Chennai, Semmancheri – Sathyabama University has taken a sustainable step towards managing its food waste by implementing a biogas solution on its campus. The university’s hostel, which produces a staggering one tonne of food waste per day, has partnered with Green Connect to install a one-tonne biogas plant. This eco-friendly initiative not only aids in waste management but also contributes to cost-saving measures for the university.
The biogas plant has proven to be highly efficient, producing 80 cubic meters of biogas per day, which is equivalent to 40 kg of LPG. By utilizing the biogas in their hostel kitchen, Sathyabama University has significantly reduced its reliance on LPG, resulting in substantial cost savings. The implementation of this sustainable solution aligns with the university’s commitment to promoting environmentally friendly practices.
Moreover, the presence of a biogas plant on the university campus serves as an added advantage in fulfilling the criteria for NAAC accreditation. In addition to its practical benefits, the biogas plant also serves as a valuable resource for research purposes within the university. Researchers and students can utilize the plant to study and explore various aspects of biogas production, waste management, and renewable energy.
To initiate the biogas production process, a combination of 10 tonnes of cow dung and 1000 liters of water was added. To expedite the kickstarting process, 50 kg of sodium bicarbonate was added daily until the plant reached optimal functioning. Initially, the first gas formed mostly consisted of carbon dioxide (CO2), rendering it non-combustible. Hence, this gas is usually released as part of the process.
To enhance the monitoring and management of the biogas plant, Sathyabama University has integrated a smart biogas flow meter as an accessory. This innovative technology allows users to monitor gas pressure and gas generation remotely through a smartphone application connected to the internet. The smart flow meter provides real-time data, enabling efficient and timely decision-making regarding gas utilization and maintenance.
Sathyabama University’s implementation of the biogas solution showcases its commitment to sustainable practices, waste management, and research advancements. By harnessing the potential of biogas, the university not only reduces its environmental footprint but also contributes to cost savings and academic development.
