dc.description.abstract | The use of biomass for production of chemicals is gaining interest because of its potential to
contribute towards a reduction in greenhouse gas emissions and other environmental benefits
linked to the substitution of fossil resources. But, conversely to biofuels, studies focusing on
environmental impacts of biomass-derived chemicals are scarce. This paper uses life cycle
assessment to evaluate the environmental sustainability of bio-ethylene from poplar produced by
the following three thermo-chemical routes: direct and indirect dehydration of ethanol and
production of olefins via dimethyl ether. The indirect route is the best option for most impact
categories for all three allocation methods considered: system expansion, economic and energy
basis. However, the dimethyl ether-to-olefins route has the lowest global warming potential. In
comparison to ethylene produced bio-chemically from sugar beet, the thermo-chemical indirect
route has lower impacts for all categories except human, terrestrial and freshwater toxicities. All
three thermo-chemical alternatives show a significant reduction in global warming potential (up to
105% in the case of dimethyl ether-to-olefins) and depletion of fossil fuels when compared to
conventional ethylene production from fossil fuels. However, the results also suggest that bioethylene produced by any of the three thermo-chemical routes would lead to a significant increase
in most other impact categories relative to fossil fuels. Therefore, while trying to reduce
greenhouse gas emissions, the overall environmental sustainability of bio-ethylene suffers from the
increase in other environmental impacts. | es |
