Recycling Requirements: Santa Rosa vs Sonoma

Is recycling mandatory in unincorporated Sonoma County?

For businesses and multifamily properties, yes — California's AB 341 requires recycling for those generating 4+ cubic yards/week and multifamily complexes of 5+ units. Residents are expected to keep recyclables out of the trash using Recology's blue cart.

Is the recycling rule a county ordinance or state law?

It is primarily California state law (AB 341, reinforced by SB 1383) implemented locally by Zero Waste Sonoma and the franchised hauler, not a stand-alone numbered Sonoma County Code section.

Do I have to recycle in Sonoma or can I throw recyclables in the trash?

Recycling is mandatory. SMC Ch. 7.10 implements California SB 1383, AB 341, and AB 1826 — every residential and commercial generator must source-separate recyclables (blue cart) and organics (green cart) from trash. SB 1383 (14 CCR §18997.2) authorizes the City to fine non-compliant generators up to $500 per day for major or repeat violations.

Can I put compostable plates and bio-plastic cups in the green cart?

No — even though products are labeled 'compostable,' the City's Sort It Sonoma! program states the regional composter does not accept compostable bio-plastics. Put them in the gray trash cart. Only food scraps, food-soiled paper, and yard trimmings belong in the green organics cart.
