Biodegradable PHA Plastics in Composting and Sewage Sludge Treatment Systems: A Green Revolution
AI summary Read the abstract
This chapter examines biodegradable PHA plastics in composting and sewage sludge treatment, evaluating their potential to reduce the microplastic burden that conventional plastics create in wastewater systems. If PHA bioplastics genuinely break down in real-world treatment conditions, they could replace conventional plastics that fragment into persistent microplastics contaminating soils and waterways.
Microplastics (MPs) pose a global environmental challenge due to their persistence and ability to accumulate and transport pollutants. This chapter discusses the MP sources and impacts in various environments. Wastewater treatment plants often serve as a sink for...

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.
Emerging and Advanced Technologies in Biodegradable Plastics for Sustainability
AI summary Read the abstract
Researchers reviewed advances in biodegradable plastics — including emerging technologies for faster and more complete breakdown — as a potential solution to growing microplastic contamination from conventional plastics. Replacing traditional plastics with materials that fully degrade could reduce the long-term buildup of plastic particles in soils, water, and living organisms.
Emerging and Advanced Technologies in Biodegradable Plastics for Sustainability
AI summary Read the abstract
Researchers reviewed advances in biodegradable plastics as a potential solution to the growing crisis of microplastic pollution, which accumulates in ecosystems and living organisms. While biodegradable alternatives show promise, the review highlights remaining challenges around performance, cost, and ensuring these materials actually break down safely under real-world conditions.
Biodegradable Bio-Based Plastics Toward Climate Change Mitigation
AI summary Read the abstract
Researchers assessed the potential of biodegradable, bio-based plastics as climate-friendly alternatives to fossil-fuel-derived plastics like polyethylene and polypropylene. Replacing conventional plastics with materials that break down naturally is one of the most promising long-term strategies for reducing the microplastic pollution that accumulates in soils, water, and living organisms.
Biodegradable Bio-Based Plastics Toward Climate Change Mitigation
AI summary Read the abstract
Researchers reviewed the development and applications of biodegradable, bio-based plastics — including PLA, PHA, and starch-based materials — as replacements for fossil-fuel-derived polyethylene, polypropylene, and PET in the context of climate change mitigation and plastic pollution reduction. Transitioning to genuinely biodegradable plastics could substantially reduce the long-term accumulation of persistent microplastic particles that degrade as conventional plastics fragment over decades to centuries.
