Energy Efficiency and Life Cycle Assessment with System Dynamics of Electricity Production from Rice Straw Using a Combined Gasification and Internal Combustion Engine

This study assessed the environmental performance and energy efficiency of electricity generation from rice straw using a combined gasification internal combustion engine (G/ICE). A life cycle assessment (LCA) was performed to consider conversion straw, production which based on Philippine farming practice. Rice is treated as milled coproduct assumes an burden allocated by mass. The results impact for climate change used directly in system dynamic model plot accumulated greenhouse gas emissions compare with various cases order perform sensitivity analyses. At productivity 334 kWh/t, global warming potential (GWP) equal 0.642 kg CO2-eq/MJ, 27% lower than GWP on-site burning. Mitigating biogenic methane flooded fields could reduce 34%, while zero net carbon can be achieved at 2.78 CO2/kg sequestration. Other sources (GHG) are use fossil fuels chemicals agricultural use. machinery transport lorries has highest eutrophication human toxicity, application pesticides fertilizers ecotoxicity. biomass ratio (BER) (NER) 0.065 1.64, respectively.
