Main description:

BTechPro2022 was organised by the Latvian State Institute of Wood Chemistry (LSIWC) and took place on April 27-29, 2022, in Riga, Latvia. The conference attracted young scientists from 9 countries and was devoted to Biorefinery Technologies and bio-based Products (BtechPro). According to the European Commission, Biorefinery can be broadly defined as the sustainable processing of biomass into a portfolio of marketable bio-based products, which could include the co-production of food and feed, materials and chemicals and bioenergy (power, heat/cold, fuels). Attention was paid not only to wood as raw material but also to a wide variety of biomass feedstock, pre-treatment and processing of them. Other topics covered at BTechPro2022: biomass-based materials; bioengineering technologies; synthesis of bio-based chemicals and polymers; characterisation of biorefinery products. The collected research articles cover current problems in biomass processing, starting from pre-treatment and bioengineering technologies to the synthesis and properties analysis of bio-based materials and chemicals. This edition will be of interest to scientists working on biorefinery topics.
