ClearAgricultural Waste Management for Food Security and Sustainability
This review examines how agricultural waste, including crop residues, animal manure, and food processing by-products, can be transformed into valuable resources through composting, biogas production, and biochar application. The authors highlight that new technologies like AI and IoT are helping optimize these recycling processes. The findings are relevant to microplastic concerns because improper agricultural waste management contributes to soil and water pollution, including plastic contamination from fertilizer coatings and mulch films.
Lignocellulosic Agricultural Waste Valorization to Obtain Valuable Products: An Overview
This review covers methods for turning agricultural plant waste into valuable products like biofuels, bioplastics, and animal feed. While not directly about microplastics, it is relevant because developing bioplastics from plant waste could reduce dependence on petroleum-based plastics that break down into microplastics. These sustainable alternatives could help decrease the amount of microplastic pollution entering the environment and food chain.
Sustainable energy from waste organic matters via efficient microbial processes
This review examined the potential for converting waste organic matter, including microplastics, from water and soil sources into sustainable energy through microbial processes. Researchers discussed how anaerobic digestion and other wastewater treatment technologies can help address the environmental challenge of organic waste while producing useful bioenergy and other primary metabolites.

This review examines microbial degradation of plastics in the environment, discussing how environmental breakdown of plastics generates microplastic particles that accumulate in plants and animals and cause metabolic disruptions, while exploring the potential of microorganisms to break down plastic polymers.
Distribution characteristics of microplastics in typical organic solid wastes and their biologically treated products
Researchers extracted and characterized microplastics from food waste, livestock manure, sludge, and their composted or digested products, finding MPs in all organic waste types with concentrations varying by matrix. The study highlights organic waste management pathways as an understudied route for microplastic transfer to agricultural soils.
Microplastics in Agricultural Soils: An Emerging Threat to Soil Health, Microbial Ecology, Crop Productivity, and Food Safety
This review examines how microplastics accumulate in agricultural soils from sources like plastic mulch, sewage sludge, and atmospheric deposition. Researchers found that these particles can disrupt soil microbial communities, harm plant health, and potentially enter the human food chain. The study highlights the urgent need for mitigation strategies to address this growing but often overlooked form of pollution in farmland.
Incarnation of bioplastics: recuperation of plastic pollution
This review explored bioplastics as eco-friendly alternatives to petroleum-based plastics, examining their production from agricultural and kitchen waste products and their potential for microbial decomposition to help reduce plastic pollution.
Marine Environmental Plastic Pollution: Mitigation by Microorganism Degradation and Recycling Valorization
This review examines how microorganisms can degrade marine plastic pollution through enzymatic processes and how recycling technologies can recover value from plastic waste. Researchers surveyed various microbial species capable of breaking down common plastics and assessed the effectiveness of different recycling approaches. The study suggests that combining biological degradation with improved recycling infrastructure could help address the growing crisis of ocean plastic pollution.
Agricultural Plastic Waste Management
This article describes a European research project on recycling agricultural plastic waste including mulch films, packaging, and greenhouse covers, which are significant sources of microplastic contamination in farmland soils. The project developed innovative biodegradation routes as an alternative to landfill disposal.
Plastic Pollution in Agriculture as a Threat to Food Security, the Ecosystem, and the Environment: An Overview
This review examines how plastic products used in agriculture -- from mulch films to greenhouse covers -- contribute to microplastic pollution in soil, water, and crops. While plastics help boost crop production and food quality, their breakdown releases microplastics that can be taken up by plants and enter the food chain. The paper discusses strategies to reduce plastic pollution in farming, which is important because agricultural microplastics represent a direct pathway to human dietary exposure.
Microplastics in composts, digestates, and food wastes: A review
This review examines how food waste composting and recycling processes can introduce microplastics into agricultural soil. When food waste mixed with plastic packaging is composted or processed through anaerobic digestion, microplastic fragments can end up in the soil amendments spread on farmland. The findings highlight an overlooked pathway by which microplastics enter the food chain, as crops grown in contaminated compost may absorb or accumulate plastic particles.
Activities of Microplastics (MPs) in Agricultural Soil: A Review of MPs Pollution from the Perspective of Agricultural Ecosystems
This review summarizes the origins, migration, and fate of microplastics in agricultural soil ecosystems, identifying plastic mulch film, irrigation water, and organic fertilizers as major sources. The study highlights that microplastic accumulation in farmland can affect soil structure, microbial communities, and crop growth, with potential implications for food safety through the terrestrial food chain.
A comprehensive review of food waste valorization for the sustainable management of global food waste
This review examines methods for turning food waste into valuable products as part of sustainable waste management. While not directly about microplastics, the topic is relevant because food waste and plastic waste are often mixed together in waste streams, and food packaging is a major source of microplastic contamination. Better food waste management could help reduce the spread of microplastics that often accompany food waste into the environment.

Towards a Sustainable Future: Advancing an Integrated Approach for the Recycling and Valorization of Agricultural Plastics
This review surveys current methods for recycling and valorizing agricultural plastics—films, mulches, and greenhouse covers—highlighting that inadequate end-of-life management leads to soil and water contamination and eventual microplastic formation. A more integrated, circular approach to agricultural plastic design and disposal is needed to prevent these materials from fragmenting into persistent environmental pollutants.
Significance of Microplastics in Agricultural Soil
This review examines the significance of microplastic contamination in agricultural soils, estimating it contributes approximately 20% of total plastic pollution in terrestrial ecosystems. Microplastics enter farmland through irrigation, mulch, and sewage sludge, and can be transported deeper into soil by plant roots and soil organisms. The accumulation of microplastics in agricultural land poses risks to soil health and the food grown in it.
Microplastics in agricultural soils: sources, impacts, and mitigation strategies
This review summarizes how microplastics enter agricultural soils through wastewater irrigation, plastic mulch breakdown, and atmospheric deposition, where they alter soil structure, microbial communities, and water retention.
