Biodigesters for Sustainable Food Waste Management

International Journal of Environmental Research and Public Health, Journal Year: 2025, Volume and Issue: 22(3), P. 382 - 382

Published: March 6, 2025

The global challenge of food waste management poses severe environmental and public health risks. Traditional disposal methods, such as landfilling incineration, exacerbate these issues. Decomposing in landfills emits methane, a greenhouse gas 25 times more potent than CO2, while landfill leachate contaminates soil groundwater with hazardous pathogens toxins. Additionally, improper fosters microbial proliferation, posing Incineration, though commonly used, is inefficient due to the high moisture content waste, leading incomplete combustion further air pollution. Therefore, this review examines biodigesters sustainable alternative traditional disposal, assessing their effectiveness mitigating risks promoting circular economy practices. It evaluates different biodigester designs, operational scalability, economic feasibility across diverse contexts. Through an analysis case studies, highlights biodigesters’ potential address localized challenges by converting organic into biogas—a renewable energy source—and nutrient-rich digestate, valuable natural fertilizer. process reduces emissions, improves health, minimizes associated contamination. Various including fixed-dome, floating-drum, tubular systems, are compared for efficiency adaptability. identifies key barriers adoption, feedstock variability, maintenance costs, policy constraints, also discussing strategies enhance accessibility. This novel its comprehensive approach, bridging technological, environmental, perspectives on management. Unlike prior studies that focused isolated aspects—such specific analyses, or laboratory-scale evaluations—this synthesizes findings real-world implementations, offering holistic understanding impact. By addressing knowledge gaps terms risks, benefits, challenges, study provides insights policymakers, researchers, industry stakeholders seeking solutions.
