefied petroleum gases and sulfur, which the Company has pledged, together with all receivables arising from the sales of such inventories. The crude oil remains in the legal title of Macquarie and is stored in our storage tanks governed by a storage agreement. Legal title to the crude oil passes to us at the tank outlet. After processing, Macquarie takes title to the refined products stored in our storage tanks until they are sold to our retail locations or to third parties. We record the inventory owned by Macquarie on our behalf as inventory with a corresponding accrued liability on our balance sheet because we maintain the risk of loss until the refined products are sold to third parties and we have an obligation to repurchase it. The valuation of our repurchase obligation requires that we make estimates of the prices and differentials assuming settlement occurs at the end of the reporting period. Hydrocarbon inventories at the Mobile Refinery are stated at the lower of cost or net realizable value using the weighted average inventory accounting method. Estimating the net realizable value of our inventory requires management to make assumptions about the timing of sales and the expected proceeds that will be realized for these sales. See Note 9 “Inventory” and Note 10 “Inventory Financing Agreement” for more information. Other locations. Inventories from our legacy business consist of feedstocks and refined petroleum products and recovered ferrous and non-ferrous metals. These commodity inventories are stated at the lower of cost or net realizable value using the first-in, first-out (“FIFO”) accounting method.
Revenue Recognition	Revenue RecognitionOur revenues are generated through the sale of refined petroleum products and terminalling and storage services. We recognize revenue from product sales at prevailing market rates at the point in time in which the customer obtains control of the product. Terminalling and storage revenues are recognized as services are rendered, and our performance obligations have been satisfied once the product has been transferred back to the customer. These services are short-term in nature, and the service fees charged to our customers are at prevailing market rates. The timing of our revenue recognition may differ from the timing of payment from our customers. A receivable is recorded when revenue is recognized prior to payment and we have an unconditional right to payment.
Environmental Reserves	Environmental Reserves We accrue for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. The liability represents the expected costs of remediating contaminated soil and groundwater at the site. Costs of future expenditures for environmental remediation obligations are discounted to their present value.
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. Long-lived assets are 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.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interests As more fully described in “Note 22. Non-Controlling Interests”, the Company was 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 in non-controlling interests. The put options permited 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. 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 classified the MG SPV and Heartland SPV non-controlling interests between the liabilities and equity sections of the accompanying 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 were to 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 would become redeemable. The Company 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 loss in the consolidated financial statements. Rather, such adjustments are treated as equity transactions and adjustment to net loss in determining net loss available to common stockholders for the purpose of calculating earnings per share. On April 1, 2022, the Company redeemed the non-controlling interest holder's interest of MG SPV, and on May 26, 2022, the Company redeemed the non-controlling interest holder's interest of Heartland SPV.
Variable Interest Entities	Variable Interest Entities The Company determines whether each business entity in which it has equity interests, debt, or other investments constitutes a variable interest entity (“VIE”) based on consideration of the following criteria: (i) the entity lacks sufficient equity at-risk to finance its activities without additional subordinated financial support, or (ii) equity holders, as a group, lack the characteristics of a controlling financial instrument. If an entity is determined to be a VIE, the Company then determines whether to consolidate the entity as the primary beneficiary. The primary beneficiary has both (i) the power to direct the activities that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the entity.
Assets and Liabilities Held for Sale	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	Discontinued OperationsThe 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.
New Accounting Pronouncements	New Accounting Pronouncements Accounting pronouncements adopted by the Company in 2022. In August 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity to simplify the accounting for convertible debt and other equity-linked instruments. The new guidance simplifies the accounting for convertible instruments by eliminating the cash conversion and beneficial conversion feature models used to separately account for embedded conversion features as a component of equity. Instead, the entity will account for the convertible debt or convertible preferred stock securities as a single unit of account, unless the conversion feature requires bifurcation and recognition as derivatives. Additionally, the guidance requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and include the effect of potential share settlement for instruments that may be settled in cash or shares. The Company adopted this new guidance as of January 1, 2022, under the modified retrospective method. On January 20, 2022, our shareholders approved the issuance of shares of our common stock issuable upon the conversion of our $155 million aggregate principal amount at maturity 6.25% Convertible Senior Notes due 2027 (the "Convertible Senior Notes"), the $79 million derivative liabilities were recorded as additional paid-in capital. Accounting pronouncements not yet adopted. The Company has not identified any recent accounting pronouncements that are expected to have a material impact on our financial condition, results of operations or cash flows upon adoption.
