Development of a flexible small-scale technology for the production of 2G Bioethanol from forest and agricultural biomass residues


By 2030, one of the ways of decarbonizing the transport sector is to bring advanced biofuels onto the market, with a minimum of 1% in 2025 and 3.5% in 2030 under the RED II Directive. To avoid future importations, it is essential that an industrial cluster appears in Portugal with the capacity to produce these biofuels, in particular 2G (second generation) Bioethanol.

In this context, BIOFLEXPOR project will be promoted by a consortium composed of Prio Bio (Lead Promoter), LNEG (non-business entity of the Research and Innovation System), Centro de Biomassa para a Energia (private non-profit association dedicated to research) and by Florecha (a business entity in the agricultural and forestry sector). By considering the high technical know-how of these entities, the project will aim to develop a small-scale technology for the production of 2G Bioethanol, which does not exist in the market, allowing a flexible pre-treatment of various agricultural and forest-based residual biomass, and thus promoting the circular bioeconomy.

BIOFLEXPOR technology will be initially studied at laboratory scale. The technological solutions will then be validated in relevant environment (TRL5), through the assembly and operation of a prototype with the integration of all unitary operations involved, simulating (1:15 scale) a commercial biorefinery of Bioethanol 2G. All the technology developed will be environmentally sustainable both in terms of GHG emissions and zero waste production (liquid or solid).

Project duration: 23/02/2021-22/02/2023; Co-funded by: Projetos de I&DT Empresas em Copromoção (Aviso 17/SI/2019).
