Abstract

Global waste generation has been a challenging issue affecting humans and the environment. The conversion of vast amount of agricultural and polymeric waste to briquette may bridge the energy deficit and environmental pollution issues in developing economies. On the other hand, the utilization of biomass waste or residue as energy source could help alleviate dependence on imported energy and its use continues to be a topical issue in both developing and developed countries. Over the years, biomass has been an important source of generating energy due to its relative availability and the ability to meet both heat and electricity demand by contributing towards international commitments so as to minimize environmental degradation and maximize environmental, social and economic sustainability. The benefits of compacted biomass compared to all other types of biofuel include its low transportation and storage costs, uniform product quality such as constant humidity content and high mass fluency. Moreover, fuel wood and biomass residues have low combustion efficiency, also posing environmental and health hazards. This research studies the performance of briquettes produced from maize cob, sugarcane bagasse and polythene waste composites. The briquettes were agglomerated using cassava starch binder (CSB) and plantain peel binder (PPB) at binder concentrations 4%, 12% and 20%. Each briquette was characterized in terms of proximate analysis, calorific value ultimate analysis and micro-structure by Scanning Electron Microscopy. The briquettes contained moisture content 5.39-12.10%, volatile matter 10.15-23.08%, ash content 10.29-24.63%, fixed carbon content 55.84-77.10%, calorific value 9.04-28.14 MJ/kg, carbon content 77%-8405%, nitrogen content 0.875-1.05% and sulphur content 0.4-0.7%. The result from this study reveals that briquette with CSB at 4% binder concentration had the best properties required for biomass fuel briquette than that of PPB and suggests its use for the production of environmentally friendly solid fuel.
