Alliance BioEnergy + has been developing bolt-on cellulosic ethanol technology and the company has announced that its results from the testing of its pilot plant are positive. The tests looked at distillers grains (DDGs) and corn kernel fiber and it ability to be converted to cellulosic ethanol using the CoPro Max separation unit designed in conjunction with Harvest Technology. The two byproducts can be converted into cellulosic ethanol, adding millions of gallons of additional ethanol production to an existing facility.
The pilot testing has demonstrated that the corn kernel fiber is an ideal feedstocks when used in the CTS process and converts nearly 100 percent of the available sugars in as little as 12 minutes, according to Alliance BioEnergy. When combined with the CoPro Max system (to an 100 million gallons per year) corn ethanol plant), the company is reporting the CTS process adds nearly 12 million gallons of cellulosic ethanol to the plant and recovers most all of the highly valuable corn oil and proteins, from the DDGs. In addition, Alliance BioEnergy is reporting the sale of the additional ethanol, corn oil and proteins as well as cellulosic credits could add an additional $48 million to the bottom-line of a typical 100 mmgy corn ethanol plant.
Advantages of the bolt-on technology, says Alliance, include no need to purchase or transport feedstock to the plant nor is there a pre-treatment process.
Alliance BioEnergy is reporting its intentions to build and install the first unit in an existing ethanol plant this year and begin marketing the combined unit to U.S. ethanol plants later this year.
