| Resource Title | Valorization of Queen Pineapple Waste through Oxidative Torrefaction for Biochar Production and its Application as Solid Biofuel |
| Date Issued | 28 July 2024 |
| Abstract | Waste valorization is among the potential strategies to address waste management issues and renewable energy needs. In this work, valorization via torrefaction is employed to upgrade Queen pineapple waste (QPW) to biochar with enhanced heating value. Optimization and modeling of torrefaction were performed to investigate the influence of process parameters (i.e., moisture content, temperature, and reaction time) on the solid yield, heating value, and energy yield. The models confirm that torrefaction severity influenced biochar properties. Moreover, the environmental impact of the torrefaction process was investigated through a cradle-to-gate life cycle assessment (LCA) employing the ReCiPe 2016 Midpoint (Hierarchy) methodology. The major environmental indicators including global warming potential (GWP) suggest that the utilization of bioenergy during torrefaction has less impact on the environment. Lastly, the technical and economic assessment (TEA) of QPW-derived biochar as a solid fuel for electricity generation and heat application for cooking was performed using a fabricated gasifier stove with a boiler. Furthermore, the economic indicators of biochar enterprise, starting from production to application, suggest that it is economically viable. The key findings of these experimental and computational investigations suggest that QPW can be an alternative biofuel source. The process modeling, LCA, and TEA results reveal that torrefaction can be used to upgrade QPW into biochar with minimal environmental impact and valuable contributions to the circular economy. |
