Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION.	1. ORGANIZATION Organization and Business The Company is a leading producer and marketer of specialty alcohols and essential ingredients. The Company also produces and markets fuel-grade ethanol. The Company’s production facilities in Pekin, Illinois are located in the heart of the Corn Belt, benefit from low-cost and abundant feedstock and allow for access to many additional domestic markets. In addition, the Company’s ability to load unit trains and barges from these facilities allows for greater access to international markets. The Company’s four production facilities in California, Oregon and Idaho, located in close proximity to both feed and fuel-grade ethanol customers, enjoy unique advantages in efficiency, logistics and product pricing. The Company had a combined production capacity of 450 million gallons per year, as of March 31, 2021, markets, on an annualized basis, over 500 million gallons of alcohols, and produces, on an annualized basis, nearly 1.5 million tons of essential ingredients on a dry matter basis, such as dried yeast, corn gluten meal, corn gluten feed, and distillers grains and liquid feed used in commercial animal feed and pet foods. The Company focuses on four key markets: Health, Home & Beauty Food & Beverage Essential Ingredients Renewable Fuels As of March 31, 2021, the Company was operating at approximately 64% of its then-450 million gallon annual production capacity. As market conditions change, the Company may increase, decrease or idle production at one or more operating facilities or resume operations at any idled facility. Basis of Presentation – Interim Financial Statements Accounts Receivable and Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for balances that appear to have specific collection issues. The collection process is based on the age of the invoice and requires attempted contacts with the customer at specified intervals. If, after a specified number of days, the Company has been unsuccessful in its collection efforts, a bad debt allowance is recorded for the balance in question. Delinquent accounts receivable are charged against the allowance for doubtful accounts once uncollectibility has been determined. The factors considered in reaching this determination are the apparent financial condition of the customer and the Company’s success in contacting and negotiating with the customer. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of ability to make payments, additional allowances may be required. Of the accounts receivable balance, approximately $51,301,000 and $35,839,000 at March 31, 2021 and December 31, 2020, respectively, were used as collateral under Kinergy’s operating line of credit. The allowance for doubtful accounts was $351,000 and $260,000 as of March 31, 2021 and December 31, 2020, respectively. The Company recorded a bad debt expense of $91,000 and $19,000 for the three months ended March 31, 2021 and 2020, respectively. The Company does not have any off-balance sheet credit exposure related to its customers. Financial Instruments Estimates and Assumptions

Retirement Benefits [Abstract]
PENSION PLANS.	8. PENSION PLANS. The Company sponsors a defined benefit pension plan (the “Retirement Plan”) and a health care and life insurance plan (the “Postretirement Plan”). The Company assumed the Retirement Plan and the Postretirement Plan as part of its acquisition of PE Central on July 1, 2015. The Retirement Plan is noncontributory, and covers only “grandfathered” unionized employees at the Company’s Pekin, Illinois facility who fulfill minimum age and service requirements. Benefits are based on a prescribed formula based upon the employee’s years of service. The Retirement Plan, which is part of a collective bargaining agreement, covers only union employees hired prior to November 1, 2010. The Company uses a December 31 measurement date for its Retirement Plan. The Company’s funding policy is to make the minimum annual contribution required by applicable regulations. As of December 31, 2020, the Retirement Plan’s accumulated projected benefit obligation was $24.6 million, with a fair value of plan assets of $17.6 million. The underfunded amount of $7.0 million is recorded on the Company’s consolidated balance sheet in other liabilities. For the three months ended March 31, 2021, the Retirement Plan’s net periodic expense was $22,000, comprised of $151,000 in interest cost and $109,000 in service cost, partially offset by $238,000 of expected return on plan assets. For the three months ended March 31, 2020, the Retirement Plan’s net periodic expense was $48,000, comprised of $173,000 in interest cost and $101,000 in service cost, partially offset by $226,000 of expected return on plan assets. The Postretirement Plan provides postretirement medical benefits and life insurance to certain “grandfathered” unionized employees. Employees hired after December 31, 2000 are not eligible to participate in the Postretirement Plan. The Postretirement Plan is contributory, with contributions required at the same rate as active employees. Benefit eligibility under the plan reduces at age 65 from a defined benefit to a defined dollar cap based upon years of service. As of December 31, 2020, the Postretirement Plan’s accumulated projected benefit obligation was $5.3 million and is recorded on the Company’s consolidated balance sheet in other liabilities. The Company’s funding policy is to make the minimum annual contribution required by applicable regulations. For the three months ended March 31, 2021, the Postretirement Plan’s net periodic expense was $42,000, comprised of $10,000 of interest cost, $26,000 of service cost and $6,000 of amortization expense. For the three months ended March 31, 2020, the Postretirement Plan’s net periodic expense was $59,000, comprised of $38,000 of interest cost, $14,000 of service cost and $7,000 of amortization expense.

