废弃电器电子产品产生量估算方法研究趋势分析

TREND ANALYSIS ON ESTIMATION METHOD FOR GENERATION OF WASTE ELECTRICAL AND ELECTRONIC EQUIPMENTS

废弃电器电子产品(WEEE)是世界增长最快的废物流之一,研究其产生量对社会经济和生态可持续发展具有重要意义。现有的WEEE产生量估算方法众多,但对其造成估算结果偏差的原因分析较少。综述了常见的5种估算模型的研究进展,并重点从数据完整性和精度、产品寿命、逆向物流、区域流动角度探讨了估算模型在我国实际应用中存在的局限性。结果表明:通过完善本土数据库、融合多种估算模型、解析资源代谢过程、追踪物质转移过程可提升估算结果的精确性和可靠性,为废弃电器电子产品产生量估算方法的改进和应用提供参考。

Waste electrical and electronic equipments(WEEE)was one of the fastest growing waste streams in the world,so the study on the generation volume of WEEE was of great importance.Although there were many methods for estimating the generation volume,the cause of the bias in the estimation results was rarely analyzed.In this paper,we summarized the research progress of five typical estimation models.Furthermore,we focused on the limitations of their practical application in China from the perspectives of data integrity and accuracy,product life,reverse logistics,and regional mobility.The results showed that the accuracy and reliability of the estimation results could be improved by strengthening local database,integrating multiple estimation models,analyzing the resource metabolism process,and tracking the material transfer process.It was expected to provide references for the improvement and application of estimation method on the generation of WEEE.
