Description
Summary:•Urban forestry and urban greening are potential energy suppliers.•Urban forests will contribute to the bioenergy development in Asturias (Spain).•Wood from urban forests can replace fossil fuels in thermal and power applications.•A pellet plant uses 51ktyear−1 of wood residues from the studied area. Nowadays, high-density population in urban areas coexist with rural industrial zones, such is the case of the Central Metropolitan Area (CMA) of the Principality of Asturias (NW Spain) where 78% of the population of the region lives, and where 14% of the Asturian forests are located. This situation generates significant amounts of forest residues from management activities. The urban forests of the CMA generate large amounts of biomass residues, consisting primarily of branches from cleaning, thinning and felling operations. The available residues are suitable as biomass feedstock considering techno-economical and environmental constraints. The method used to choose the most suitable location for a pellet plant to process available residues is based on GIS software. This study has assessed the available biomass feedstock and the management implications to maximize the availability of forest residues for bioenergy. The calculated potential amount of wood residue is 92.7dryktyear−1, equivalent to 920.1TJyear−1. The municipality of Corvera has been proposed as the most suitable CMA location for a pellet plant. The plant could reach an annual pellet production capacity of 51kt, equivalent to 32MWth of fuel output.
