Identification et caractérisation des valorisations possibles des déchets de la filière horticulture-pépinière du Centre-Val de Loire

Abstract : As part of the CAP filière Horti-Pépi, a support program to boost the horticulture-nursery sector in the Centre-Val de Loire region, a study was carried out by VEGEPOLYS VALLEY to identify recovery processes for plastic and organic waste. This study was conducted in four steps. The first step provided background information and the second step identified the problems faced by producers in relation to the waste generated. Based on these results, a benchmark of four sectors was used to identify recovery processes, among which seven processes (composting, methanation, biorefineries, biochars, recovery of molecules of interest, mechanical recycling, and chemical recycling) were studied more specifically. Finally, information documents were written to communicate the results. Producers encounter difficulties in separating plastic components from biomass or in using the compost they produce. They also have problems with plastic waste, such as the difficulty of sorting and the significant soiling of plastics, which makes access to recycling more difficult. Among the solutions studied, composting seems to be the most accessible process for organic waste and most plastic recycling chains already exist. However, these processes do not solve all the problems identified. Solutions still need to be found to separate organic waste from plastic waste and to facilitate the cleaning of plastics.
