Co-Carbonisation of Biomass-Plastic Wastes in an Integrated Thermochemical Process

The aim of this study was to convert different biomass/agricultural wastes and LDPE to hybrid biochar in a thermochemical reactor. The LDPE was added in doping amount (4%) in all processes considered. The conversion was a hybrid one involving the simultaneous carbonisation process. The yield of hybrid biochar was in the range of 27.8 wt% and 71.43 wt%, higher than convention biochar yield. The products were characterised using SEM-EDS, and BET analyses. The specific surface areas of the hybrid biochar were all above 300 m2/g. It was observed that the quantity and quality of were higher for hybrid conversion process than for biomass conversion alone. The study has been able to successfully achieve the twin goal of solid waste management and product development.
