From Waste to Sustainable Energy: Harnessing Organic By-Products in Developing Eco-Briquettes

This study explored the potential of organic by-products, including agricultural residues and industrial waste, to produce eco-friendly briquettes as a sustainable alternative to conventional fuels like charcoal and coal. The research evaluated the efficiency, environmental impact, and practical applications of these eco-briquettes. Biomass, as highlighted by Yunusa et al. (2023) [7], played a crucial role in reducing deforestation and greenhouse gas emissions, contributing to the transition to renewable energy sources. Employing a quantitative, quasi-experimental design, the study examined various factors such as material composition, compaction pressure, and drying conditions on briquette performance, including burning time, ignition time, and quality. Data collection involved pre- and post-test assessments, controlled tasks like burning, and efficiency tests comparing briquettes to traditional fuels. Participants used biodegradable materials such as sawdust, coconut fiber, ground coffee, and dry leaves, chosen for their energy potential, cost-effectiveness, and availability. Key findings revealed that mixed-material briquettes had superior ignition times and burning efficiency, with a lifespan of 3661 seconds. These briquettes also showed resistance to water dissolution, indicating stable storage, and partial biodegradability, suggesting long-term environmental sustainability. The study concluded that eco-briquettes offered a promising alternative to traditional fuels, promoting renewable energy adoption and supporting circular economy principles. Recommendations included optimizing briquette production with additional biodegradable materials, conducting long-term biodegradability tests, and enhancing community awareness to drive adoption.
