Study of Cost Economic Analysis of Biomass Briquetting

In this study selected biomasses are stalks of Cotton, Pigeon Pea, Sunflower, Ground Nut Shell, and Cumbu Napier Grass. Biomass briquetting operation consists of three major unit operations such as drying, grinding and briquetting. Moisture content of biomass is reduced up to 8–12 percent by solar tunnel dryers. Cost of operation for size reduction is Rs 432 per tones. Briquettes production has total cost of operation Rs 940 per tones. Net cost of production of briquettes from above biomass is in the range of Rs 2622 to 3322/tone. Achieved profit in production of briquettes are Rs 378/tones, Rs 878/tones, Rs 178/tones, Rs 678/tones, Rs 678/tones respectively, among which Pigeon Pea Stalk briquettes has the highest profit. Simple payback period achieved highest for Ground Nut Shell briquettes 9.12 years and lowest for Pigeon Pea Stalk briquettes 1.8 years.
