Disposable cutlery is often made of plastic and is not recyclable in most municipalities. Cutlery marked as "compostable" must be processed at an industrial compost facility. And even then, it may not be accepted. Some compost facilities only accept BPI certified compostables since they keep the compost up to a certain standard. Also, the sorting line moves very quickly and sometimes compostable foodware gets pulled from the compost if it looks plastic-y (as many compostable utensils do). If compostable / bioplastic foodware gets into the plastic recycling stream, it risks contaminating entire batches of plastic from resale. Buyers demand recycling to be under a given contamination rate. See China's National Sword.
