Socio-Economic Contributions of Informal Waste Pickers to Urban Waste Management

This study examines the socio-economic contributions of informal waste pickers to urban waste management systems, finding they prevent significant recyclable materials from reaching landfills, reduce greenhouse gas emissions, and sustain livelihoods for millions of urban poor. The authors argue for formalization pathways that integrate waste pickers into municipal systems while preserving their economic autonomy.

Decision Analysis Approaches on the Collection Methods of Polyethylene Terephthalate Waste

This study compared three decision-analysis methods (AHP, TOPSIS, and VIKOR) to rank PET plastic bottle cap collection strategies and found that threshold-based collection (collecting caps only above a weight or volume threshold) is the most cost-effective and practical approach. Although this paper focuses on PET waste management strategy rather than microplastic contamination directly, improving PET collection efficiency is an important upstream step for reducing the plastic debris that ultimately fragments into microplastics in the environment.

A Reliable and Robust Deep Learning Model for Effective Recyclable Waste Classification

Researchers developed a deep learning computer model that can sort waste into six categories, including plastic, with 95% accuracy. While this is a waste management technology rather than a health study, better automated waste sorting could help keep more plastics out of the environment where they break down into microplastics. Improved recycling through AI-powered sorting is one practical step toward reducing the microplastic pollution that eventually reaches people.

Global Plastic Pollution and Informal Waste Pickers

This review examines how plastic pollution disproportionately affects communities in the Global South, where plastic consumption has risen sharply while waste management infrastructure remains underfunded or nonexistent. The study highlights the role of approximately 20 million informal waste workers who already recover and recycle significant quantities of plastic but often work under hazardous conditions without recognition or support. Evidence indicates that integrating these informal workers into formal waste management systems could be an effective strategy for reducing plastic pollution while improving livelihoods.
