Paperboard Milk Cartons


Updated on November 8, 2019



Make sure it's empty and rinsed-out. Remove any plastic spouts, threaded caps and/or tabs. and place the carton in the green compost cart. The plastic spouts and caps go in the gray cart (too small an item). These containers may have a thin plastic layer laminated to the paperboard, as a liquid barrier. The paper is still compostable, and the industrial composter will determine what to do with the tiny amount of plastic, after the paperboard has broken down.


Opt for milk in a recyclable (or reusable) glass bottle.


Cartons are a mix of paper and a thin layer of waterproof material (either wax or plastic), but they will breakdown appropriately during industrial composting.
