During the development of biodegradable products, soil ecotoxicity after complete material disintegration is a critical factor. Within the MAGICBIOMAT project, this aspect is fully integrated into the research design 
The ecotoxicity of the polymer blends developed will be evaluated at IPC Formation (https://www.ct-ipc.com/) using several plant species. To ensure conditions that closely reflect real-life scenarios, contaminated soil must first be generated through the complete disintegration of the materials under pilot-scale composting conditions.
For this purpose, organic biowaste is required to produce the compost. Terra Preta association, active in biodiversity protection and organic waste treatment in the Clermont-Ferrand metropolitan area, provided the IPC laboratory with the necessary material. In total, it is more than 100 kg of organic waste which were collected and mixed in the laboratory following a precise protocol 
The composting process is currently underway. In three months, the resulting contaminated soil will be recovered and used for ecotoxicity testing.
This collaboration strengthens the connection between R&D activities focused on the sustainability of plastic materials and real-world field practices supported by committed local stakeholders
