Eco-Products' compostable/biodegradable cups are clear and are made from an annually renewable resource--corn! With the same look and feel as clear plastic cups, these compostable biodegradable corn cups contain NatureWorks PLA, and are an environmentally friendly alternative to plastic. The cups are odorless, completely non-allergenic and biodegradable. These products are designed to compost in a commercial facility in 45-60 days.
