Prospective Scenarios for Addressing the Agricultural Plastic Waste Issue: Results of a Territorial Analysis
Summary
A study on agricultural plastic waste assessed prospective management scenarios combining stakeholder input with life cycle analysis to identify sustainable pathways for reducing farm plastic pollution. Results highlighted the need for integrated approaches spanning plastic reduction, reuse, and improved collection systems.
Agricultural activities have been positively affected by the use of plastic products, but this has resulted in the production of plastic waste and led to an increase in environmental pollution. To continue benefiting from the use of plastics but addressing at the same time the environmental issue, two strategies seem viable: the development of technologies for extending plastics lifespan and the gradual replacement of traditional non-biodegradable materials by biodegradable ones, at least for some products. This study focuses on a territorial analysis, performed using a Geographic Information System (GIS) in an agricultural area of the Apulia region (southern Italy). Areas of agricultural plastic waste production were identified through land-use maps. The application of plastic waste indices to different crop types and plastic products allowed quantifying and georeferencing actual plastic waste production. From this actual visualization, the other strategies were obtained by properly managing the indices. Two improved scenarios were obtained, the first consisted of extending the lifespan of some plastics, and the second entailed the introduction of some biodegradable alternatives. About 11,103 tons of agricultural plastic waste are yearly produced in the area and 7450 tons come from covering films. Lifespan extension would reduce the annual waste amount by about 25%, while more alternative products are needed to achieve significant results in the second scenario.

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.
Employing a systems approach to unravelling the complexities of the agricultural plastics value chain
Researchers used a systems analysis approach to map the full lifecycle of plastics used in agriculture — from production to disposal — and found that while these materials boost crop yields, they create serious sustainability problems including microplastic accumulation in soil and chemical leaching. The study identifies critical gaps in data, policy, and infrastructure needed to manage agricultural plastic waste and transition toward more sustainable alternatives.
Integrated Recycling and The Impact of Plastic Waste from Industry and Agriculture on The Environment
This review examined the environmental impacts of plastic waste from industrial and agricultural sources and assessed integrated recycling strategies for reducing those impacts. The paper discussed how plastic waste prevention, collection, and recycling can minimize pollution and climate contributions from the growing global plastic waste stream.
Agricultural plastics and environmental sustainability: Assessment and remediation strategies
This review examines the environmental and socioeconomic impacts of agricultural plastics including mulch films, irrigation pipes, and greenhouse covers, and evaluates management strategies such as recycling, composting, biodegradable alternatives, and circular economy models for reducing microplastic accumulation.
Management of agricultural plastic waste in Portugal to prevent microplastics
Researchers examined the management of agricultural plastic waste in Portugal, assessing how mismanagement of plastics used in farming has led to soil contamination with microplastics and identifying practices that reduce plastic fragmentation and environmental release. The study found gaps between best practices and actual farm-level waste management that result in preventable plastic accumulation in agricultural soils.
