The companies announced today that they have formed a joint development project for more efficient and low-cost ethanol production using ACT's Sewage Recycling System to produce the waste-based feedstock Recyllose.
Qteros and ACT found that an ethanol production plant can produce 120-135 gallons of ethanol per ton of Recyllose™.
"A typical cellulosic ethanol plant would have to produce roughly 20-30 million gallons per year (MGY) in order to be profitable," says Qteros CEO William Frey. "With the proposed Qteros-ACT process, production with these economics could be viable at a smaller scale."Qteros said Recyllose improves cellulosic plant operational efficiency by 20% over higher lignin content feedstocks. A wastewater plant that handles 150 million gal/day (serving a population of about 2 million people) is said to be sufficient to supply a smaller-scale ethanol plant with cellulose.
The companies said they are the first to demonstrate commercial success in creating ethanol from the cellulose in municipal and agricultural liquid waste, and to offer a process that all municipalities can use to help reduce expenses.
