There is a lot of promise for the creation of briquettes made of wood dust, rice husks, and cow menure as alternative fuels. The water content (%) and ash content (%) was measured in this study. Carbon ratio (%), value calorific (cal/g), briquettes’ percentage of volatile content and their compressive strength (g/cm2). A financial feasibility analysis of briquettes was also conducted as part of this study. Sample 1 briquettes had a water content of 16%, whereas sample 2 briquettes had a water content of 12%. Because the results of this water content test range between 5% and 20%, they are still considered acceptable. According to the test results, sample 1 had an ash level of 33% and sample 2 had an ash value of 29%. There were 65% and 60% of flying chemicals in sample 1 and sample 2, respectively. The quality of the briquettes increases with decreasing volatile matter content. From the test results, sample 1 of the briquettes has a carbon level of 2%, whereas sample 2 has an 11% carbon content. Because carbon concentration affects the calorific value, it is a measure of fuel quality. Sample 1’s briquette density is 0.539 g/cm3, whereas sample 2’s briquette density is 0.337 g/cm3. Briquettes for sample 1 have a compressive strength of 13.26 g/cm2, whereas sample 2 has a compressive strength of 15.3 g/cm2. Overall, the briquettes’ financial feasibility study is really promising, with a favorable net present value (NPV) of 144.074.566, a high internal rate of return (IRR) of 72.154%, a respectable net B/C of 4.37, and a comparatively short payback period (PBP) of 3.22 years. This indicates the value of continuing this project. It is believed that by using these briquettes, the amount of deforestation would decline and the dependence on firewood will decrease. We may protect biodiversity and ecosystems by protecting forests.
