| 摘 要： | 以唐山和厦门2处餐厨垃圾处理厂为例，利用Simapro软件中IMPACT2002+方法对2种不同餐厨垃圾处理模式作特征化、标准化以及归一化分析。同时，针对不同处理模式的经济效益开展评价。结果表明:案例1（唐山）在水生生态毒性、非可再生资源、陆地生态毒性等13个中点指标环境影响结果占优；案例1（唐山）与案例2（厦门）的总环境影响潜值分别为-26，22.7mpt。因此，案例1的环境效益占优；案例1比案例2的投资回收期更短，经济效益更佳。

| 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. |
