Project Overview

Description of ZELCOR – Zero Waste Ligno-Cellulosic Biorefineries by Integrated Lignin Valorisation

Zelcor project aims at demonstrating the feasibility of transforming lignocellulosebiorefinery recalcitrant side streams into high added-value biobased products, including fine chemicals. Its concept is to combine chemical and enzymatic catalysis with insects-based biological conversion, within a biorefinery integrated approach. The project is conceived to avoid waste production by recycling waste bio-based products and to improve the sustainability of existing second generation biorefineries. It addresses three types of recalcitrant raw materials: lignocellulosic residues from ethanol production, lignins dissolved during pulping process and lignin-like humins formed by sugars conversion. Enzymatic and process engineering will be implemented to design efficient conversion routes and permit technological breakthroughs.

A transversal platform for the characterisation of biomolecules will be settled to identifybio-products of commercial interest among lignins and humins multifunctionalnanoparticles, phenolic antioxidants, insects-based chitosans and aromatic chemical intermediates. Thanks to this platform, Zelcor will enhance knowledge of the structure-function relationships and the mechanisms involved in recalcitrant raw materials catalytic depolymerisation and bioconversion. Demonstration of the approach feasibility will be performed by process scaling-up, formulation of end-product prototypes and value chain sustainability and safety assessment.

The presence of industrial partners all along the value chains, from lignocellulosic feedstock to end products, will facilitate demonstration activities and technological transfers. With this strong industry drive, Zelcor will lead to large scale production of biomolecules for cosmetics, packaging and chemical industry, as well as novel biocatalysts. Zelcor is a 6.7M€ collaborative project, 49% of which for SMEs (43% EC grant). It gathers 18 organisations from 8 countries, including 6 academia, 8 SMEs, and 3 corporations.
