Dear Colleagues, Dr. Julia Valla and I would like to invite your contributions to our "Sustainable Biorefinery Processes" special issue in the MDPI journal Processes (ISSN 2227-9717; indexed in *SCIE* and *Scopus*; IF=1.279, http://www.mdpi.com/journal/processes). The deadline for submission is March 31, 2019. Analogous to the traditional refinery process that utilizes petroleum resources, biorefineries integrate various processes to produce fuels, power, heat, and value-added chemicals from biomass resources. However, the advantage of a biorefinery over the traditional petrochemical refinery is the processing of a renewable resource, namely biomass, to produce a variety of sustainable, green bio-products. Therefore, the produced liquid biofuels can be used for transportation purposes, the generated bio-energy can be used for power and heat, while high-value biochemicals can be used as feedstocks in pharmaceutical or other chemical processes. Although the concept of a biorefinery appears very attractive and promising from an environmental standpoint, there are still many challenges to be addressed before it is fully realized. Biomass feedstock availability, cost and diversity (energy crops, agricultural and forestry residues and waste, industrial and municipal waste, algae, triglycerides, sugar and starch, lignocellulosic feedstocks), process intensification and integration (thermochemical, biochemical, biological conversion of biomass along with upgrading and heat/power production processes), lifecycle analysis, market and economic viability, and even compatibility with current refinery infrastructure are all research areas that will play critical roles in the further development and feasibility of the biorefinery concept. This Special Issue on "Sustainable Biorefinery Processes" invites articles focused on research regarding the development of the biorefinery concept. Experimental, theoretical, and computational research on the biorefinery concept are all encouraged. Topics include, but are not limited to: * Type of biomass feedstock utilization * Innovations in biomass conversion and upgrading or retrofitting existing processes for bio-products (fuels, chemicals, power, and heat) * Process integration and intensification * Technoeconomic and lifecycle analysis * Novel modeling and simulation approaches http://www.mdpi.com/journal/processes/special_issues/Sustainable_Biorefinery_Processes We look forward to your submissions!
