Title: | Life cycle assessment of biochar cofiring with coal | Authors: | Huang Y.-F. Syu F.-S. PEI-TE CHIUEH SHANG-LIEN LO |
Issue Date: | 2013 | Publisher: | Elsevier Ltd | Journal Volume: | 131 | Start page/Pages: | 166-171 | Source: | Bioresource Technology | Abstract: | This study used life cycle assessment software SimaPro 7.2 and impact assessment model IMPACT 2002+ to evaluate the environmental impact and benefits of a biochar cofiring supply chain used for electricity generation. The biochar was assumed to be produced by rice straw torrefaction and the case study was located in Taoyuan County, Taiwan. This supply chain may provide impact reduction benefits in five categories (aquatic ecotoxicity, terrestrial ecotoxicity, land occupation, global warming, and non-renewable energy) but cause higher impacts than coal firing systems in other categories. Damage assessment of cofiring systems indicated that damage to human health was higher while the damage categories of ecosystem quality, climate change, and resources were lower. Carbon reduction could be 4.32 and 4.68metric tons CO2eq/ha/yr at 10% and 20% cofiring ratios, respectively. The improvement of electricity generation efficiency of cofiring systems may be the most important factor for reducing its environmental impact. © 2012 Elsevier Ltd. |
