Assessing Negative Emissions in the Production of Ethylene from Biomass

P. Haro, P. Ollero, F. Trippe & F. Vidal-Barrero
The assessment of sustainability of the production of ethylene from biomass (bio-ethylene) differs from that of biofuels, because of the different final use of the bio-ethylene (in general of all bio-chemicals). Several alternative routes for the production of bio-ethylene are identified, although only two platform chemicals: ethanol and DME (dimethyl ether). Using a modified version of the European methodology for the sustainability assessment of biofuels, the GHG emissions for the production of bio-ethylene have been...
