ENERGY RECOVERY FROM BONE WASTE GASIFICATION
Abstract
This study investigates the energy recovery potential of animal bone waste through pyrolysis and subsequent gasification of the resulting biochar using air and steam as gasifying agents. Experimental results show that steam gasification yields a hydrogen-rich syngas (H₂ = 45 vol.%) with higher heating value (10.2 MJ/Nm³) compared to air gasification (8.9 MJ/Nm³). When extrapolated to a population of 400000 inhabitants, the process could substitute up to 147000 Nm³ of natural gas annually, generating economic savings exceeding 120000 €. These findings demonstrate an efficient sustainable pathway for waste valorization, resulting in fossil fuel reduction, and environmental impact reduction.
