Wheatstraw is the remaining plant fiber after the grain (which stores the proteins and allergens) has been removed. *Though these compostable plates are soak proof, hot items will cause the plates to "perspire" and some condensation will form at the bottom.

Our plant fiber products are guaranteed to break down in 2-3 months in industrial facilities. Please check locally, as the facilities are not available in all communities.
