By contrast to other processes, our membrane technology needs no auxiliary chemicals; nor does it generate any solid wastes or effluents that would need to be disposed of. The technology is based on membranes produced from high-performance polymers that in the past have been processed into fibers and used in hot-gas filtration.
Immediate applications include processing municipal sewage sludge, processing waste streams from the ethanol industry and converting algae to fuel. We use hot water to depolymerize the cellulose, lignins, lipids and other polymers contained in the biomass. Our process is similar to that used by several companies worldwide.
