Degradation and control strategies for microplastics during aerobic composting: A review
AI summary
fold at 110 kV/mm, dramatically improving dielectric reliability. **Paper 101062** — Researchers fed clams (Ruditapes philippinarum) a diet of microalgae pre-exposed to bisphenol A analogues (BPAF, BPF, BPS), finding that dietary exposure induced oxidative stress, immune alterations, and epigenetic enzyme disruption in clam tissues even without detectable bioaccumulation of the bisphenols, highlighting a trophic transfer risk in marine food chains. **Paper 92989** — This study compared bacterial community changes in beach sediments surrounding HDPE plastic, biodegradable PHB, and bamboo materials over 258 days in the Mediterranean Sea, finding that all materials altered surrounding sediment microbial communities beyond their surface biofilms, with biodegradable materials recruiting more diverse degrading bacteria than conventional plastic. **Paper 112272** — Researchers evaluated silicon carbide (SiC) foam as a passive atmospheric sampler for PAHs, PCBs, and pesticides, finding it consistently outperformed standard XAD-2 resin at capturing both particulate and polar compounds, with carbon or carbon nanotube grafting further improving adsorption of volatile pollutants. **Paper 102799** — This meta-analysis of 203 studies on China's Loess Plateau found that combined plastic-and-straw dual mulching (SPM) outperformed single mulching methods in improving crop yield and water use efficiency across diverse temperature and rainfall conditions, while also demonstrating greater long-term green development potential than plastic mulching alone.

Microplastics in MSW-derived compost: release rate, characteristics, ecological risks, and mitigation strategies for sustainable agriculture
AI summary Read the abstract
Compost made from household trash often contains tiny plastic bits called microplastics, and surprisingly, the compost from industrial facilities had even more plastic contamination than the raw waste it started from. Since this compost gets spread on farm fields, these plastic fragments can build up in the soil where our food grows. The good news: simply sorting out plastic from food/organic waste before composting (rather than mixing everything together) dramatically cuts down on this contamination, suggesting better recycling habits at home and in waste facilities could help keep microplastics out of our agricultural system.
Microplastics in Composts, Digestates and Food Wastes: A Review
AI summary Read the abstract
Researchers reviewed microplastic contamination in composts, digestates, and food wastes, finding that plastic packaging mixed into food waste streams may inadvertently introduce microplastics into agricultural soils during composting or anaerobic digestion. The authors highlight critical research gaps and call for harmonized methods to better assess this potential pathway of soil microplastic contamination.
Microbial Biodegradation of Plastics and Microplastics: Recent Development
AI summary Read the abstract
Researchers reviewed recent advances in microbial biodegradation of plastics and microplastics, identifying key bacterial and fungal species capable of breaking down synthetic polymers and highlighting the biological mechanisms that could underpin scalable plastic waste remediation strategies.
Effect of Ventilation Modes on Microplastic Flow During Perishable Waste Composting
AI summary Read the abstract
Researchers investigated how four ventilation methods affect microplastic distribution during perishable waste composting, finding that composting reduced extractable MPs in the solid product by 73–84%, with most MPs migrating to leachate and composting time being the strongest influencing factor. This matters because MP migration into leachate means contaminated liquid can carry plastics into soils and waterways if not properly managed during this widely used organic waste treatment process.
Role of Microorganisms in Biodegradation of Microplastics
AI summary Read the abstract
Researchers examine how microorganisms degrade common microplastic polymers including polyethylene, polypropylene, PVC, and PET, reviewing the enzymatic and metabolic pathways bacteria and fungi use to break down these persistent materials and the potential for harnessing microbial activity as a biodegradation strategy.
