Life Cycle Sustainability Assessment (LCSA) of Phosphorus Recycling Policy of Japan

本研究旨在评估一国磷肥消费的可持续性。我们已经制定了一个社会生命周期评估(SLCA)框架，以系统地半量化“隐藏”的社会影响。这些问题包括无资源国家的磷安全、采矿国的人权冲突等。我们的结果表明，尽管生产回收磷肥的成本高于进口矿物磷肥，但供应链中的社会影响大多可以得到缓解。这位研究人员在2017年7月发表在《可持续发展》杂志上，题为《用社会生命周期评估支持磷回收政策：日本的案例》，对日本使用该框架的案例进行了研究。

This study aims to assess the sustainability of P fertilizers consumption in a country. We has developed a Social Life Cycle Assessment (SLCA) framework to semi-quantify the "hidden" social impacts in a systematic manner. These include issues like P security of countries without the resource, human right conflicts in mining countries, etc. Our results showed that, although producing recycled-P fertilizers cost more than importing mineral-P fertilizers, social impacts in the supply chains could mostly be alleviated. A case study of Japan using the developed framework has been published in journal, Sustainability, in July 2017, “Support Phosphorus Recycling Policy with Social Life Cycle Assessment: A Case of Japan” by the researcher.
