Identifiant : 354-4BIOLIVE
Type de projet : Development and innovation oriented (research) project

Présentation
The specific objectives (O1-O4) of the proposal are :
* O1 : Identification of high value ingredients in olive mill wastes and extraction for biostimulants and biofertilizers. Olive mill wastewater (OMWW), olive mill solid wastes (OMSW) and pomaces (POM), selected as the main residues of olive-oil chain production, will be characterized to optimize their further reuse. High-value compounds will be identified and extracted, taking into account their physico-chemical properties.
* O2 : Use of lignocellulosic fraction as biostimulant and biofertilizer. Water soluble Lignin (WSL) obtained from olive mill solid wastes and pomaces will be processed to obtain a bioactive substance with humic-like effects for stimulating plant development and resistance to stress. Solid lignin will be purified, and lignin nanoparticles (LN) will be prepared and used as carriers for bioactive compounds (LN-PC) obtained in O1 to realize an efficient molecular vehicle to improve plant absorption. Lignin will also be used to produce biopolymeric compounds (BPC) with enhanced controlled-release capacities, to allocate bioactive compounds and nutrients, with the goal of obtaining slow-release materials to be used as biofertilizers and eventually as biostimulants.
* O3 : Valorisation of residual biomass for biogas and soil organic fertilizer production. The residual biomass after the extraction of high-value bioproducts (O1 and O2) will be characterized and investigated as potential feedstock for anaerobic digestion and co-digestion, in order to produce biogas. In addition, the anaerobic digestion effluent (digestate) will be analysed to evaluate the potential benefits of its agricultural reuse as organic fertilizer and soil conditioner.
* O4 : Evaluation of social, economic and environmental impacts in the Mediterranean area. Potential socioeconomic and environmental impacts of the innovative bioproducts obtained will be evaluated by developing a methodology for the assessment of acceptability, feasibility and accessibility of the developed processes and bioproducts in comparison with current strategies and methods. 4BIOLIVE - Production of Biostimulants, Biofertilizers, Biopolymer and Bioenergy from OLIVE-oil chain residues and by-products
