Debt Disclosure [Abstract]
Notes Payable	Notes PayableThe Company maintains eight separate offtake supply agreements (the “Offtake Agreements”). Two of the eight Offtake Agreements are with the same customer and pertain to supply of product from Origin 1 and Origin 2, respectively. Pursuant to the Offtake Agreements, the Company will construct manufacturing plants with specific capacity and product quality requirements within certain timeframes for the manufacture of product for sale to the counterparties to the agreements, and the counterparties will make minimum annual purchases at a set price, subject to adjustments, all as defined in the agreements. The Company received a $5.0 million prepayment from a customer for product from Origin 1 pursuant to one of these Offtake Agreements, which the Company entered into in November 2016. The prepayment was to be credited against the purchase of products over the term of the Offtake Agreement. The prepayment was secured by a promissory note (the “Promissory Note”) to be repaid in cash in the event that the prepayment could not be credited against the purchase of product, for example, if Origin 1 was never constructed. The Promissory Note was collateralized substantially by Origin 1 and other assets of Origin Material Canada Pioneer Limited. In May 2019, the Company and the customer amended the Offtake Agreement and Promissory Note. The amendment added accrued interest of $0.2 million to the principal balance of the prepayment and provided for the prepayment amount to be repaid in three annual installments rather than being applied against the purchase of product from Origin 1. On August 1, 2022, the Company and the customer further amended and restated the Promissory Note with an aggregate principal amount of $5.2 million, which is the sum of the original principal with accrued interest prior to the amendment. As a result of the amendment, the repayment dates were revised and to allow the customer to offset amounts owed for the purchase of product from the Company’s Origin 1 facility against amounts due under the Promissory Note. The repayment in the amount of $2.7 million is due on September 1, 2024, $1.9 million is due on September 1, 2025, and $1.8 million is due on September 1, 2026 (inclusive of accrued but unpaid interest of 3.5% per annum). At March 31, 2023 and December 31, 2022, the total note principal outstanding was $5.2 million and accrued interest outstanding was $0.7 million and $0.6 million, respectively. In addition, the amendment reflected the customer’s exercise of its option to enter into a new Offtake Agreement to buy a specified annual amount of product from Origin 2 for an initial term of up to 10 years.
