ClearComposting as a Sustainable Solution for Organic Solid Waste Management: Current Practices and Potential Improvements
This systematic review of composting practices finds that technological advances like microbial inoculants and in-vessel systems have improved efficiency, but managing contaminants such as heavy metals and microplastics in compost remains a significant challenge. The presence of microplastics in organic waste streams threatens compost quality and can introduce plastic pollution into agricultural soils.
Electro-Composting: An Emerging Technology

Removal Potential of Microplastics in Organic Solid Wastes via Biological Treatment Approaches
This review examines biological treatment approaches — including composting, anaerobic digestion, and vermicomposting — for removing microplastics from organic solid wastes, finding that while these methods can reduce microplastic abundance, significant knowledge gaps remain about fragmentation and fate during treatment.
Composting of Organic Solid Waste of Municipal Origin: The Role of Research in Enhancing Its Sustainability
This review examines the role of composting in managing the organic fraction of municipal solid waste, highlighting both its benefits for material recovery and its challenges. Researchers found that issues such as the presence of microplastics and other toxic substances in compost can undermine the circularity of the process. The study suggests that continued research is needed to improve composting practices and reduce contaminant transfer to agricultural soils.
Review on advances in toxic pollutants remediation by solid waste composting and vermicomposting
Researchers review how composting and vermicomposting — using earthworms and microbes to break down organic waste — can neutralize heavy metals and persistent chemical pollutants in solid waste streams. Notably, earthworms have been found to break microplastics down into even smaller nanoplastics during digestion, raising new questions about whether vermicomposting spreads rather than eliminates plastic contamination.
Decentralized Composting of Food Waste: A Perspective on Scientific Knowledge
This review of home and community composting assesses performance parameters, compost quality, and environmental impacts based on current scientific literature. Home compost quality in terms of stability and maturity is comparable to industrial compost, though sanitization is not always achieved and temperature stratification in small composters remains a challenge.
Microplastics generation and concentration during mechanical-biological treatment of mixed municipal solid waste
Researchers found that mechanical-biological treatment of mixed municipal solid waste generates and concentrates microplastics across multiple processing stages, with the stabilized organic output containing significant microplastic loads — raising concerns about the use of this material as compost or soil amendment.
