Mapping the feasibility of lignocellulosic biorefinery routesthe relevance of system modelling in life cycle assessment

Résumé

The defossilization of the chemical industry, together with negative emission technologies like carbon capture and storage and carbon capture and utilization have been defined as essential contributors to curb the climate crisis. To reach climate goals, it will also be necessary to support the sustainable development of biorefining pathways. The objective of this thesis is to determine the environmental weaknesses and strengths of second generation biorefineries. The analysis of different renewable carbon opportunities to reach climate neutrality goals and objectives beyond decarbonization was achieved though the life cycle assessment methodology. Studying different modelling systems allowed to support the consistent development of recommendations and best practices in regulations and standards of biorefineries.
