Collaborative Arrangements And Noncollaborative Arrangement Transaction [Abstract]
DEVELOPMENT PARTNER ARRANGEMENTS	DEVELOPMENT PARTNER ARRANGEMENTS License Agreements On October 16, 2015, Legacy PCT entered into a patent license agreement with P&G (the “Original Patent License Agreement”). Legacy PCT and P&G entered into an Amended and Restated Patent License Agreement on July 28, 2020 (the “Amended and Restated Patent License Agreement”). PCT and P&G entered into a side letter agreement on February 12, 2021 amending certain provisions of the Amended and Restated License Agreement (the “Side Letter Agreement” and, together with the Original Patent License Agreement and the Amended and Restated Patent License Agreement, the “License Agreement”). The License Agreement outlines three phases with specific deliverables for each phase. During Phase 1 of the agreement, P&G provides Legacy PCT with up to one full-time employee to assist in the execution of Legacy PCT’s research and development activities. During Phase 2, P&G provides up to two full-time employees to assist in the execution of Legacy PCT’s research and development activities. In April 2019, Legacy PCT elected to enter into Phase 3 of the agreement and prepaid a royalty payment in the amount of $2.0 million, which will be reduced against future royalties payable as sales occur. Phase 3 of the agreement relates to the commercial manufacture period for the manufacture of the licensed product. This phase includes the construction of the first commercial plant for the manufacture of the licensed product, details on the commercial sales capacity and the pricing of the licensed product to P&G and to third parties. Where the Company has made royalty payments to its product development partners, the Company expenses such payments as incurred unless it has determined that is it probable that such prepaid royalties have future economic benefit to the Company. In such cases prepaid royalties will be reduced as royalties would otherwise be due to the partners. As of December 31, 2022 and December 31, 2021, the Company is in Phase 3 of the agreement and has recorded $2.0 million within prepaid expenses and other non-current assets in the consolidated balance sheets. On November 13, 2019, Legacy PCT entered into a patent sublicense agreement with Impact Recycling Limited (“Impact”) through the term of the patents. The agreement outlines an initial license fee of $2.5 million and royalties on production using the license. In 2020, Legacy PCT paid $0.9 million of the initial license fee, and during the year ended December 31, 2021, the Company paid the remaining $1.6 million of the initial fee. The initial license fee of $2.5 million is recorded in prepaid expenses and other non-current assets in the consolidated balance sheets and will be ratably amortized over the term of the underlying patent using the straight-line method. In May 2021, the Company began using the technology covered by the Impact agreement and commenced amortization as of this date. The remaining balance related to the prepaid initial license fee was $0.2 million and $0.2 million in prepaid expenses and other current assets as of December 31, 2022 and 2021, respectively, and $2.1 million and $2.3 million in prepaid expenses and other non-current assets as of December 31, 2022 and 2021, respectively. Block and Release Agreement On June 23, 2020, Legacy PCT entered into a block and release agreement with Total Petrochemicals & Refining S.A./N.V. (“Total”). Upon execution of the agreement, Total made a prepayment consisting of a payment of $5.0 million for future receipt of resin consisting of recycled polypropylene (“recycled PP”). The prepayment was placed in an escrow account until the “release condition” of the Company closing the bond offering and overall capital funding of at least $370.0 million has occurred. After the Company successfully raised the required capital, the $5.0 million was released during the year ended December 31, 2021 to the Company and recorded as deferred revenue in the consolidated balance sheets. Strategic Alliance Agreement On December 13, 2018, Legacy PCT entered into a strategic alliance agreement with Nestec Ltd. (“Nestle”), which expires on December 31, 2023. Upon execution of the agreement, Nestle committed to provide $1.0 million to Legacy PCT to fund further research and development efforts. The funding provided by Nestle may be convertible, in whole or in part, into a prepaid product purchase arrangement at Nestle’s option, upon the time of product delivery beginning in 2021. Additionally, because the research and development efforts were not successful as of December 31, 2020, up to 50% of the funding may be convertible into a 5-year term loan obligation, payable to Nestle at an interest rate equivalent to the U.S. prime rate. As of the issuance of these statements, Nestle has not elected to convert any funding into a term loan. Legacy PCT received the funding from Nestle on January 8, 2019. The Company has recorded $1.0 million as a deferred research and development obligation within other non-current liabilities as of December 31, 2022 and December 31, 2021. Recognition related to the funding received will be deferred until it is probable that Nestle will not exercise their option. If the prepaid product purchase option is exercised, the obligation will be recognized as an adjustment to the transaction price of future product sales (e.g., net revenue presentation). If the option is not exercised, or in the case of development efforts not being successful, any amounts not converted to a loan obligation will be recognized as a reduction to research and development costs.
