Tips:

- Flatten cardboard boxes.
- Empty food and beverage containers (spatula clean or wiped clean – washing not required).
- Recycle shredded paper in a clear, sealed bag.
- Keep lids on bottles and containers.
Avoid “Wish-Cycling”
“Wish-cycling” means putting items in the recycling (blue) cart hoping they’re recyclable—even when they’re not. This can contaminate good recyclables, damage equipment, and create safety risks.
Keep these OUT of your blue cart:
- Small loose items (caps, straws, pens) — too small to be sorted; they fall through the equipment
- Contaminated paper (excessively greasy pizza boxes, paper plates, napkins) — food-soiled paper can ruin entire batches
- Non-recyclable plastics (plastic bags, Styrofoam, compostable plastics) — can jam machinery and aren’t accepted in recycling markets
- Liquids & food residue — contaminate otherwise recyclable materials
- Non-recyclable glass (ceramics, mirrors, window glass, Pyrex) — melt at different temperatures and contaminate glass recycling streams
- Hazardous items (batteries, electronics, paint) — require special handling and can harm workers and the environment
When in doubt, leave it out of the blue cart.
Green Cart Guidelines: Food Scraps & Yard Waste
Accepted Items
Put these in your Green Cart
Food scraps
Food scraps
Yard waste
Yard waste
Tips:
- Always put items in loose, not in bags.
- Cover food scraps with yard waste to reduce odors.
- Sprinkle baking soda in the kitchen container and food and yard waste cart to reduce odors.
- Additional Storage. Keep a 5 gallon bucket with tight fitting lid by your green cart. Fill that with food scraps and empty it into the green cart before you wheel it out to the curb. This keeps your food scraps contained and sealed all week and will lessen flies and odor in your cart.
Avoid “Wish-Cycling”
“Wish-cycling” means putting items in the green cart hoping they’ll be composted—even when they don’t belong. This can contaminate finished compost, disrupt operations, and create safety risks.
Keep these OUT of your green cart:
- Raw meat and raw bones — can cause odors, attract pests, and aren’t accepted in this composting process
- Compostable bags and foodware (plates, containers, utensils) — don’t break down fast enough in industrial systems and may have chemical contaminates
- Paper plates and napkins — often contain coatings or addatives that contaminate compost
- Dirty or waxed paper — can contaminate compost and won’t break down properly
- Excessive dirt and soil — adds weight (can break cart or damage trucks), reduces compost quality, and can interfere with processing
- Pet waste, diapers, and hazardous materials — pose health risks and must be disposed of separately
When in doubt, leave it out of the green cart.
