In a step towards sustainability, the Salem Employee Provident Fund (EPF) office has partnered with Green Connect to manage its canteen waste effectively. The collaboration began in June 2024, when the Salem EPF office sought a solution for the approximately 6 kilograms of food waste generated daily.
Green Connect, a company specializing in waste management solutions, proposed the installation of a biogas plant tailored to the office’s needs. This biogas plant is designed to process 6 kilograms of food waste daily, producing around 0.75 cubic meters of biogas per day.
The amount of biogas generated is equivalent to 0.375 kilograms of Liquefied Petroleum Gas (LPG). This conversion allows the Salem EPF office to replace approximately 11.25 kilograms of LPG with biogas every month, reducing its reliance on conventional fuel sources.
The use of biogas not only provides a sustainable source of cooking gas for the canteen but also contributes to a self-sufficient waste management system. Additionally, the biogas plant generates slurry as a byproduct whenever food waste is fed into it. This nutrient-rich slurry is an excellent organic manure and is being utilized to nourish the gardens within the EPF office premises.
The initiative has been well-received, showcasing a model for sustainable practices in government offices. By converting food waste into a valuable resource, the Salem EPF office is setting an example of how waste can be effectively managed while supporting environmental conservation efforts. The project highlights the dual benefits of generating renewable energy and producing organic fertilizer, aligning with broader goals of sustainability and responsible waste management.
