Get ready to D-I-Y your C-O-M-P-O-S-T!
Developed by OES through two USDA grants, the DIY Johnson-Su Bioreactor Guide shares lessons learned from building and equipping community leaders to manage more than 60 bioreactors at community gardens, orchards, schools, and urban agriculture sites across Cincinnati.
The guide includes step-by-step instructions, material lists, maintenance tips, and best practices for creating low-cost, low-maintenance composting systems that help divert food waste from landfills and create nutrient-rich compost. Now that the grants have ended, please lean on this new, comprehensive tool to ensure composting continues to spread throughout Cincinnati!
