Profitability Analysis of Developed Briquette Suitable for Energy Generation from Residue of Cattle Feed Sorghum Stalk and Groundnut Husk

The world's energy is dominated by technology that uses fossil fuels to generate electricity, chemicals, and materials. On the other side, the usage of conventional energies has resulted in massive environmental damage and climate change. This study looks into the development of briquettes from sorghum stalks and groundnut husks utilizing cow dung as a binder for fuel production using the low-pressure compaction method, which is an important source of renewable energy. The briquettes were labeled with cow dung binder compositions (5% to 25%), ratios (75% to 95%), and particle sizes ranging from 1 to 3 mm. The raw material was collected, cleaned, sun-dried, carbonized, and processed using a mortar grinder. DOE software, excel, and ANOVA were used to do numerical and graphical analyses of the data. After briquetting, the moisture content was 3.16%, fixed carbon 13.04%, volatile matter 80.20%, and ash 3.6%. The briquette had 51.56% carbon, 6.302% hydrogen, 0.0042% nitrogen, 42.134% oxygen, and 0.00093% sulfur. The calorific value of mixed briquettes varies from 20.08 to 24.36 MJ/kg. The maximum calorific value was achieved with a particle size of 1 mm and a 25% cow dung binder content, as a minimal particle size was preferred. According to the analysis, the created briquettes were smokeless, low in Ash content, and had a high Calorific value for burning above 17 MJ/kg for industrial driving and above 13 MJ/kg for residential usage. The development of briquetting technology leads to increased job prospects, decreased greenhouse gas emissions, and the establishment of entrepreneurs.
