Abstract
A life cycle assessment study of the biomass‐to‐oil (BTO®) process based on the fast ablative pyrolysis of wood chips from forest residues has been performed. The planned system consists of eight pyrolyzers with a throughput of 6 tpd each. The bio‐oil will be burnt in eight modified diesel engines with a capacity of 315 kWhel each. The results were compared with a reference system (fossil diesel‐fueled CHP). The comparison is made for the production of 1 kWh of electrical energy (kWhel) and shows significant differences for global warming potential (GWP~100~: −87.7%), eutrophication potential (EP: +23.2%), acidification potential (AP: −44.6%), photochemical ozone creation potential (POCP: −63.6%), and ozone depletion potential (ODP: −92.4%). The results of the BTO‐CHP‐system show lower environmental impact values in all environmental impact categories except for the EP‐value, which exceeds the reference due to the application of bio‐oil additives derived from agricultural production. © 2010 American Institute of Chemical Engineers Environ Prog, 2010
