Just in time for , ReGen Monterey, Keith Day Company (KDC), Engineered Compost Systems, Graniterock and Tetra Tech celebrated the groundbreaking of one of the one of the most significant upgrades in our composting operations’ history.
Our new Covered Aerated Static Pile (CASP) Composting Facility will transform ReGen and KDC’s existing windrow composting process into a more advanced system that accelerates composting, reduces odors and emissions, and modernizes the facility with innovative new technologies.
This $8.7 million project — partially funded by a $3 million CalRecycle grant — represents a major investment in cleaner, more efficient organic waste processing and the future of sustainable materials management in Monterey County.
ReGen Monterey is celebrating its 75th anniversary year as an industry leader that continues to invest innovative technology and practices that divert materials from landfills, protect our local environment, fight climate change and strengthen the circular economy.
Since California’s landmark SB 1383 was signed into law in 2016, ReGen Monterey and KDC have been ready to help meet the moment — welcoming curbside food scraps commingled with yard trimmings and transforming them into nutrient-rich compost, 100% of which supports local farms.
ReGen’s mission is “to do more to waste less,” and this project marks a major milestone in putting that mission into action by modernizing our operations, recovering more from what we throw away, and turning local organic waste into a resource that benefits Monterey County.
Follow along on LinkedIn and Instagram as we document this transformation, and thank you to our project partners, CalRecycle, and ReGen’s Board of Directors and leadership for helping turn this vision into reality.
