California collection program diverts 12,000 tons of organics in first year

An organics collection program in Nevada County, California, has diverted more than 12,000 tons of organics since its launch in January 2025.

Introduced by Houston-based WM to align with California’s Senate Bill (S.B.) 1383 last year, the program added curbside collection of food scraps and food soiled paper for communities in unincorporated Nevada County and the city of Grass Valley, California. The initiative aims to help the state reduce greenhouse gas emissions and advance its sustainability goals, according to a press release from the county.

“We’re encouraged to see the growing participation from our communities in this program,” Nevada County Director of Public Works David Garcia says. “Diverting 12,000 tons of organic materials from landfills is a significant milestone, especially for a program still in its early stages.”

According to Alex Zalasky, district manager for Nevada County at WM, the data shows a 24 percent increase in organics diversion since the program launched in the first quarter.

“More participation means more materials are given the opportunity to be repurposed into new products,” he says. “By diverting organic waste from landfills, communities can support the production of nutrient-rich compost and help reduce the amount of material sent to landfills. We are grateful for the ongoing support of Nevada County and the city of Grass Valley. Strong collaboration with our local government has been essential in addressing challenges, educating the community and keeping the program moving forward.”

As the program enters its second year, WM says it will continue working with customers and county partners to further increase organics diversion, reduce contamination and help the community meet state climate goals.
