摘要
生物可降解塑料近年来在众多领域得到了广泛应用,废弃后的生物可降解塑料(WBP)制品容易对环境造成污染,其回收处理与资源化利用是这类塑料规模化应用的重要保障.本文介绍了WBP的主要处理方法,重点对机械回收、化学回收、生物处理、填埋、焚烧和升级利用进行了阐述,进一步分析了在回收处理过程中遇到的问题,预测了未来发展的趋势,以期为WBP的绿色处理与资源高效再生循环提供指导.
Biodegradable plastics have been widely applied in many fields in recent years.Waste biodegradable plastics(WBP)products may easily cause environmental pollution,thus the disposal and resource utilization of WBP are important guarantees for large-scale application of this type of plastics.This paper summarized the main disposal approaches of WBP,especially focused on mechanical recycling,chemical recycling,biological treatment,landfill,incineration and upgrade utilization.Furthermore,the problems encountered in the treatment process of WBP were systematically analyzed,and the future development trend of WBP recycling was predicted.The main purpose is,to provide guidance for the green and efficient treatment of WBP.
