Abstract:
Plant-assisted phytoremediation (PABR) has become widely employed in the restoration of contaminated soils. Such eco-friendly approach involves the use of various plant species or microorganisms working synergistically to convert contaminants into less toxic substances. One crucial aspect in studying the phytoremediation process is the potential reuse of the biomass involved. Typically, biomass derived from PABR is considered a waste due to uncertainties regarding heavy metal concentrations and the associated emissions risks. However, demonstrating that this biomass is viable and comparable to traditional biomass for energy conversion systems (e.g., gasification) would transform contaminated waste into a valuable resource.Gasification treatment of contaminated biomass has been proposed as an effective disposal method, and the TGA-DSC system (Thermo Gravimetric Analysis - Differential Scanning Calorimetry) can simulate these processes. In this study, a TGA-DSC analysis method has been developed to assess the emissions produced by two types of biomass obtained from a PABR campaign: poplar prunings (woody biomass) and Arundo Donax (herbaceous biomass). An ICP-MS analysis was conducted on the sampled metals to determine their concentrations.