The fair value hierarchy prioritizes the inputs used in valuation techniques into three levels, as follows: ● Level 1 – Observable inputs – unadjusted quoted prices in active markets for identical assets and liabilities; ● Level 2 – Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability through corroboration with market data; and ● Level 3 – Unobservable inputs – includes amounts derived from valuation models where one or more significant inputs are unobservable. For fair value measurements using significant unobservable inputs, a description of the inputs and the information used to develop the inputs is required along with a reconciliation of Level 3 values from the prior reporting period. Pooled separate accounts Long-Lived Assets Held-for-Sale Other Derivative Instruments The following table summarizes recurring and nonrecurring fair value measurements by level at March 31, 2021 (in thousands): Fair Value Level 1 Level 2 Level 3 Assets: Derivative financial instruments $ 22,355 $ 22,355 $ — $ — Long-lived assets held-for-sale 57,053 — — 57,053 $ 79,408 $ 22,355 $ — $ 57,053 Liabilities: Derivative financial instruments $ (4,741 ) $ (4,741 ) $ — $ — $ (4,741 ) $ (4,741 ) $ — $ — The following table summarizes recurring and nonrecurring fair value measurements by level at December 31, 2020 (in thousands): Benefit Plan Fair Percentage Value Level 1 Level 2 Level 3 Allocation Assets: Derivative financial instruments $ 17,149 $ 17,149 $ — $ — Long-lived assets held-for-sale 58,295 — — 58,295 Defined benefit plan assets(1) (pooled separate accounts): Large U.S. Equity(2) 5,470 — 5,470 — 31 % Small/Mid U.S. Equity(3) 2,605 — 2,605 — 15 % International Equity(4) 2,921 — 2,921 — 17 % Fixed Income(5) 6,592 — 6,592 — 37 % $ 93,032 $ 17,149 $ 17,588 $ 58,295 Liabilities: $ — $ — $ — $ — (1) Included in other assets in the consolidated balance sheets.

Organization and Business	Organization and Business The Company is a leading producer and marketer of specialty alcohols and essential ingredients. The Company also produces and markets fuel-grade ethanol. The Company’s production facilities in Pekin, Illinois are located in the heart of the Corn Belt, benefit from low-cost and abundant feedstock and allow for access to many additional domestic markets. In addition, the Company’s ability to load unit trains and barges from these facilities allows for greater access to international markets. The Company’s four production facilities in California, Oregon and Idaho, located in close proximity to both feed and fuel-grade ethanol customers, enjoy unique advantages in efficiency, logistics and product pricing. The Company had a combined production capacity of 450 million gallons per year, as of March 31, 2021, markets, on an annualized basis, over 500 million gallons of alcohols, and produces, on an annualized basis, nearly 1.5 million tons of essential ingredients on a dry matter basis, such as dried yeast, corn gluten meal, corn gluten feed, and distillers grains and liquid feed used in commercial animal feed and pet foods. The Company focuses on four key markets: Health, Home & Beauty Food & Beverage Essential Ingredients Renewable Fuels As of March 31, 2021, the Company was operating at approximately 64% of its then-450 million gallon annual production capacity. As market conditions change, the Company may increase, decrease or idle production at one or more operating facilities or resume operations at any idled facility.
Basis of Presentation	Basis of Presentation – Interim Financial Statements
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for balances that appear to have specific collection issues. The collection process is based on the age of the invoice and requires attempted contacts with the customer at specified intervals. If, after a specified number of days, the Company has been unsuccessful in its collection efforts, a bad debt allowance is recorded for the balance in question. Delinquent accounts receivable are charged against the allowance for doubtful accounts once uncollectibility has been determined. The factors considered in reaching this determination are the apparent financial condition of the customer and the Company’s success in contacting and negotiating with the customer. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of ability to make payments, additional allowances may be required. Of the accounts receivable balance, approximately $51,301,000 and $35,839,000 at March 31, 2021 and December 31, 2020, respectively, were used as collateral under Kinergy’s operating line of credit. The allowance for doubtful accounts was $351,000 and $260,000 as of March 31, 2021 and December 31, 2020, respectively. The Company recorded a bad debt expense of $91,000 and $19,000 for the three months ended March 31, 2021 and 2020, respectively. The Company does not have any off-balance sheet credit exposure related to its customers.
