Life Cycle Assessment Model for Biomass Fuel Briquetting

Previous Life Cycle Assessment (LCA) studies of biomass briquetting have shown wide variations in the LCA outcomes as a result methodological parameters and technological parameters. An model was therefore developed to enable transparent comparison life cycle environmental impacts with individual or blends feeds variety options. The according standard procedure ISO14044. A comparative approach utilised, set integrated excel worksheets that describe process flows material, energy emissions across different units used developing components. main components include materials inventory databases derived from sources, calculations, user inputs results sections. is open-access accessible format (Microsoft Excel). representative case study mixed rice husks corn cobs validating model. Results showed unit made largest contribution, 42%, total operational system. For all explored this study, range 0.2 0.3 MJ/MJ. same blend ratios, 1.7 MJ/MJ also obtained change other input parameters, sensitivity test. increase husk content increased impact terms global warming potential (kg CO2-eq), acidification SO2-eq), human toxicity 1,4-DB-eq), ozone layer depletion CFC-11-eq), terrestrial ecotoxicity 1,4-DB-eq) per MJ briquette content, it associated lower density, which required for handling.
