We’re beginning to compost at home and I’ve wondered myself, “What Can I Compost?” So, I’ve created myself a list that I will likely hang up on the fridge.
What I’ve been researching is that it’s important to have a healthy ratio of GREEN to BROWN materials. I haven’t continually read a consistent ratio, no perfect recipe. I like baking so I’ve been looking for that perfect recipe or exact science. What I’m figuring out is that it’s going to take some experience. I’ll let you know what I learn. Here are the ratios I’ve read so far:
- Equal Parts
- 25-30 parts Carbon (Brown) : 1 part Nitrogen (Green)
- “Much more carbon than nitrogen”
Green:
Greens are nitrogen-rich. Have lots of moisture and break down quickly. Create heat. Too much nitrogen will end up with a stinky pile.
- Fruit and vegetable peels
- Citrus rinds
- Melon rinds
- Coffee grounds
- Eggshells
- Tea leaves and paper tea bags
- Old vegetables that have gone bad
- House plant trimmings
- Weeds
- Grass clippings
- Fresh leaves
- Deadheads from flowers
- Dead plants (not diseased)
- Seaweed
- Cooked plain rice
- Cooked plain pasta
- Stale bread
- Corn husks
- Corn cobs
- Broccoli stalks
- Sod
- Thinning from vegetable garden
- Spent bulbs
- Holiday greenery from wreaths and swags
- Stale herbs and spices
Brown:
Browns are carbon-rich. Break down slowly, so should chop them up small. Adds aeration. Too much carbon with slow down decomposition.
- Shredded newspaper
- Shredded office/ school paper
- Shredded non-glossy junk mail
- Torn up plain corrugated cardboard boxes
- Straw
- Bedding from hamsters, rabbits etc.
- Fall leaves
- Chopped twigs and small branches
- Pinecones
- Nutshells (except walnuts)
- Used napkins
- Tubes from toilet paper, paper towels, or wrapping paper
- Fallen birds nest
- Pine needles or straw
- Used paper coffee filters
- Pressed paper egg cartons (torn small)
- Saw dust (untreated wood)
- Brown paper shopping bags, shredded or torn
- Brown paper lunch bags, shredded or torn
- Leftover peat or coir from seed starting?
- Coir liners for hanging baskets
- Wood chips
- Bedding from chickens
- Items labeled BPI Certified Compostable
- Items labeled ASTM D6400 or D6868
- Pizza boxes
- Pet food
What NOT to compost:
- Meat, fish, egg, poultry scraps (odor and pests)
- Dairy products (odor and pests)
- Fat, grease, lard, or oils
- Coal or charcoal ash
- Diseased or insect- ridden plants
- Pet waste
- Yard trimmings treated with pesticides
- Black walnut tree leaves or twigs (harmful to plants)
- Recyclable materials
- Items labeled biodegradable
- Items labeled Oxo-biodegradable
- Hair or pet fur
- Aluminum Foil
- Cigarette butts
- Dental floss, Q-tips
- Plastic
- Styrofoam
