Compostable Paper Bowls with Plant-Based Waterproofing. Sustainable, renewable resources. Compostable bowls, recyclable lids. Eco Guardian's Compostable Tableware eliminates waste and the growing disposal and health concerns which may be caused by other food service items. Our new range of paper bowls step away from the traditional hazardous option of polyethylene lining used to prevent condensation/leaking and use an environmentally friendly alternative - PLA (polylactic acid) derived entirely from plants. Our range of paper bowls are microwave, refrigerator, and freezer friendly. In addition, these products are BPI certified and meet the ASTM standards for compostability. Environmentally responsible - made with managed plantations, a renewable resource. Environmentally-friendly PLA lining - made from plants, not oil. Replaces polystyrene and plastic serving bowls. BPI and ASTM Certified compostable. Approved for food packaging by the FDA and Canadian Agencies
