The use of plastic products has increased significantly due to their versatility, ease of manufacture, and affordability. However, the excessive production and disposal of plastics have led to environmental concerns. Packaging and construction are the largest end-use markets for plastics in the EU. Agriculture is another major user, with plastic products like mulching films, controlled-release fertilizers, and tree guards being widely used. While these products offer benefits like water conservation, weed control, and increased yields, they also pose risks of soil pollution and environmental contamination. The majority of agricultural plastics are not collected or recycled, leading to improper disposal and landfilling. Other plastic products, such as turf nets and infills, are not biodegradable and difficult to recover for recycling. To address these issues, SOUL aims to develop novel, biodegradable materials with high renewable content. The consortium partners will focus on producing new materials, transforming existing plastic products, and developing sustainable end-of-life solutions. By addressing waste management, reducing carbon footprints, and preventing soil contamination, SOUL seeks to contribute to a more sustainable and circular plastic economy. SOUL will deploy at TRL8, with a circular bioeconomy and multi-actor approach, a complete value chain to produce 11 innovative bio-based and biodegradable in soil product solutions meeting high market demand, by the combination of 3 building blocks and 8 technologies, reaching solutions with a 95% of Renewable Raw Materials while ensuring a platform able to respond to the different application needs.
