The California Air Resources Board (CARB) has approved Golden Grain Energy for cellulosic ethanol production from corn kernel fibre, according to biotechnology company Edeniq, which has supplied the technology for production.

Golden Grain operates a corn ethanol plant in Mason City, Iowa, which has a capacity of 120 million gallons per year of ethanol. The facility was certified under CARB’s Low Carbon Fuel Standard (LCFS) programme on 5 August, with a carbon intensity (CI) rating of 29.09.

Edeniq’s Intellulose 2.0 technology has enabled the plant to achieve corn kernel fibre ethanol production up to, and sometime exceeding, 4% of total production. Two plants that have already received CARB certification using the same technology achieved average ethanol production of around 3% of the total.

Nine customers using Edeniq’s Intellulose technology have been approved by the US Environmental Protection Agency for D3 RIN generation and/or by CARB for low-CI corn kernel fibre ethanol production. Additionally, six current and existing customers are now using Intellulose 2.0, which builds on a previous version of the technology that measures the cellulosic ethanol produced from a single corn kernel component.

Intellulose 2.0 measure the amount of ethanol produced from multiple different molecules present in corn kernels, quantifying the individual contribution of each component.
