The Potential of Food Waste as a Renewable Energy Source in California

Abstract

Food waste represents a significant challenge in the United States, contributing to economic losses and environmental degradation. Given most food waste ends up in landfills, it exacerbates methane emissions, and thus the climate crisis. To address this issue, this study proposes diverting food waste from landfills to renewable energy efforts in California, where organic waste is twice that of any other state, with the unfortunate distinction of having the largest landfill in the nation. This study’s objectives: Aim 1: To determine the capacity of utilizing syngas and biochar for renewable energy production using food waste from a populated urban environment; Aim 2: To analyze and compare the feasibility of implementing anaerobic digestion facilities in cities with various populations across California; Aim 3: To establish costs and outputs of running an anaerobic digestion facility, including acquiring food waste, daily maintenance, and transmission of generated energy. The approach involves conducting a comprehensive analysis of the economic viability, logistical feasibility, and community acceptance of converting food waste into renewable energy sources, particularly syngas and biochar. Drawing upon multiple peer-reviewed articles, government reports, and international case studies, the study explores various aspects of syngas and biochar production, distribution logistics, and public management strategies. Funding mechanisms, including federal grants and state programs, are identified to support the implementation of these renewable energy projects. A cost-benefit analysis reveals the potential of syngas and biochar production to reduce greenhouse gas emissions and promote sustainable waste management practices. The study underscores the importance of collaborative efforts among stakeholders, innovating financing mechanisms, and supportive policies to maximize and reap the benefits of utilizing food waste as a valuable resource for renewable energy production and environmental stewardship. By implementing these solutions, California can move towards a more sustainable future, mitigating the impacts of food waste while advancing renewable energy goals.
