When wheat straw is used to make plastic, it becomes compostable and can decompose in a home or commercial site. As it decomposes at a rate similar to paper, wheat straw plastic leaves behind no toxic material, so the compost can be used for future plant growth.
You might be concerned about safety when it comes to an alternative product composed of wheat straw. The great news is that it's extremely safe! Products made from wheat straw plastic can be used in both the microwave and freezer, are approved by the U.S. Food & Drug Administration and are a non-allergen as well as gluten-free.
