Moreira Vilar, María TeresaBello Ould Amer, Sara2022-12-222022-12-222022http://hdl.handle.net/10347/29623The 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.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/life cycle assessmentbiorefinerywoodcarbon capture and storagecapture and utilizationbioproductsbiofuelsenzymesMaterias::Investigación::33 Ciencias tecnológicas::3303 ingeniería y tecnología químicas::330303 Procesos químicosMaterias::Investigación::33 Ciencias tecnológicas::3308 Ingeniería y tecnología del medio ambiente::330801 Control de la contaminación atmosféricaMaterias::Investigación::33 Ciencias tecnológicas::3308 Ingeniería y tecnología del medio ambiente::330804 Ingeniería de la contaminacióndoctoral thesisopen access
