Agrocomposit, FHNW School of Life Sciences

As part of the circular economy, the recycling of biogenic residues can contribute to closing material and energy cycles. In the Agrocomposit project, the focus is on fertilisers and soil conditioners that are produced by adding biochar to composts ("agrocomposites").

In Hungary, Norway and Switzerland, regionally available biogenic residues are converted into high-quality resources. With the help of partners active in biogenic residue treatment and agriculture, resulting agrocomposites will be investigated for their agronomic benefits, soil quality, and environmental impacts.

The agrocomposites are analyzed for nutrient and carbon and pollutant contents. Promising agrocomposites are subsequently tested in pot and field trials by Agroscope with regard to their agricultural and ecological benefits. FHNW will apply life cycle assessment, cost-effectiveness calculations, and environmental risk assessments to compare agrocomposites against other fertilizer and biogenic residue management options.
