Abstract

Converting the de-oiled cashew nut shell into usable products (e.g. briquettes) will address the problem of waste disposal. The study was conducted to develop an environment-friendly fuel briquette sufficient to resist impact during handling and transport and produce the required heat for domestic cooking and also for industrial application. Piston-type and screw-type briquetting machines and three levels of binding agent were used in the production of de-oiled spent cashew shell-based fuel briquettes. The produced briquettes were subject for physicochemical, mechanical and thermal properties tests. Results showed that the best formulation that is required to produce a good quality de-oiled cashew nut shell fuel briquettes using both piston-type and screw type briquetting machines is 10 % binding agent with briquette density, shatter resistance and compressive strength of 0.87 g/cm3 and 0.83 g/cm3, 99.54 and 99.89 % and 43.97 and 101.82 kPa, respectively. The total electricity consumption is 150.91 kWh per ton of briquettes while LPG consumption is 1.32 kg. It is concluded that the energy values and combustion qualities of the briquettes produced in this study are sufficient enough to produce the required heat for domestic cooking and a potential for industrial application.
