Edeniq Inc., a leading cellulosic and biorefining technology company, and Archer Daniels Midland Co. recently announced that the U.S. EPA has approved Little Sioux Corn Processors’ registration of its 150 million gallon per year Marcus, Iowa, ethanol plant for cellulosic ethanol production. Under the terms of its license agreements with ADM and Little Sioux, Edeniq uses its Pathway Technology to measure the amount of cellulosic ethanol produced, and provides the required information to register for D3 cellulosic renewable identification numbers (RINs) with the EPA.

Little Sioux is the third plant to receive a cellulosic ethanol registration from the EPA after deploying Edeniq’s Pathway Technology. The plant uses ADM’s Clintozyme enzyme to convert lower value corn fiber, which is typically sold as a feed ingredient, into higher value fuel ethanol through an enzymatic process. Registered plants can access D3 RINS, which are worth over $2.50 per gallon in 2017.

“Our customers are at the forefront of cellulosic biofuel production in the United States,” said Brian Thome, president and CEO of Edeniq. “And thanks to the efforts by the EPA in their approval process, our customers are now receiving registration approvals in a shorter time frame, allowing them to generate value from our technology more quickly.”

“We have been able to demonstrate that ADM’s Clintozyme enzyme can provide improved economics and higher yields for ethanol producers, and we are pleased that Little Sioux is now able to take advantage of this technology,” said Del Cahill, general manager, BioAdvantaged Products at ADM.

Steve Roe, general manager of Little Sioux, stated, “We trialed ADM’s Clintozyme cellulase enzyme to increase our ethanol and corn oil yield. We saw positive overall corn to ethanol conversion rates, increased corn oil yields, lower btu’s per gallon, and decreased fouling of piping and evaporator equipment. When we accessed the Edeniq Pathway Technology through the license, Edeniq put the pieces together to allow us to produce D3 RINs, thereby increasing shareholder value.”

“Our team is adding resources to move plants through commercial validation trials and the EPA registration process as quickly as possible, as the current customer backlog has now grown to more than 15 plants,” said Cam Cast, chief operating officer of Edeniq. “These resources will also help us continue to offer the highest level of support to our existing customers, including Little Sioux. We would like to thank the EPA, Little Sioux and ADM teams for their ongoing partnership.”

Edeniq’s Pathway Technology is the lowest-cost solution for producing and measuring cellulosic ethanol from corn kernel fiber utilizing existing fermenters at corn ethanol plants and has produced up to 2.5 percent cellulosic ethanol, up to a 7 percent increase in overall ethanol yield, and additional corn oil recovery. Edeniq is the leader in developing analytical methods to quantify cellulosic ethanol co-produced with conventional ethanol. Edeniq’s EPA approved validation and turnkey registration process provide a solution for generating D3 RINs and other regulatory credits associated with cellulosic ethanol.
