What Can and Can’t Go In The Compost Cart

Mill Valley Refuse 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.

The following items are accepted in the Compost Cart. (If it’s not on the list below, please trash the item.)

Food Scraps

  • Fruits
  • Vegetables
  • Meat
  • Poultry
  • Seafood & shellfish
  • Bones
  • Rice
  • Beans
  • Pasta
  • Breads & Grains
  • Cheese
  • Eggshells
  • Coffee grounds
  • Plate scrapings
  • Leftovers

Food-Soiled Paper

You may also place one (1) tied bundle of cuttings 2ft x 5ft next to the cart.

Instead of the Compost Cart you may put three (3) tied bundles 2ft x 5ft at the curb on your scheduled pick-up day.

  • Waxed paper
  • Paper ice cream cartons
  • Milk cartons
  • Liquids
  • Styrofoam
  • Glass
  • Metals & foil
  • Plastic bags & containers – Even biodegradeable plastics. Unfortunately, biodegradeable plastics break down at different temperatures than organic materials, so they don’t compost well together. Also, these plastics can’t be distinguished from regular plastic during processing.
  • Plastic flower pots
  • Plastic trays
  • Diapers
  • Cat litter
  • Animal waste
  • Rocks & dirt

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!

Why Compost?

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!
