Recycling and Risk - UPR Recyclage et risque

Internal Research Unit (UPR) PERSYST Department

Recycling of organic waste (so-called residual organic products or ROPs) can contribute to the design of agro-ecological production systems that perform well on both an economic and an environmental level. It also serves to make use of that waste as part of a circular economy.

Within this context, UR Recycling and Risk studies nutrient and contminant fluxes on various interlinked scales (from molecule to territory), so as to assess the agronomic and environmental impacts of ROP recycling. The aim of its research is to come up with solutions, methods or models so as to recycle waste via agricultural practices whose agro-environmental risks are controlled, making optimum use of the capacity of the soil and plants to purify that waste and weighing up the complementarities or clashes between various types of ROP uses on a territory level.
