Abstract
Bagasse is a residue obtained from the processing of sugarcane (Saccharum officinarum). The aim of this study was to investigate the temperature profile, biochar yield and product quality of a locally designed thermochemical process for the conversion of sugarcane bagasse (SCB) and low-density polyethylene waste into biochar. Product quality was evaluated using Fourier transform infrared spectroscopy, scanning electron microscopy and Branueur–Emmett–Teller analyses. Product yield was 16.67 wt% and 45.46 wt% at 349°C and 250°C peak temperatures for SCB and hybrid biochar, respectively. Both SCB biochar and hybrid had a heterogeneous surface morphology and was mesoporous. The specific surface area of the SCB and hybrid biochar was 533.6 m2/g and 510.5 m2/g, respectively. The process has a three-pronged advantage of product development, waste management and resource conservation.
