by Kristi Pihl (Tri-City Herald) A pilot project to produce biofuel using agricultural and organic municipal waste has reached levels that makes the process commercially viable, researchers say.

The project, paid for by the Department of Energy, is within six months of being able to demonstrate the capacity of the BioChemCat process to create biofuel, said Keith Thomsen, assistant director of Washington State University Tri-Cities’ Center for Bioproducts and Bioenergy.

This way of creating biofuel is fuel agnostic, and can be tweaked to use available agricultural waste from a variety of crops including hops, wheat and grapes, Thomsen said.

…The BioChemCat project takes agricultural waste, wood waste or organic materials from municipal solid waste. It uses a “novel” pretreatment method that requires heat and pressure to tear the structure of the waste apart, allowing microorganisms to convert it, Thomsen explained.

The pretreatment is the “heart and soul” of BioChemCat, Thomsen said.

Then, a mixed culture of different microorganisms is used to ferment the pretreated biomass, he said. READ MORE
