In California, legislation such as SB1383 has set ambitious yet achievable goals to divert 75% of organic waste from landfills by 2025. To tackle this challenge, ReGen Monterey has embraced innovative approaches, including the Monterey Biochar Project #1 - a partnership project with Sitos Group.
Tackling California's Organic Waste
California generates over 40 million tons of green waste annually, with more than half of it ending up in landfills. Repurposing this organic waste into high-quality biochar and compost presents a promising solution to this challenge. Regional waste facilities like ReGen Monterey are leading the way, showcasing the effectiveness and efficiency of sustainable waste management practices and laying the foundation for a more circular economy.
Integrating Biochar into Municipal Composting
Sitos Group's Monterey Project #1 is a collaborative effort that seamlessly integrates biochar, produced from ReGen Monterey's local wood waste collection center, into the municipal composting operations of Keith Day Ag Services. This collaboration mirrors the principles outlined in a recent study titled "Seeking the synergistic potential of biochar integration in municipal composting plants for techno-economic and environmental leverage”.
Compost GHG Reduction: The Power of Biochar
Studies have confirmed that biochar-amended composting can significantly reduce greenhouse gas emissions. Biochar enhances microbial activity and alters decomposition pathways, leading to more efficient organic matter breakdown and reduced methane production. By incorporating biochar into Keith Day's municipal composting operations, the project further enhances an already effective green waste management system.

Sequestering CO2 and Regenerating Soils
Beyond waste management and greenhouse gas reduction, Sitos Group is dedicated to revitalizing California's soils. By injecting biochar-amended compost into the earth, the project enriches soil health and fertility, promoting improved nutrient retention, water retention, and microbial activity. This commitment to building a regenerative future through agriculture is at the heart of the Monterey Project #1.
Collaboration, Innovation, & Commitment
Through collaborative efforts, innovation, and a shared commitment to sustainability, Sitos Group, ReGen Monterey, and Keith Day are leading the way in revolutionizing waste management practices. While biochar creation alone is not the sole solution, integrating it into municipal composting services, such as those offered by Keith Day AG Solutions, forms a robust approach that contributes to durable carbon sequestration, soil reclamation, and stimulates economic growth and social responsibility.
