Abstract(s)

ABSTRACT: The use of biomass feedstock for bioenergy production has increased in recent years. In the context of a circular economy, wastes such as municipal solid wastes and industrial wastes (namely by-products from agrofood wastes, agro-livestock wastes and sewage sludge) have been tested as new feedstocks of biomass origin. However, the presence of some inorganic contaminants in these new feedstocks might be problematic for thermochemical and biochemical conversion processes. Wavelength Dispersive X-Ray Fluorescence (WD-XRF) spectrometry is an easy and fast technique that uses only a small amount of sample, presenting a low contamination risk and is a non-destructive methodology. Thus, if potential contaminants are identified, then samples remain available for subsequent analysis.
