Q: What makes Return products different from the products we now buy?
A: Plates, cups and utensils that we now buy are made from paper, plastic coated paper or different kinds of plastic. All of them take significantly more energy to make and some can be round for 1,000 years after you are through using them. Return products are made using a patented process from starch and other materials made from plants. They take far less energy to produce and can return to soil in 180 days when composted in a professionally managed facility. Return products are "the throwaway that goes away"
