Investigation of plastic waste management in Thailand using material flow analysis
AI summary Read the abstract
This study used material flow analysis to model plastic waste in Thailand under two future scenarios, finding that even under Thailand's ambitious national roadmap, the 2027 target of 100% recycling of priority plastics is unlikely to be met, with a projected maximum recycling rate of 67%.
This study uses material flow analysis to investigate the amounts and pathways of municipal plastic waste (MPW) in Thailand. The aim is to understand the country's situation and investigate the effects of Thailand's Roadmap on Plastic Waste Management 2018-2030, which sets a goal for recycling 'target plastic waste' at 100% by 2027. The analysis was conducted using waste statistics between 2008 and 2020 and waste forecasts. Two scenarios of plastic waste management, the business-as-usual, and the national roadmap, were constructed for 2025 and 2030. In 2030, the annual MPW generation is projected to reach 2.19 Mt. Under the business-as-usual (BAU) scenario, the recycling and utilisation rate will be 32.3% of waste generated. About 30.3% of waste generated will not be treated properly and possibly leaked into the open environment. Under the roadmap scenario, the recycling and utilisation rate will increase to 98.4%, while 1.6% of waste generated will not be treated properly. The recycling rate for target plastic waste in 2027 could only reach 67.1% because plastic waste is required as fuel for waste incinerators and industries. With the roadmap fully implemented, certain effects can be foreseen for waste-to-energy and plastic industries. Findings from this study stress on the importance of holistic policy planning, efficient prioritising and allocating of waste as a resource, and cooperation from all sectors for sustainable plastic waste management.

Researchers conducted a global material flow analysis of plastic production and waste from 1950 to 2020, finding that plastic waste generation has consistently outpaced waste management capacity and currently produces approximately 60 million tonnes of mismanaged waste annually, with projections suggesting this could double by 2050 without robust policy interventions.

Researchers conducted sub-district-level material flow analysis across Indonesia to map where plastic waste is mismanaged most severely, moving beyond national aggregates to pinpoint local hotspots where leakage into the environment is highest and targeted intervention would have the greatest impact.
Pathways to zero plastic waste landfill: Progress toward plastic circularity in South Africa
AI summary Read the abstract
Researchers used material flow analysis and Sankey diagrams to track South Africa's plastic waste streams from 2017 to 2021, finding landfill disposal dropped from 74% to 39%, and identified improved waste collection and sorting as the highest-impact interventions needed to meet the 2050 zero-waste-to-landfill target.
Evaluating the Global Plastic Waste Management System with Markov Chain Material Flow Analysis
AI summary Read the abstract
Researchers used Markov chain material flow analysis to model global plastic waste scenarios, finding that current collection rates are the primary bottleneck in recycling chains and that even the most ambitious recycling targets would only reduce virgin waste generation by 34%, requiring a 2.5-fold increase in landfill and incineration capacity by 2050.
A high-resolution dynamic probabilistic material flow analysis of seven plastic polymers; A case study of Norway

Researchers assessed microplastic ingestion by wild boar, deer, and other terrestrial wildlife in a mixed agricultural-forested landscape, finding particles in gastrointestinal contents of most individuals sampled. The study demonstrates that microplastic contamination is not confined to aquatic systems but is pervasive in terrestrial food webs as well.
