Lifecycle assessment of the economic, environmental and energy performance of Jatropha curcas L. biodiesel in China

摘要: Due to issues relating the sustainability of biofuel production, second generation has attracted much attention. As a promising feedstock biodiesel, Jatropha curcas L. (JCL) is being massively planted on marginal land in China, but its viability as source not been systematically assessed. This paper performed lifecycle assessment economic, environmental and energy (3E) performance JCL assuming oil either used for direct blending with diesel or further processed into methyl ester (JME). The results show that, at current technical levels, production biodiesel financially infeasible, positive performance. Despite additional cost incurred transesterification process, net present value JME slightly higher than that when part allocated co-product, i.e., glycerin. compared diesel, consumption per liter can reduce 7.34 kg 8.04 CO(2) equivalent, respectively. balances both are 1.57 1.47, respectively, terms ratio heat input. main factors affecting 3E seed yield, co-product output, farm (C) 2011 Elsevier Ltd.
