In general terms, renewable energy sources are characterized by their decentralized availability, ability to quickly self-regenerate, and the reduced environmental impacts resulting from their use. The conversion of forest biomass into energy will make it possible to transform waste into raw material for the energy industry while promoting forest management. Reducing the forest's fuel load will be responsible for reducing the intensity of forest fires. In this context, biorefineries significantly prevent rural fire risks by addressing two important aspects: fuel management and renewable energy generation. based on these premises, this study aims to assess the potential for implementing a biorefinery in the Centro Interior region. The amounts of available residual biomass were calculated based on data from the national forest inventory, carried out in 2015.For the municipalities with higher residual biomass production, a decision support system based on GIS and Multicriteria Decision-making was used to select sites suitable for locating a forest biorefinery and provides a valuable reference for decision-makers. The combination of MCDM and GIS methods can, therefore, be seen as a powerful tool for solving power planning problems. The most relevant areas, in terms of land occupation of the three forest species considered, are mainly found in the south of the region under study. The area under study has the potential to generate an annual flow of residual biomass of 269,024 tons per year, with maritime pine harvesting accounting for 80% of this flow. However, around 88,193 tons of the annual flow of residual biomass (33%) are found in regions that are difficult to access, and the costs may make exploration unviable in economic terms. According to the study carried out, we consider that the implementation of the biorefinery will be located in the industrial area of the municipality of Oleiros.
