Biomass and waste combustion as sustainable strategy for decarbonization
Valorisation of Gasification-Derived Biochars from Forest Biomass and Municipal Waste for CO2 Capture Applications
Short Introductive summary
Biochars were produced from forest biomass residues and municipal waste fractions through gasification and evaluated as sustainable adsorbents for CO? capture. Ten biochars with different physicochemical properties were generated from various feedstocks, including conifers, hardwoods, stone pine, holm oak, municipal organic fraction, and digestate-derived materials. The biochars were produced at 750 °C under controlled atmosphere conditions, yielding materials with carbon contents between 66% and 89% and surface areas ranging from 157 to 467 m²/g. CO? adsorption capacities ranged from 32 to 45 mg/g, consistent with non-activated carbonaceous materials. Biochars derived from single forest feedstocks exhibited the best structural properties and adsorption performance. The biochar derived from conifer trunk showed the highest capacity, reaching 45 mg/g and exceeding commercial biochar performance by 31%, while other forest-derived biochars outperformed the commercial reference by approximately 15%. These results highlight the potential of gasification-derived biochars for CO? capture and biomass waste valorisation, supporting BECCUS strategies for industrial decarbonization.
