Multi-criteria evaluation and optimizing of raw materials recycling

Recycling organic waste products (OWP) in agriculture can improve the chemical, physical, and biological fertility of soils. This recycling can also allow for the substitution of mineral fertilizers and/or an increase in agricultural production. However, various contaminants (pathogens, microplastics, organic and inorganic) can be applied to soils during this recycling process and accumulate in the soil and/or be transferred to crops and/or water, with potential ecotoxicological effects. Other environmental impacts can occur, such as nitrate leaching and gaseous emissions (ammonia, greenhouse gases, volatile organic compounds). All effects vary depending on (i) the characteristics of the OWP applied, in relation to its origin and potential treatment, (ii) the soil and climate conditions, and (iii) the cropping system in which this recycling takes place. Furthermore, the potential use of OWP depends on its local availability within the territories.

Objectives

The objective of this research area is to evaluate material recycling using a multi-criteria framework in order to contribute to its optimization. The focus is on two areas of study: organic waste products and technosols, from the plot level to the territory level. These two areas of study are investigated through separate research projects due to their specific characteristics, although links exist, as organic waste products are often used in the construction of technosols.
