| Abstract |
The world population's rapid growth has led to a surge in solid waste production, posing complex waste management challenges. This study explores the use of food waste for biogas production through anaerobic digestion, offering a sustainable solution. Anaerobic bacterial consortia were utilized to produce biogas from vegetable waste, banana peels, and cow dung. Proximate analysis revealed that a solid concentration exceeding 15% is crucial for effective anaerobic digestion. pH levels shifted from 4.2 to 6.9 post-digestion, indicating successful fermentation by methanogenic bacteria. Co-digestion of cattle dung with food waste yielded the highest cumulative biogas output of 1732 ml, surpassing mono-digestion at 1035 ml. Validation through a flame test confirmed biogas's viability as a renewable energy source. Bacterial isolation highlighted their role in enhancing biogas output and process stability. Life cycle assessment (LCA) emphasized the environmental benefits of anaerobic digestion-based biogas production, underscoring its potential for sustainable waste management and bioenergy generation. |
