Solar-integrated biogas reactor for efficient kitchen waste conversion to biogas Available to Purchase

This study aimed to improve biogas production by co-digesting kitchen waste and animal manure in a solar-integrated biogas reactor. The panel then heated the substrate mixture to the right temperature for the reactor after turning solar energy into electricity. The experiment was conducted at mesophilic (37°C) and thermophilic (40°C) conditions. After 45 days of co-digestion of animal dung, kitchen trash, cow manure, and grasses, the solar-integrated biogas plant generated 1445 mL of biogas with 60% methane (CH₄), 14% carbon monoxide (CO), and 21% other gases; in comparison, the conventional biogas digester produced 501, 479, and 525 mL, respectively, with 35%–50% methane, 18% carbon monoxide, and 22% other gases. The data show that a solar-integrated biogas plant may react faster, produce more gas, and have a higher methane concentration using kitchen waste and animal manure. An environmental effect analysis and prediction of biogas plant construction has been accomplished. The proposed biogas plant, supported by a solar-integrated reactor strategy, appears economically viable, projecting a 5-year payback period. This research evaluates efficient biogas production techniques, emphasising their importance in advancing engineering sustainability. It promotes the role of renewable energy, energy efficiency, and environmental sustainability in solving global energy problems and reducing climate change.
