Increased global demand for fossil fuels has led to wealth creation but also exacerbated the negative impacts of greenhouse gas emissions on climate change and public health. By converting biomass wastes into energy-efficient briquettes, substantial environmental and socio-economic benefits can be achieved.
Rising worldwide demand and consumption of fossil fuels have elevated wealth creation, improved undesirable impacts on climatic change from emission of greenhouse gases, and endangered communal health. In developing nations, biomass wastes, which include but are not limited to agricultural residues, are generated in huge quantities yearly. During the disposal of biomass, incomplete combustion causes people to get exposed to elevated indoor concentrations on health-damaging pollutants including particulate matter and carbon monoxide. Inefficient usage or disposed biomass wastes may cause toxic impacts on higher levels of pollution, the consequent degeneration of public health and ecological contamination. It is possible to convert these wastes into energy-efficient briquettes through densification. In this research work, the combustion characteristics were identified from biomass briquettes which were produced from Onion Peels (OP), Tamarind Shells (TS) and Cassava Starch. OP-TS were mixed sequentially and conversely with different proportions. From the total weight of biomass, 10% of cassava starch was added and briquettes were produced under 200 kN pressure from the compressed hydraulic system within the dwell time of 60 seconds. The proximate characteristics such as the presence of water content, amount of fixed carbon, ash and volatile matter were determined by using the standard procedures of the American Society for Testing and Materials (ASTM). The ultimate parameter, which is inclusive of Carbon (C), Hydrogen (H) and Oxygen (O) were diagnosed in all produced biomass briquettes and calorific values were identified for all the produced biomass briquettes as well. OP-TS have better fuel properties in comparison with pine, cotton stalk (CS), wood sawdust (WS), municipal solid waste (MSW) and cotton straw biomass briquettes (CSB). Therefore, the produced biomass briquettes could bring substantial environmental and socio-economic benefits to rural communities and are potentially worthy fuels derived from agricultural wastes.
