Straus Family Creamery Receives Zero-Waste Certification

What does a small trash bin tucked in the corner of a Straus Family Creamery executive office have to do with climate change? Everything, according to Stephanie Barger, director of market transformation and development for TRUE (Total Resource Use and Efficiency), a zero-waste certification program established by Green Business Certification Inc. in 2017. The devil is always in the details, and when it comes to reducing what goes into landfill, everybody—every single employee—must be part of the change.

“A company may have too many trash cans, and that also means too many trash can liners,” Barger says. “People get very attached to trash cans in their offices, and to throwing things away. This is a simple fix: When you remove a trash can it’s not only a technical change but it is also a company-wide cultural change, moving toward zero waste.”

A person wearing a hat, gloves, and work clothes stands at an outdoor research station at Correia Family Dairy, pouring a reddish liquid into a large funnel-shaped container connected to hoses and pipes. Several plastic sample bottles sit on the ground nearby, and shade cloths overhead provide cover. The setup includes pumps, tubing, and monitoring devices, suggesting a water, soil, or nutrient treatment experiment.

These very hungry microbes devour a powerful pollutant

PETALUMA, Calif. — The cows had to be deterred from messing with the
experiment.

Researchers from a Bay Area technology company had come to the sprawling
dairy farm north of San Francisco to test an emerging solution to planetwarming emissions: microscopic pink organisms that eat methane, a potent
greenhouse gas.

Kenny Correia, 35, of Correia Family Dairy, watched the team from Windfall Bio
working near the lagoons used to store manure from the farm’s several hundred
cows. The researchers erected a futuristic system of vats, pipes, tubes and shiny
metal supports. Then, when everything was assembled, they poured pink liquid
into one of the vats. “They were looking like mad scientists out there,” Correia
recounted.

He acknowledged initially thinking it was a “crazy idea” to integrate an outdoor
laboratory into a working farm. There was the potential for the cows to “be all
over it — licking it, pulling out wires and scratching on it,” he said.
But livestock farms are a significant source of methane emissions, and Windfall
wanted to see how much the microbes could help.
