摘 要:In recent years, pressures on global environment and energy security have led to an increasing demand on renewable energy sources, and diversification of world’s energy supply. Among these resources the forest biomass residues(FBR) could exert an important role, since it is considered a renewable and CO2 neutral energy resource, and can potentially provide energy for heat, power and transport fuels. Taking into account the need to have information about the scenario of FBR to energy, and its implications on the Portuguese climate policy, it was initiated a study in order to characterize and quantify the FBR available from the Portuguese forest to energy purposes. In this study were presented the results of the amounts of forest biomass residues(FBR) available in Portugal, taking into account some conditioning related with land characteristics(e.g. slope). Comparing the FBR consumption for industrial thermal power plants it is possible to verify that the FBR available(1.91×106 ton(dry) year-1) in Portugal is enough to address the needs of industrial plants, but if the planned plants come into operation, the FBR available is no longer sufficient. Although considered a neutral carbon source, it is possible to notice that the FBR is a source which has impacts on air quality, due to the emissions of atmospheric pollutants. In order to understand the impacts of the chain of forest biomass to energy, the emissions of atmospheric pollutants associated with the logistics and the energetic conversion of forest biomass residues it is also presented.
