废冰箱回收利用环境效益评估——基于IMPACT WORLD+方法

Environmental benefits of waste refrigerator recycling based on IMPACT WORLD+

废电器是产生量大且增速快的一类固体废物.我国构建的废电器回收体系是实施碳达峰?碳中和的重要举措,但废电器回收利用体系的环境效益尚不清楚.利用IMPACTWORLD+方法,从不同环境影响类型出发评估废电器回收处理的环境效益,并通过损害类型指标量化评价.结果表明,废冰箱回收利用的损害类型指标“人体健康”和“生态环境质量”的结果分别为-10592.501EUR2015和-8211.357EUR2015,合计为-18803.857EUR2015,即环境收益相当于18803.857EUR2015.据此估算,中国2021年废电器回收处理体系中仅废冰箱回收利用的环境收益可达12.82亿EUR2015.研究结果表明废电器回收处理的环境收益十分可观,有望为废电器回收行业的可持续发展提供新的助力.

Waste electrical and electronic equipment(WEEE) is a kind of solid waste with large quantity and rapid growth. The WEEE recycling system established by China has become an important measure to achieve carbon neutrality. However, the environmental benefits of the recycling system are yet unclear. In this study, the IMPACT WORLD+ method was used to assess the environmental benefits of the system quantitatively based on the damage indicators of various environmental impacts. The results showed that the total damage indicators of refrigerator recycling were-18803.857EUR2015 where the damage indicators of human health and ecosystem quality were-10592.501EUR2015 and-8211.357EUR2015, respectively. In that case, the environmental benefits were equivalent to 18803.857EUR2015. Therefore, it was estimated that the environmental benefits of refrigerators recycling of the Chinese WEEE recycling system could reach 1.282 billion EUR2015 in 2021. The research indicated that the environmental benefits of WEEE recycling were significant to provide new assistance for the sustainable development of the WEEE recycling industry.
