‘Complicated choice’ looms in Sonoma County over next compost operator

Kevin McCallum, THE PRESS DEMOCRAT

Every week, hundreds of thousands of Sonoma County residents dutifully gather grass clippings from their yards and food scraps from their kitchens, toss them into green bins and then cart them to the curb alongside their garbage and recycling.

Tons of this so-called “green waste” is then hauled, at a cost of $5 million per year, to other counties, where it is chopped up, often mixed with chicken guts, encouraged to rapidly decompose, and then sold as compost.

The process takes place entirely outside Sonoma County — mostly in Mendocino, Napa and Marin counties — ever since Sonoma Compost, the county’s longtime compost operation atop the Central Landfill, was shut down nearly three years ago for wastewater violations.

Now local officials face a complex but crucial decision about the future of composting in Sonoma County, one that will have major implications for the life of the county landfill, the rate of emission of greenhouse gases and the size of people’s garbage bills.

That decision is whether to encourage the construction of a new, modern composting facility here, with costs of $50 million or more, or whether to continue hauling the material to existing facilities elsewhere indefinitely.

Commercial compost operation proposed in Santa Rosa

Kevin McCallum, THE PRESS DEMOCRAT

Sonoma County is getting closer to once again having a large-scale commercial composting operation.

Staff at the Sonoma County Waste Management Agency, which is responsible for recycling operations in the county, is recommending partnering with Renewable Sonoma in a new composting operation in Santa Rosa.

Renewable Sonoma is owned by Sonoma Compost, the organization that operated a compost yard atop the Sonoma County landfill from 1993 to 2015, when it was shut down over water quality concerns.

Will Bakx, co-owner and CEO of Renewable Sonoma, said the new venture seeks to create a renewable energy and composting facility next to the Laguna Treatment Plant on Llano Road southwest of Santa Rosa.

Santa Rosa open to new composting operation at Laguna wastewater site

Kevin McCallum, THE PRESS DEMOCRAT
Santa Rosa is open to a large-scale composting operation on city-owned property near the Laguna Road wastewater treatment plant, an option that could provide curbside garbage customers some monthly savings.
The Sonoma County Waste Management Agency has been looking for a new site for an organic composting facility since a longtime operation atop the Central Landfill west of Cotati was shut down by regulators in 2015 over water pollution concerns.
Since then curbside customers have been paying millions of dollars to have their organic garbage hauled out of the county, an expensive, wasteful process that local officials want to end.
The county waste agency invited composting companies to submit proposals for a new facility in late May. As part of that process Santa Rosa made it known it might be willing to allow such an operation on surplus property north of the treatment plant.
The city interviewed potential operators, reviewed their plans, and winnowed the list to four companies it felt would be the best fit, said Emma Walton, water refuse engineer for the city.
The four finalists were San Diego-based BioMRF, the multinational firm Sacyr, StormFisher, which is headquartered in London, and a Petaluma-based venture called Renewable Sonoma, which appears to have partnered with SCS Engineers in Santa Rosa.

Sonoma County officials seek to resurrect regional green waste composting operation

J.D. Morris, THE PRESS DEMOCRAT
The search for a new home for composting Sonoma County’s green waste is moving forward as officials seek to finally end the costly practice of shipping green-bin material off to neighboring counties.Within several years, the county may again have a single main facility — or several smaller ones — to process grass clippings, food scraps and other green waste, which has been sent by truck to other counties for the past year and a half since the former central site shut down amid a lawsuit over water pollution concerns.
It is not yet clear exactly what form a renewed regional compost operation — long a disputed county matter — would take. But the Sonoma County Waste Management Agency is advancing plans to bring in a private operator to handle the green waste from local cities, with a request for development proposals likely going out later this spring.And the waste agency — which is on the cusp of securing a new lifeline from local governments — is looking to learn from its past troubles by shifting as much responsibility as possible onto the shoulders of the new private operator.
“Essentially, we’re just the customer at this point,” said Patrick Carter, the waste agency’s executive director. “We’re committing a flow of green waste to a private company on private land, where they assume all of the liabilities for making sure that it is in compliance and operating correctly, in exchange for us committing our flow for 10-plus years. It’s a different model.”
Sonoma Compost Co. processed green waste at the county’s central landfill west of Cotati from 1993 until October 2015, when its closure was triggered by a Clean Water Act lawsuit.
The county began sending green waste to sites in Ukiah, Napa, Novato and Vacaville for disposal, a practice that now costs more than $4.7 million annually, according to Carter.
