SABIC is a diversified manufacturing company, active in chemicals and intermediates, industrial polymers, fertilizers, and metals. It is the largest public company in Saudi Arabia, as listed in Tadawul, but the Saudi government still owns 70% of its shares. SABIC is also the largest listed company in the Middle East. Private shareholders are from Saudi Arabia and other countries of the six-nation Gulf Cooperation Council .SABIC was the world's fourth largest chemical producer in 2013. It is currently the second largest global ethylene glycol producer and is expected to top the list after the introduction of new projects. SABIC is the third largest polyethylene manufacturer, the fourth largest polyolefins manufacturer, and the fourth largest polypropylene manufacturer. SABIC is also the world’s largest producer of mono-ethylene glycol, MTBE, granular urea, polycarbonate, polyphenylene and polyether imide.In 2014, SABIC was ranked fourth in the world among chemical companies by Fortune Global 500, and the world’s 205th largest corporation. In 2010, SABIC grew to be the second largest diversified chemical company, or first when measured only by asset value.

Zelcor project aims at demonstrating the feasibility of transforming lignocellulose biorefinery 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 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 identify bio-products of commercial interest among lignins and humins multifunctional nanoparticles, 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.
