Towards Developing Anaerobic Digestion Based Biorefinery – Research On Food Wastes As Feedstock

Oct 19, 2011

Shulin Chen

Anaerobic digestion (AD) is a proven technology for waste treatment. However, as the organic material becomes more valuable and being treated as resources, traditional AD process is no longer adequate. The Bioprocessing and Bioproduct Engineering Laboratory at Washington State University has been...

BIOCORE - On a Paradigm for the Design and Synthesis of Real-Life Biorefineries

Oct 19, 2011

Aikaterini D. Mountraki

As oil is a fast depleting resource (BP, 2010), much is expected by the production of biofuels as valid options to replace fossil-oil transportation fuels. Biorefineries are not an entirely new concept. Many of the traditional biomass conversion technologies such as the sugar and paper industries...
