CY2020	us-gaap	Concentration Risk Credit Risk ConcentrationRiskCreditRisk	The Company’s earnings are significantly affected by equity earnings it receives from Tinuum Group. As of December 31, 2020, Tinuum Group has 23 invested RC facilities of which 9 are leased to a single customer. Both Tinuum Group and Tinuum Services expect to significantly wind down their operations by the end of 2021 due to the expected expiration of the Section 45 tax credit period as of December 31, 2021. The loss of Tinuum Group's customers, reduction in revenue streams as a result of lease renewals and the expiration of Section 45 tax credits will have a significant adverse impact on Tinuum Group's financial position, results of operations and cash flows, which in turn will have a material adverse impact on the Company’s financial position, results of operations and cash flows.Concentration of credit riskAs of December 31, 2020, the Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents. The Company holds cash and cash equivalents at three financial institutions as of December 31, 2020. If those institutions were unable to perform their obligations, the Company would be at risk regarding the amount of its cash balance in excess of the federal deposit insurance corporation limits ($250 thousand).
