High-performance Process for Anaerobic Digestion of Food Waste for Enhanced Biogas Production using Novel Pretreatment and Bioreactor Design

This anaerobic digestion process converts food waste into renewable energy and nutrient-rich biofertilizer. Using innovative pretreatment and advanced bioreactor design, it accelerates organic matter breakdown, increases methane yield, and reduces retention time. The technology mitigates landfill pressure, lowers greenhouse gas emissions, and provides a sustainable, economically viable solution for waste management, enabling simultaneous energy recovery, nutrient recycling, and promotion of environmental sustainability in industrial and municipal sectors.

The technology is applied for processing municipal, industrial, and household food waste to produce biogas for electricity, heating, or biomethane. It supports co-digestion with agricultural residues to balance carbon-to-nitrogen ratios. Suitable for both small- and large-scale anaerobic digestion facilities, it provides a sustainable waste-to-energy solution while generating nutrient-rich digestate that serves as biofertilizer, closing the loop in organic waste management and promoting circular economy practices.

The process enhances biogas yield and reduces digestion time by improving substrate solubilization and microbial efficiency. It accommodates diverse food waste streams and supports co-digestion with high-carbon residues. Environmental benefits include reduced methane emissions and nutrient recycling, while economic advantages arise from renewable energy generation and biofertilizer production. Overall, it provides a high-performance, flexible, and commercially viable solution for industries, municipalities, and commercial waste management systems seeking sustainable organic waste valorization.
