Utilization of Household Plastic Waste in Technologies with Final Biodegradation
Summary
Researchers developed a multi-stage processing method for polyethylene terephthalate and polystyrene household plastic waste, incorporating the materials into film-forming compositions used to encapsulate granular mineral fertilizers. The study confirmed that polymer shell residues safely biodegraded in soil after fertilizer dissolution, demonstrating a viable pathway for converting plastic waste into agricultural inputs.
We have carried out research on multi-stage handling of polyethylene terephthalate and polystyrene household waste. The method has been developed for both their safe utilization in manufacturing technologies and the use of encapsulated mineral fertilizers. The technical feasibility of implementing all stages of plastic waste processing has been defined: separate collection, creation of a film-forming composition, encapsulation of granular fertilizers. Our study has confirmed the safe biodegradation of polymer shell residues in the soil environment after the dissolution of the fertilizers. The proposed method of handling of these wastes is a method of their safe utilization.

Emerging Technologies for Converting Mixed Plastic Waste into Biodegradable Polymers
Scientists are developing new ways to turn mixed plastic waste (like food containers and shopping bags) into biodegradable materials that naturally break down instead of polluting the environment. This research review summarizes promising techniques that could help reduce the microplastics that end up in our food and water. If these methods can be made affordable and used widely, they could significantly cut plastic pollution and the health risks it poses to humans.
Emerging Technologies for Converting Mixed Plastic Waste into Biodegradable Polymers
Scientists are developing new ways to turn mixed plastic waste (like food containers and shopping bags all jumbled together) into materials that naturally break down in the environment, instead of lasting forever like regular plastic. This research review shows these emerging technologies could help solve our plastic pollution problem by preventing more microplastics from forming and contaminating our food and water. If these methods can be scaled up, they could transform how we handle plastic waste and reduce health risks from tiny plastic particles that are increasingly found in our bodies.
Unravelling the ecological ramifications of biodegradable microplastics in soil environment: A systematic review
Researchers reviewed 85 studies on biodegradable microplastics in soil, finding that when biodegradable plastics fail to fully break down they can disrupt soil structure, nutrient cycling, and microbial life in ways that depend heavily on concentration and plastic type. The review highlights that "biodegradable" plastics are not a simple fix for microplastic pollution in agricultural soils.
Investigating the sustainability of agricultural plastic products, combined influence of polymer characteristics and environmental conditions on microplastics aging
Researchers investigated how polymer characteristics and environmental conditions influence the photodegradation of agricultural plastic products in soil. The study examined low-density polyethylene microplastic degradation under different UV radiation and humidity conditions. The findings suggest that environmental factors significantly affect how agricultural plastics break down into microplastics, with implications for understanding long-term soil contamination from farming practices.
Identification of microplastics extracted from field soils amended with municipal biosolids
Researchers developed a method for extracting and identifying microplastics from agricultural soils that had been treated with municipal biosolids, a common fertilizer derived from wastewater treatment. They found a variety of plastic polymer types in the soil, confirming that biosolid application is a pathway for microplastic contamination of farmland. The study provides a reliable technique for tracking how microplastics cycle through agricultural environments.
