Abstract- The growing demand for sustainable and renewable energy has increased the importance of biomass- based fuels.
Biomass pellets are an efficient form of biofuel made from agricultural and organic residues, providing an eco-friendly alternative to conventional fossil fuels. However, the calorific value (CV) and durability of raw biomass pellets are often limited due to their high moisture content and weak binding strength. This study focuses on a techno-economic analysis of using Jatropha oil as a binder and energy booster in biomass pellets. Jatropha oil, being rich in carbon and having good flammable properties, enhances the calorific value and mechanical strength of the pellets. Experimental trials were conducted by blending controlled quantities of Jatropha oil with biomass feedstock, followed by densification under optimal pressure and temperature. The results indicated a significant improvement in pellet density, durability, and calorific value compared to untreated biomass pellets.The study concludes that Jatropha oil is a promising additive for improving both the energy and economic efficiency of biomass pellets, making them more suitable for clean and sustainable energy generation. Keywords: Biomass Pellets, Jatropha Oil, Calorific Value,Biofuel, Techno-Economic Study, Renewable Energy.
I. INTRODUCTION In recent years, the demand for renewable and sustainable sources of energy has significantly increased due to the depletion of fossil fuels and rising environmental concerns. Biomass has emerged as one of the most promising renewable energy resources because it is abundantly available, carbon-neutral, and capable of being replenished within a relatively short period compared to conventional fossil fuels. The utilization of biomass for energy generation not only helps reduce dependency on non-renewable fuels but also contributes to lowering greenhouse gas emissions. Biomass pellets are a compact, densified form of biofuel produced from agricultural residues, forestry waste, and organic materials. These pellets offer several advantages such as ease of handling, transportation, uniform size, and higher energy density. However, the natural limitations of raw biomass—such as high moisture content, low calorific value, and poor binding strength—restrict its widespread application for efficient energy generation. To overcome these challenges, various methods have been explored to enhance the calorific value (CV) and mechanical properties of biomass pellets. In this study, Jatropha oil has been selected as a binder and energy booster due to its high carbon content, good flammability, and natural adhesive properties. The integration of Jatropha oil into biomass pellets improves the binding strength, reduces moisture absorption, and increases the calorific value, making the pellets more efficient for thermal applications.
II. Literature Review The use of biomass as a renewable source of energy has gained significant attention over the past two decades due to its potential to replace fossil fuels and reduce carbon emissions. Several researchers have explored different methods to improve the calorific value, density, and durability of biomass pellets and briquettes.
