Abstract
Abstract The effective management of agro-industrial waste plays a pivotal role in mitigating various forms of pollution. Sugarcane bagasse (SB), a substantial biomass waste generated in the sugar industry after cane juice extraction, necessitates sustainable handling. Although some sugar mills utilize wet sugarcane bagasse for fueling the milling process, a significant portion remains stockpiled and is often incinerated on-site, resulting in a highly flammable biomass that poses significant risks to the industry and its surroundings. Recognizing the importance of addressing this issue, researchers have identified the conversion of agricultural waste into biochar as an efficient means of harnessing energy following biomass devolatilization. There is scientific interest in the transformation of biomass into value-added products, including biochar, biogas, and biofuel. This comprehensive literature review delves into various pyrolysis processes applicable for converting sugarcane bagasse into char materials, showcasing its potential for diverse applications in line with current scientific interests.
