Can I Compost It?

Any organic material will compost over time, but for the best results follow this simple recipe: 1/2 “greens” and 1/2 “browns” (by volume), plus some air and water. With these ingredients, you’ll have good, nutrient-balanced compost in no time! Here are some examples of things to compost.


Nitrogen-rich materials that are a source of protein for the microbes at work on
your pile

  • Fruit and vegetable scraps
  • Egg Shells
  • Stale bread
  • Corn husks/cobs
  • Tea bags
  • Coffee grounds
  • Plant trimmings
  • Green leaves
  • Fresh grass
  • Hair
  • Weeds (that have not gone to seed)
  • Rotted manure (no dog or cat)


Carbon-rich materials that provide energy for the microbes

  • Dried grass
  • Dried leaves
  • Straw
  • Wood chips
  • Twigs and branches
  • Paper (newspaper, shredded paper, paper towels, napkins, brown bags, etc.)
  • Cardboard
  • Sawdust
  • Grain chaff and hulls

Do Not Compost:

  • Meat, dairy, or fish (may attract animals to your pile)
  • Oil or oily food wastes (can upset the moisture balance and attract animals)
  • Dog or cat feces (may contain parasites)
  • If using a worm bin, do not include citrus or onions – these are bad for worms and they will try to escape your bin!
