Food Scraps, Residuals and Waste

Certified Compostable Products

While CMA-approved compostable products are our preference, we also accept BPI-certified products. CMA conducts field disintegration testing at facilities similar to ours, ensuring that products sent to industrial compost facilities break down effectively within the production cycle. On the other hand, BPI performs thorough testing in laboratory settings. However, the results may not always translate to our windrow composting facility, requiring additional research on our part before accepting these products.

If a product is labeled as 'compostable' but is not CMA-approved or BPI-certified, please contact us to see if it's a product we can accept.

  • Tableware (forks, spoons, knives, straws, cups, plates, etc.)

  • Food containers

  • Bags
