Commercial Compost Service

Mill Valley Refuse Service provides commercial compost service in Almonte, Alto, Belvedere, Corte Madera, Homestead, Mill Valley, Strawberry, Tiburon and several unincorporated areas of Marin County.

Visit our Commercial Service Guidelines to learn more about our collection service.

It’s the law: Businesses that generate four or more cubic yards of solid waste must subscribe to an organics recycling service (i.e. compost service). Learn more.

What Goes Where?

cNot sure how to properly dispose of something? Search our What Goes Where tool to find out if a material can be reused, recycled, composted, or disposed of in your trash.

Tip: This tool works best if you search for categories instead of a brand name or very particular product. For instance, rather than “Coffee-mate container” search instead for “plastic beverage bottle.” Instead of “cottage cheese container” search instead for “plastic tub.”

What Can and Can’t Go In The Compost Cart

The green cart is for compost material only.

It is important that we do not contaminate our compost with hazardous or non-biodegradable items. Please be careful to insure that only approved organics go in the Compost Cart.

Below are guidelines about what can and cannot go in your Compost Cart, but we suggest using the What Goes Where tool above to look up specific items.

Sorry, No Compostable, Biodegradable, or Bio-Plastic Items in the Green Compost Cart

Just because a product label claims it is compostable or bio-degradable, if it is not recognized by the US Department of Agriculture as feedstock for compost used in organic farming, WMearthcare/Redwood Landfill (the company that composts the materials collected by Mill Valley Refuse Service and other Marin and Sonoma County haulers) cannot accept them.

Bio-Plastic Food Ware

Some bio-plastics may contain harmful chemicals such as PFOs and PFAs.
When non-compostable bio-plastics enter compost processing facilities, they contaminate the waste stream.
Bio-plastics do not always break down during the composting process.
Bio-plastics look a lot like their plastic counterparts during the composting process.
When bio-plastics end up in oceans and bays, they behave similar to regular plastics in the way they decompose, potentially harming marine life.

Compostable Bags

Even though BPI-certified compostable bags meet a laboratory test for compostability, this standard is not recognized by the US Department of Agriculture National Organic Program, which certifies compost for organic farming application. What’s more, compostable, biodegradable and petroleum plastic bags are indistinguishable in the 500 tons of material Redwood Landfill processes a day.

Instead, try transferring contents from your food-scraps pail into a paper bag to carry out to your Compost Cart. This offers the benefit of a carbon source, odor reduction and moisture-absorbing container!

Food Service Providers: County of Marin Reusable Food Ordinance in Development

The County of Marin is developing a Reusable Food Ordinance that would define alternative materials that would be acceptable for composting, include language about consistent implementation of the policy, and lay out a coordination plan with the local food service industry.

Learn more about the project and view the public draft on the County of Marin’s website.

Compost Cart Odor

Try layering dry yard waste and wet food waste to contain odors. When you don’t have yard waste, putting a layer of newspaper or shredded documents at the bottom of the cart, and bagging food scraps in a paper shopping bag is an option. Keeping the lid closed at all times holds odors in, even if the interior smells between pickups.

It’s the Law

California commercial businesses that generate four or more cubic yards of solid waste must subscribe to an organics recycling service (i.e. compost service). Don’t worry, we’ve got you covered!

The Benefits of Composting

Food scraps and food-soiled paper make up about 23% of Marin’s residential waste stream, and as much as 40% of all food harvested is wasted in one way or another (see the short videos below to learn more). When you compost in your green Compost Cart, your organic waste will be diverted from the landfill to create a rich and nutritious soil amendment that can be put back in the earth, closing the “recycling loop.”

How Compost Works

Collect your food scraps and food-soiled paper items in kitchen pails, bowls, or bins and then transfer the food scraps to your Compost Cart along with your yard waste.
We empty your Compost Cart once a week and transport your organics to The Redwood Landfill and Recycling Center.
Food scraps, food-soiled paper and yard waste are processed into Homegrown Compost, a premium, affordable compost which you can purchase directly from The Redwood Landfill’s WM EarthCare™ Center in Novato.
Gardeners and farmers apply compost to soil to improve moisture retention and nutrient value of soil. Plants grow… and the cycle continues!
