Retrofitting a CST Biogas Plant for the Production of Biogas from Rice Cooking Waste Water

The generation of biogas from rice cooking wastewater offers a sustainable and eco-friendly method for managing waste and producing renewable energy. This study investigates the viability of using rice cooking wastewater, a large food preparation by-product, as a substrate for anaerobic digestion-based biogas production. The study emphasizes how this waste stream has the potential to produce methane-rich biogas while simultaneously reducing its harmful effects on water systems. The main focus of the study is to identify the current issues with the biogas facilities at the College of Science and Technology (CST) that made the plant inoperable and to develop a retrofitting design for the existing plant to make it technically and financially feasible. The study also provides a quantitative analysis of the methane content of rice-cooking wastewater, and the findings show the possibility of using rice-cooking wastewater to produce biogas as a dual-benefit solution to energy needs and waste treatment issues.
