Earthanol is an early-stage company that is developing a project to convert waste-products to ethanol. Unlike typical ethanol producers, Earthanol is trying to utilize a cheese industry waste called whey permeate, an acidic by-product that is generally considered environmentally harmful. Earthanol will also try to utilize forestry biomass and municipal waste containing high energy content.
Ethanol-analyst Rick Kment of DTM said that Earthanol’s way to produce ethanol will probably not be a significant competitor to corn-ethanol in the short term, but he said it was good to focus on alternatives to corn-based ethanol."
