Backyard composting

Composting is one of the best opportunities to reduce our trash — about 25 percent of what we throw away is organic materials like food scraps and compostable paper that could be put to better use as compost. Composting involves collecting food scraps and non-recyclable paper to be turned into compost in a bin in your yard. This process creates a nutrient-rich material that can be used in gardens and landscaping projects.

How to compost

Add materials

Many people understand what can be composted in backyard bins but can get confused about what not to compost.

Do compost

  • Yard waste, including grass clippings, plant trimmings and leaves
  • Kitchen waste, including fruit and vegetable scraps, coffee grounds, tea bags and egg shells
  • Small amounts of sawdust, wood chips, wood ash, and small sticks
  • Non-recyclable papers: paper towels, napkins, egg cartons

Don't compost

  • Meat and dairy
  • Fats and oils
  • Pet waste
  • Weeds with seeds
  • Large pieces of wood

As a general rule, add three parts of dry, brown materials to one part of wet, green materials. Brown materials include dried grass, leaves, straw, sawdust and twigs; green materials include coffee grounds, fruit and vegetable scraps, grass clippings, green leaves and plant trimmings.

Home composting systems typically don’t reach high enough temperatures to break down meat, dairy, grease and oil. These materials can also attract critters to your compost bin and cause foul odors.

Feces from pets may carry pathogens that could cause health problems.

Large pieces of wood do not compost quickly and require a lot of energy to decompose, so wood should be chipped or shredded and used minimally.

Maintain your compost pile

Follow these tips to maintain a successful compost pile:

  • Keep your compost pile at the right moisture level. If your compost pile has a bad odor, it lacks air circulation or it may be too wet. Try turning the pile and/or adding dry, brown materials to the pile.
  • If your compost pile is not heating up, it may need more nitrogen or "green" material. Add grass clippings to the pile.
  • Bury kitchen scraps at least 8 inches deep in the compost pile to discourage critters.
  • You can keep adding to your compost pile as it is composting. However, you may want to start a second pile if you have enough materials.
  • Continue adding materials to your compost pile in the winter. It will thaw and continue breaking down in the spring.
  • The best pile is made up of a variety of materials.
  • The smaller the bits of compost material, the faster the pile will decompose.

For more detailed instructions on composting in your backyard, see the how to compost in your backyard flyer (PDF).
