Made from unbleached bamboo paper, an annually renewable resource. These bowls require no trees to be cut down in order to make them, plus they have a bio-lining made from plants. Great for delis, grocerants and restaurants serving takeout. These bowls work for hot or cold foods and show a commitment to environmental responsibility. These disposable bowls contain no wax or plastic lining, and are freezer safe. They are certified compostable in a commercial facility, which may not exist in your area.
