Abstract:
The aim of the BeonNAT project is to select underused tree and shrub species in Europe with the potential to grow in marginal lands in Germany, Romania and Spain, and create added-value bio-based products following a cascade exploitation in biorefineries. Different biomass fractions (light, fine and coarse) using a sieving and blowing process have been obtained from 5 tree species and 2 shrub species with the aim of using the most appropriate raw material for each bioproduct. In this work, the fractions obtained have been characterised as a solid biofuel. In general, the use of biomass fractions to produce energy through combustion within the biorefinery concept outlined in the BeonNAT project may be feasible. The fraction with the best quality as solid biofuel is the coarse one due to its high wood content, although the use of the fine or light fractions within the proposed biorefinery is more likely. These fractions show higher concentrations of ash and some elements such as N, S or, in some cases, Cl than the coarse fraction, which can lead to more frequent cleaning of combustion devices, more frequent ash management and high NOx, SOx or HCl emissions
