A Guide to Compostable Bags and Serviceware
We know you want to do the right thing, and we know that it can be confusing. With all the different products out there, how do you know if you are buying the right ones? Take a moment to read our guidelines. If you still have questions, do not hesitate to send us an email.
If you are ever unsure, your safest choice is to use a certified compostable product. You can browse the Biodegradable Products Institute catalog to confirm whether your product is “certified compostable”.
Sustainable Materials Management, Inc. accepts food soiled paper products. These paper products do not have to be certified compostable, but must adhere to the following guidelines:
Food soiled paper or cardboard (pizza boxes, paper clam shell boxes, etc.)
“Certified Compostable” products.
Bagasse, wheat straw, bamboo, etc.
Glossy paper (magazines)
Wax coated paper
Plastic lined or coated paper
Sustainable Materials Management, Inc. accepts all food-safe wood products. If they are safe for food, they are safe for us.
Sustainable Materials Management only accepts certified compostable plastics. These certified compostable plastics must be easily distinguishable from their non-compostable counterparts. For example: a compostable clear plastic cup must have some marking (a green line) that makes it easily distinguishable from a regular plastic cup.
Plastics: Compostable vs. Biodegradable
What’s the difference? Why does it matter? It matters because the material we accept affects the quality of the compost we produce. We will not risk the quality and safety of our compost product with untested products.
