Reducing the Plastic Footprint in Agriculture: The Cross-Border Project AgriRePlas as a Case Study in the Upper Rhine Valley

The advantages of plastic products in modern agriculture are well-documented. Greenhouse films and tunnels enable temperature control, while ground coverings, like films and nonwovens, are used to regulate evaporation, soil temperature, weeds and pests. These applications help to save water and agrochemicals, increase crop yields and extend the growing season. However, the use of plastics in agricultural fields also poses risks, such as the release and accumulation of persistent (micro)plastics in the environment. This could have negative effects on soil physics, biogeochemistry, microorganisms, plants and animals. The cross-border project AgriRePlas aims to evaluate the current use of plastics in agriculture, their potential leakage pathways and the management of used materials. By bringing together stakeholders along the entire value chain, including growers, plastic producers and manufacturers, retailers, as well as collection and recycling companies, the project plans to develop measures to improve plastic use and minimize environmental impacts in three agricultural sectors. In close collaboration with public administrations, growers’ associations, agricultural schools, research centers and academic partners, AgriRePlas will promote multiple-use and deposit-refund systems, particularly for packaging. Recycling rates of used agricultural plastics will be increased through improved information, coordination of logistics and optimization of material quality and quantity. Plastic products currently used in agricultural production are screened for applications with a high risk of loss and leakage. Wherever appropriate, biodegradable alternatives are being identified. Existing biodegradable products are tested in real-world field trials together with farmers and accompanied by scientific monitoring. Complementary studies will examine plastic contamination from conventional products and the behavior, degradation and effects of biodegradable alternatives in soil, with particular consideration of regional climatic and conditions. Information and knowledge transfer play a central role in the project, aiming to strengthen plastic literacy among consortium members and stakeholders. All generated data and results will be made publicly available in German, French and English to support practitioners and policymakers in the Upper Rhine region and beyond.
