Environmental benefits of waste refrigerator recycling based on IMPACT WORLD+
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.
