This study investigates the impact of various binder materials on the mechanical and thermal properties of biofuel briquettes. Given the increasing demand for sustainable energy solutions, optimizing briquette quality is essential for enhancing their usability as a renewable fuel source. Different binders, including starch, molasses, and lignin, were tested in combination with diverse biomass feedstocks. Mechanical properties such as compressive strength, durability, and density were measured, while thermal properties including calorific value, ignition temperature, and combustion efficiency were also assessed. The results indicate that binder type significantly influences the mechanical integrity and thermal performance of briquettes. For instance, starch-based briquettes exhibited superior compressive strength and higher calorific values compared to those with lignin. Additionally, the study found that optimal binder proportions can improve burning rates and reduce ash content, thereby enhancing overall combustion efficiency. This research highlights the critical role of binder materials in biofuel briquette production and provides insights for manufacturers seeking to optimize briquette quality for various applications. The findings contribute to the development of more efficient and environmentally friendly biofuel solutions, supporting the transition toward renewable energy sources

Binder material, Biofuel briquettes, Compressive strength, Combustion efficiency

The significant impact of binder materials on the mechanical and thermal properties of biofuel briquettes, emphasizing their crucial role in optimizing performance and usability. Natural binders, such as starch and lignin, enhance the compressive strength and durability of briquettes, making them more resilient during handling and storage. This is particularly important for commercial viability, as stronger briquettes minimize breakage and loss during transport. The density of briquettes, which correlates with energy content, is also improved with natural binders, ensuring efficient use of biomass resources. The choice of binder directly influences ignition temperature and calorific value. Briquettes with natural binders typically exhibit lower ignition temperatures, facilitating easier combustion and quicker energy release. Moreover, higher calorific values observed in briquettes made with lignin indicate their superior potential as a fuel source. In contrast, synthetic binders tend to increase ignition temperatures and lower calorific values, which can hinder combustion efficiency and lead to more unburned residues. The use of natural binders aligns with sustainability goals, as they are derived from renewable sources and contribute to lower ash content, promoting cleaner combustion. This is beneficial for both environmental impact and regulatory compliance. Economically, the cost-effectiveness of using natural binders can enhance the market appeal of biofuel briquettes, especially in an increasingly eco-conscious marketplace. The importance of selecting appropriate binder materials to enhance the mechanical and thermal properties of biofuel briquettes. Natural binders offer numerous advantages over synthetic options, making them preferable for producing high-quality, efficient, and environmentally friendly biofuels. Future studies should explore innovative binder formulations and their long-term effects on briquette performance to further advance this field and support the transition to sustainable energy sources
