Plastic bags are not accepted in green bins because plastic does not decompose and is considered to be trash, which does not belong in the finished compost product. At the Miramar Greenery facility, compostable and biodegradable bags also do not consistently break down, are difficult to sift out, and result in contamination that decreases the quality of compost. The finished compost should be free of contamination and of good quality for use on soils.

We discourage the use of plastic liners to avoid additional waste. If you use plastic liners, please make sure to empty the contents into the green bin and throw the plastic liner in the trash bin.
