Abstract

Each nation has chosen a double-carbon (carbon neutrality/emission peak) policy in line with the objectives of the Paris Agreement to meet human development demands. An estimated 8 million tons of plastic waste related to the epidemic have been generated globally, highlighting an urgent need to halt or at least reduce plastic pollution. The research on degradable polymers that can decompose during composting or under illumination is becoming increasingly crucial. This paper provides a summary of various ester-bonded degradable plastic polymers, including concepts and mechanisms related to water degradation, photo degradation, and bio degradation. It also reviews important degradable agents and examines several ester-bonded plastic polymers currently used in commerce. The limitations and potential applications of these ester-bonded degradable polymers are compared and discussed. It is believed that understanding degradation will contribute to driving the development of degradable packaging polyesters.

探讨与塑料食品包装相关的环境危害并讨论降解过程

每个国家都根据《巴黎协定》的目标选择了双碳（碳中和/排放峰值）政策，以满足人类发展的需求。据估计，全球已产生 800 万吨与该流行病有关的塑料垃圾，这凸显了停止或至少减少塑料污染的迫切需要。对可在堆肥或光照条件下分解的可降解聚合物的研究正变得越来越重要。本文概述了各种酯键可降解塑料聚合物，包括与水降解、光降解和生物降解有关的概念和机制。本文还回顾了重要的降解剂，并研究了目前商业中使用的几种酯键塑料聚合物。对这些酯键合可降解聚合物的局限性和潜在应用进行了比较和讨论。相信对降解的了解将有助于推动可降解包装聚酯的发展。

期刊介绍： The Journal of Environmental Chemical Engineering (JECE) serves as a platform for the dissemination of original and innovative research focusing on the advancement of environmentally-friendly, sustainable technologies. JECE emphasizes the transition towards a carbon-neutral circular economy and a self-sufficient bio-based economy. Topics covered include soil, water, wastewater, and air decontamination; pollution monitoring, prevention, and control; advanced analytics, sensors, impact and risk assessment methodologies in environmental chemical engineering; resource recovery (water, nutrients, materials, energy); industrial ecology; valorization of waste streams; waste management (including e-waste); climate-water-energy-food nexus; novel materials for environmental, chemical, and energy applications; sustainability and environmental safety; water digitalization, water data science, and machine learning; process integration and intensification; recent developments in green chemistry for synthesis, catalysis, and energy; and original research on contaminants of emerging concern, persistent chemicals, and priority substances, including microplastics, nanoplastics, nanomaterials, micropollutants, antimicrobial resistance genes, and emerging pathogens (viruses, bacteria, parasites) of environmental significance.
