| Life cycle assessment (LCA) is considered as an important method for evaluating industrial chain and products environmental effects, resource consumption and net energy ratio. Nowadays, the method has got more and more attention and begins to be used in the field of biodiesel cleaner production for providing decision basis about sustainable development of industrialization. The LCA system of woody biodiesel, evaluation models and methods, related research status at home and abroad were introduced. The results showed that in the combustion phase, woody biodiesel was more cleanly than petroleum diesel, but was not in the all life phases, mainly related to coal-fired power generation emissions, fertilizer and accessories production emissions. As a low-carbon industry, the greenhouse effect and energy consumption of woody biodiesel were lower than that of petroleum diesel, the maximum emission and consumption stage were planting and production stages. For reducing consumption and emissions, the improvement measures were put forward. The further research on LCA of woody biodiesel in China should be broadened through the construction of industrial standard database, comparative evaluation among different raw materials and production processes, evaluation of economic and ecological service functions. |
