Abstract

Abstract

In recent years, harmless and resource utilization of food waste are advocated researching and developing directions, which also play important role in public health and sustainable development. This paper selected two food waste treatment plants in Tangshan and Xiamen for investigation, representing two typical food waste treatment modes in China. The characterization, standardization, and normalization were conducted by method IMPACT2002+ in Simapro software. In addition, their economic benefits were briefly evaluated. The results demonstrated that case 1(Tangshan) dominated the environmental impact results of 13 midpoint indicators, such as aquatic ecotoxicity, non-renewable resources, and terrestrial ecotoxicity. The total potential environmental impacts of co-production of case 1(Tangshan) and case 2(Xiamen) were -26mpt and 22.7mpt, respectively. Thus, the environmental benefits of case 1 predominated. Comparing to case1, case2 has a shorter payback period and better economic benefits.
