WHAT CAN I COMPOST?

WHAT TO COMPOST WITH US
First, let us say this is what you can compost with us, this is not necessarily a home composting guide. We are a commercial composter, our piles get nice and hot and are constantly monitored in the field. As a result of the heat we are able to maintain, our compost piles break down in 3-6 months and can include a wider variety of items.
Home composting can also be very rewarding and successful, but the items you should include in your home pile don't necessarily include what we can take and break down below. If you're interested in exploring home composting, CLICK HERE.
VEGETABLES & FRUIT
The general rule of thumb is, IF IT GROWS, IT GOES. This includes all fruit and vegetable waste. One small note, please try to remove any stickers that might be on your produce.
DAIRY, BREAD & EGG SHELLS
All bakery items are fine for composting, this includes raw dough. While you don't necessarily want to include dairy in your home composting since it might attract animals, dairy is fine for your tote. Egg shells do not need to be rinsed, just throw them in your tote.
COFFEE GRINDS & TEA BAGS
Coffee grinds and tea bags are fine to go into your tote. You can even include your coffee filters and no need to break up your tea bags, you can put those in bag, string, tag and all.
NON-MEAT COOKED FOOD WASTE
While some cooked meat is OK to go into your tote (especially from the front-of-house waste), we want to minimize the amount that we add. Try to keep this to a minimum and always avoid uncooked meats. Other food items are perfectly fine to go into your composting. If some oil is included, make sure it is vegetable oil, but try to keep that to a minimum. If you are recycling your organic waste from the front-of-house, make sure ALL serviceware is certified compostable (forks, spoons, knives, trays, packaging, and bowls). Resources can be found here, selecting CMA-W items, CMA-W Products – Compost Manufacturing Alliance.
GREASY CARDBOARD
This is the item that confuses everyone. Regular cardboard should stay with your conventional single-stream recycling efforts (paper, plastic, aluminum). Most single-stream recyclers don't want things like dirty, greasy pizza boxes, we can take those.
WHAT NOT TO COMPOST WITH US
NON-COMPOSTABLE PLASTICS
Plastic bags that are compostable are available in the marketplace. We have clients that will use compostable bag liners which are acceptable. However, conventional plastic bags are not something we want in our totes. The same goes for any plastic that you would recycle with another service, like how we recycle our plastics at home and have them picked up by our waste contractor. If it is not specifically labeled as compostable, feel free to recycle it by another means, but don't put it in your tote.
STANDARD SINGLE-STREAM RECYCLING
Single-stream is the term used for the recycling most of us are familiar with already, plastics, paper, cardboard, and aluminum. While we want to keep this material out of the landfill, it does not qualify as organic waste we will compost.
GLASS, STYROFOAM, AND PLASTIC BOTTLES
We've mentioned we don't want plastic bottles before so it sounds like we are repeating ourselves! However, it is critical that all plastics that are not compostable stay out of your tote. It is especially important to keep styrofoam and glass/ceramics out of your composting.
IN CONCLUSION
So there you have it, a general guide of what to compost with us. If we haven't said it to you already, thank you for your business and your efforts to keep food waste out of the landfill. It not only helps reduce greenhouse emissions, but helps produce compost, which has a ton of positive benefits and properties that help us maintain healthy soils!
