Recovery of olive oil by-products through bio/hydro chars production for agricultural soil fertilization and environment preservation




FERTICHAR will use an innovative case-study approach that offers the best conditions work and exchanges to scientists and locally relevant actors concerned by olive mill wastes fate and agricultural production systems, under various pedoclimatic conditions and socioeconomic settings in Europe and North Africa. The adopted methodology will consist firstly on the impregnation of OSW by OMW and then its thermal treatment by two procedures, i.e., slow pyrolysis and thermal carbonization in order to produce nutrients-enriched biochars/hydrochars, respectively. Then, these two kinds of derived-solid residues will be used as amendments for olive trees (field assays) and high added economical values crops (tomatoes in lab experiments). Their positive effects on these plants growth, nutrients release, carbon sequestration and organic pollutants retention will be experimentally and numerically assessed in both Europe and North Africa. For maximizing the project socio-economic impacts, the main concerned stakeholders will be implicated from the beginning of the project. Exchange of researchers and students will be the core activities for innovation transfer. Specific tools and actions (website, social media channels, conferences...) will be used for the exploitation, dissemination and communication of the main project outputs to stakeholders and scientists.
