Abstract

The increasing food waste epidemic contributes to environmental degradation through amplified GHG emissions, notably CH4, from MSW landfills. Addressing this challenge is essential for public health and environmental sustainability. This research reviews municipal composting initiatives within the San Francisco Bay Area, evaluating effectiveness, efficiency, and sustainability. Utilizing data from CalRecycle and local municipalities, this study analyzes different composting processes, regulatory compliance with California’s Senate Bill 1383, and factors affecting waste diversion rates. Key discoveries indicate that in-vessel composting shows better efficiency and compost quality compared to windrow methods, particularly suitable for urban counties with space limitations. However, participation rates in municipal composting programs vary significantly, influenced by convenience, policy incentives, and community education. The paper suggests that enhancing local composting infrastructure and targeted community engagement are essential. Recommendations include investing in scalable composting technologies and reinforcement of inter-agency collaboration to maximize organic waste diversion.
