Life cycle assessment of bioethanol production from feedstocks in Thailand
Abstract:
An analysis of mass balance, energy performance, and environmental impact assessment were performed to evaluate bioethanol production in Thailand. Thailand is an agricultural country, Thai government plans to increase the use of alternative energy to 20 percent by 2022. One of the primary campaigns is to promote a bioethanol production from abundant biomass resources such as bitter cassava, molasses and sugarcane. The bioethanol production is composed of three stages: cultivation, pretreatment, and bioethanol conversion. All of mass, material, fuel, and energy were calculated to determine the environmental impact of three bioethanol production: bioethanol productions from cassava, bioethanol production from molasses, and bioethanol production from rice straw. Environment impacts in this thesis are climate change, human toxicity, fresh water toxicity, terrestrial toxicity, eutrophication, and acidification. In addition, to better evaluate the impact assessment of each bioethanol production options, we scored the impact severity using LCA normalization. The results showed that bioethanol production from cassava has the best environmental performance. Cassava-based bioethanol production contributes less impact when compared to the other processes
