“…19 that as the percentage biomass increased, there was a general increase in percentage content of volatile matter of the bio-coal briquettes. This is in agreement with the results of Estialty et al [49] where coconut biomass was blended with coal at different mesh sizes and found that the volatile matter of the resulting briquettes increased as the percentage biomass in the blend was increased. The increase volatile matter can be attributed to the high volatile matter of the biomass material.…”

“…This might be due to interactions of Volatile matter, moisture content, ash content and fixed carbon and other experimental variations as mentioned above. Estialty et al [49] produced bio-coal using "lowgrade" coal and was able to show that as the composition of the biomass (corn cobs) increased, the calorific values of the briquettes reduced too. In other words, addition of coal to a biomass material in a briquetting process causes improvement in the calorific value of the briquette.…”

This study evaluated the properties of bio-coal briquettes made by blending coal with beniseed (sesame seed) stalks in order to determine the optimum composition. The briquettes were produced using a hydraulic compression machine at 5, 10 and 15 bar applied to coal:biomass compositions of 100:0, 80:20, 60:40, 40:60, 20:80 and 0:100% by weight of mixture and particle sizes of 212, 300 and 600 µm. The physical, ultimate and proximate properties of the briquettes were then measured and analyzed. The results indicated that the optimum composition for producing the briquettes lies between 60:40% and 40:60%. These ranges of composition of briquettes had the lowest ignition time of 57.6s, highest percentage volatile matter of 42.7% and low percentage sulphur content of 0.38%. Furthermore, the 40:60% briquettes had the highest mean calorific value of 26.67 MJ/kg. These indicate good potentials for briquettes using coal and beniseed stalks as an alternative energy source while contributing to a friendly environment and wealth generation.

“…The use of bio-coal briquettes as cooking fuels, especially in improved cookstoves, could provide a solution to the aforementioned health and deforestation problems [4]and help cut down on the consumption of fossil fuel [5].Research has shown that blending coal with biomass to produce briquettes helps to ameliorate the emission problems thus result in anenvironmentally friendly briquette with better combustion and physical characteristics [6].…”

“…The burning of tree plants as a substitute to fossil fuel and electricity for household and industrial uses has led to an extreme reduction in the land mass of Nigeria's forest [1] The direct burning of loose biomass to generate power in place of fossil fuel and electricity results in widespread air pollution and low thermal efficiency. To address these issues the use of briquettes as fuel was developed, it's a technology that has been adopted in several countries, especially in developing nations [2].…”

The rapid increase in the world’s population and urbanization is a threat to non-renewable energy source; crude oil. This necessitates the use of biomass and agricultural waste as an alternative source of energy. This study is aimed at production and characterization of briquettes from Cashew Leaves (CL), Banana Leaves (BL) and CL- BL admixture using Cassava starch as binder. The volatile matter, fixed carbon, calorific value and other physico-chemical parameters of the briquettes were examined under the same experimental condition. The volatile matter, fixed carbon and calorific value of 68.29±0.06 %, 16.51±0.07 % and 23.52±0.02 MJ/Kg respectively were recorded in sample E (at 100% BL) followed by sample D (25% CL+ 75% BL admixture) with 68.34±0.03 %, 16.01±0.03 % and 22.91±0.01 MJ/Kg respectively at p < 0.05.While sample A (100% CL) recorded an average volatile matter, fixed carbon and calorific value of 69.40±0.01%, 12.36±0.02 % and 21.06±0.03 MJ/Kg respectively. The finding of this study shows that the incorporation as well as increase in the percentage of BL in CL-BL admixture progressively improved its quality as biofuel.
