WASTE AND BIOREFINERY - A NEW BOOST FOR DARK FERMENTATION?

摘要

Sustainable management options for organic waste foresee the possibility of using industrial processes to produce energy or commodities from biodegradable materials. Limits on landfill disposal of biodegradable organics and green house gas emission reduction targets posed by the European Union represent an incentive to this approach. Wastes are treated before their final disposal to simultaneusly produce or recover bio-fuels, bulk chemicals, biopolymers or bioproducts for further industrial or commercial applications in a scheme of circular economy (Cossu, 2009). Over the last years biological hydrogen production has arised a growing interest. The production of bio-hydrogen and other biofuels from organic residues could in fact well fit a sustainable energy economy combining use of hydrogen, electricity and batteries to serve as both energy carrier and storage systems (Andrews and Shabani, 2012).
