“…These biomass residues generated by the wood- and agricultural-based industries in developing countries can replace the domestic demand for traditional energy sources such as firewood and charcoal [ 15 ]. With the present energy-driven technologies in place, it is estimated by the West African Clean Energy and Environment Exhibition (WACEE) [ 16 ] that Ghana has the potential to produce about 110 MW of power from biomass residues only.…”

Energy application potential from the abundant biomass residues is inadequately exploited. Over-dependence on forest trees, its negative environmental impacts, and ever-rising energy costs require alternative production technologies including briquetting. The physico-mechanical and combustion properties of binderless and bindered Alstonia boonei sawdust and Theobroma cacao (cocoa) pod briquettes, carbonized in a steel kiln (at 410±5°C, and a heating rate of 4°C/min from the ambient temperature of 25°C), piston-pressed at 9.0 MPa, were studied. The binders were starch, wax, and clay. Starch-bindered T. cacao pod briquettes recorded the maximum bulk density (640 kg/cm3), while basic density was greatest for sawdust/clay briquette (433 kg/cm3). Sawdust/wax briquette produced much Water Resistance Capacity (76.76%) with safer carbon monoxide (CO) emissions (0.67 ppm). A. boonei sawdust/starch briquettes recorded the greatest calorific value (24.023 MJ/kg), least specific fuel consumption (0.0483 kg/l), and slowest burning rate (0.0005 kg/min). All but T. cacao pod/starch and Sawdust/starch emitted CO below the safe air quality Standard of ≤ 6ppm (24h mean). Binderless sawdust, sawdust/starch and T. cacao pod/starch briquettes recorded 47.86, 20.95 and 11.40 μg/m3 particulate matter (PM2.5) respectively, which are below WHO Air Quality Standard safe for domestic uses. Binderless T. cacao pod produced more harmful CO and PM2.5 than its non-bindered A. boonei sawdust counterpart. Clay-bindered briquettes were the most durable. Briquetting, ‘a waste-to-energy technology’, enhances bio-residue management for domestic and industrial spaces in the global energy mix.

“…Wood residue has a significant potential for utilization due to its renewability and abundantly available. It can be used as domestic fuel and replacing traditional energy source, such as firewood and coal [10,11]. However, this wood residue could not be used directly as fuel due to their bulkiness and high moisture content.…”

HDPE (High Density Polyethylene) is one type of plastics that has been used in many various applications. We frequently used it in our daily life, such as plastic bag, dairy products packaging, etc., which often end up being waste, which is non-biodegradable. This plastic waste has good potential to be used in production of briquettes because it has a high heating value. Teak sawdust is also considered waste and usually not properly utilized. Nevertheless, it has a high heating value and sufficiently low level of volatile matter. Therefore, mixing HDPE plastic waste with biomass charcoal such as teak sawdust to make briquettes as an alternative domestic fuel is an interesting idea. The objective of this research was to make briquettes by mixing HDPE plastic waste and teak sawdust. The effects of two different natural adhesives (i.e. rice flour and corn flour) and the ratio of plastic waste and teak sawdust were investigated. The results of the experiment show that the best ratio of plastic waste and teak sawdust that produce the best quality of briquettes in this study was 50% : 50% and by using rice flour adhesive. The following are the results for this sample, the duration of fire starts to ignite was about 2.3 minutes; the duration of fire boils 125 mL of water was 12.8 minutes; and the duration of the briquettes burn to ashes was about 62 minutes.
