World Centric's 6" Compostable Plates are made from wheat straw fiber, which is derived from the stalks of wheat plants (no protein, gluten, or allergens, which are contained in the grain of wheat). They're unbleached, preventing toxic dioxins from entering the environment and food chain, and easily compostable in industrial facilities or at home. This convenient set has 20 compostable plates, so there will be plenty to go around for your next picnic, birthday party, or easy-clean-up wine and cheese spread.
