Rainbow colours of biobutanol
Biobutanol is a more efficient alternative to petrol than bioethanol and can be used as a partial or complete substitute for petrol in unmodified internal combustion engines. Sustainable production of the biobutanol depends on the used feedstock source and its pre-treatment methods, selected enhancing strategy of microorganism strain, acetone–butanol–ethanol fermentation effectiveness, and solvent recovery techniques. The aim of this project is to find the most optimal set of technological solutions for the production of biobutanol from agro-industrial by-products in a cost-effective manner in line with circular economy principles. Databases for raw materials (availability, pre-treatment, media, etc.), technological (extraction methods), and biotechnological solutions (microbial strains, cultivation methods and conditions) used for biobutanol production will be created. Using SWOT and multi-criteria analysis (MCA) the most appropriate sets of solutions will be identified from these databases. Each of these identified sets of solutions will be subjected to laboratory testing and a life cycle analysis (LCA) and economic assessment will be performed for the set with the best experimental results (higher biobutanol yield (mL/L/h), lower feedstock pre-treatment costs (EUR/t), etc.). Results will be used to strengthen intellectual property rights, further develop created technology, write a monography, prepare new project applications and new scientific publications, introduce entrepreneurs, society and students to the developed technology and prepare recommendations for legislators.
