“The SMARTFERM system is a win – win for the community: allowing us to extract the energy as well as compost from the food scraps generated by our hospitality industry. The implementation of this program will further strengthen the Monterey Peninsula’s reputation as a sustainable destination.”
William Merry, Monterey Regional Waste Management District
“We’re excited about expanding our zero waste program with the opening of this state-of-the-art facility next year. We’ve had a very successful new commercial collection system roll out and will be using the latest proven organics processing technology, allowing us to meet San José’s Green Vision goal of diverting waste from our landfill and converting waste to energy.”
Kerrie Romanow, San Jose Environmental Services Department
“SMARTFERM will give us the ability to reduce the organics going to the landfill by converting that same waste into CNG fuel that will power our collection routes…a true closed loop system. Good for us, the cities we serve, and California as well.”
Doug Button, South San Francisco Scavengers, Co. LLC.
