INSOIL
Safe bio-based and biodegradable IN-SOIL solutions for circular and sustainable crop production
Expected results:
Agricultural plastics used in crop production often remain in the soil after application. Persistent plastic accumulation leads to the release of microplastics and toxic substances causing soil pollution and threatening ecosystems. Single-use plastics are of particular concern, as they are impractical to recover. To mitigate these impacts, the EU aims by 2030 to
- reduce by 20% fossil-based plastic production and
- cut by 30% microplastic releases into the environment.
Bio-based alternatives are emerging in response, as they can safely biodegrade in soil. However, further development is needed to produce biodegradable technologies that are high-performing and cost-effective. INSOIL tackles agricultural plastic pollution by developing three families of fully bio-based, safe, in-soil biodegradable products in the form of mulch films, plant guards and controlled-release fertilisers (CRFs) to replace widespread single-use plastics in crop production. These three product families will be based on sustainable PHA combined with tailored additives (MFCs, modified lignins), enabling programmed biodegradation suited to specific climates and crops. They will be enriched with active bioproducts (organic NPK, biostimulants, bio-based PPPs) to enhance their functionality, value and adoption. INSOIL agriproducts will be field validated with end users (TRL8) across relevant vegetables and fruit trees in Southern and Northern Europe. SSbD experts will ensure compliance, policy recommendations will advance relevant regulations and standards, and circular business models will secure market acceptance. By 2035, INSOIL agriproduct commercialisation will reduce (micro)plastic release (5,820 tonnes) and agrochemical use (4,000 tonnes), cutting CO2 emissions by 16,000 tonnes, while generating €17.4 M in savings for farmers. INSOIL will thus contribute to a secure food supply and boost the sustainability, circularity, autonomy and competitiveness of EU bio-based value chains.
