Westminster, CA Trash & Recycling: Mandatory Organics Recycling (2026)

As a city of more than 70,000 residents, Westminster is not rural-exempt from SB 1383, so organics collection is required. Residential organics service is delivered by the Midway City Sanitary District (MCSD) through the green cart, available in 65-gallon and 95-gallon sizes and collected weekly on the regular collection day. The green organics cart accepts yard waste (grass clippings, plants, leaves, weeds, twigs and small branches) and food waste (leftovers, sauces, eggshells, coffee grounds and filters, peels, pits and seeds, meats, fish, poultry and bones, pasta, bread and rice), plus dog waste and paper towels used to soak up fats, oils and grease. All single-family residences serviced by MCSD are required to participate, though certain multifamily properties may qualify for exemptions. Collected organics are taken to CR&R's Anaerobic Digestion facility in Perris, CA, where green waste and food scraps are converted into renewable natural gas. For commercial and large multifamily generators, the city runs MORe (Mandatory Commercial Organics Recycling) under AB 1826: covered businesses must source-separate organic waste into a designated container collected by the MCSD franchisee. SB 1383 and AB 1826 are California mandates; Westminster (through MCSD and Public Works) implements them locally. Bagged pet litter and bathroom waste go in the black cart, not the green organics cart.
