A Study on the Trend of Domestic Waste Generation and the Recognition of Recycling Priorities in Korea
This South Korean study examined trends in household waste generation and public recognition of recycling in the context of sustainable development goals and circular economy policy. Understanding recycling behavior and waste generation trends is important for reducing the plastic waste that eventually breaks down into microplastics.
Rheology of Recycled PET
This review examines how recycling changes the physical properties of PET plastic, the material used in most beverage bottles. Each recycling cycle degrades the polymer chains, weakening the material's mechanical and flow properties. Understanding PET degradation through recycling is relevant because improperly recycled plastic contributes to microplastic generation in the environment.

This review examined different strategies for reusing polyethylene terephthalate (PET) water bottles, highlighting their significant carbon footprint and waste generation while exploring sustainable recycling and repurposing approaches to reduce plastic pollution.
New Policy Framework for Effective Managing Microplastic in Circular System Form Plastic Product Manufacturing to Waste Treatment Facility
Researchers proposed a new policy framework for microplastic management by analyzing the full circular system of plastic -- from raw material production through consumption to waste treatment -- and examining microplastic waste at the final disposal stage. Applying the framework to the Korean waste management system demonstrated that the proposed circular system approach improves upon current microplastic management schemes.
Research on Plastic Recycling from a Global Perspective and PET Recycling Schemes in Hong Kong
This review examines global plastic production, environmental impacts, and recycling systems, comparing approaches in Hong Kong, Taiwan, and Germany, and finding that Hong Kong's low recycling rate and landfill-dependent system contrasts sharply with Taiwan's high recovery rates and Germany's strict classification and processing infrastructure. The study identifies structural and logistical barriers limiting PET and broader plastic recycling in emerging economies.

This review examined chemical and mechanical recycling technologies for polyethylene terephthalate (PET) waste, comparing glycolysis, methanolysis, hydrolysis, and enzymatic depolymerization routes in terms of yield, product purity, and scalability, and highlighting pathways most suitable for circular economy applications.
Sustainable Management of Microplastic Pollutions from PET Bottles: Overview and Mitigation Strategies
Researchers reviewed the environmental impact of PET bottle degradation and strategies for managing the resulting microplastic pollution. The study highlights that PET bottle usage continues to grow, and its breakdown releases low-molecular-weight compounds and microplastics, while outlining mitigation approaches including improved recycling and waste management practices.
Assessing the Selection of PET Recycling Optionsin Japan: Multi-Criteria Decision Analysis
This study examines PET plastic recycling options in Japan using a multi-criteria decision analysis (MCDA) framework, set against the global context in which only 9% of plastic waste is recycled and 22% bypasses proper waste management. The analysis evaluates competing recycling pathways to identify the most sustainable and economically viable approaches for managing Japan's PET waste streams.
Beyond processing methods: the impact of the drying technique on PET performance
This study investigated how different drying techniques affect PET polymer properties during recycling, finding that improper moisture removal causes hydrolytic degradation at high processing temperatures, with implications for maintaining material quality in circular economy PET recycling streams.
Process parameter optimization for waste polyethylene terephthalate bottle depolymerization using neutral hydrolysis
Researchers optimized process parameters for the neutral hydrolysis depolymerization of waste polyethylene terephthalate (PET) bottles as a chemical recycling strategy to address growing plastic waste accumulation in landfills. The study identified key conditions that improve depolymerization efficiency, offering a pathway to recover high-quality monomers from post-consumer PET.
Enhanced Methanolysis of Waste PET for Sustainable Production of Dimethyl Terephthalate and Cyclic Arylboronic Esters
Researchers developed a method using boric acid to improve the chemical recycling of waste PET plastic via methanolysis, producing high-purity monomers that can be used in new plastic production. More efficient PET recycling reduces the amount of plastic waste that breaks down into microplastics in the environment.
