Our 10 inch all occasion heavy-duty plate is made from 100 percent sustainable and renewable natural wheat stalk fiber and bagasse (sugarcane fiber). Gluten free and tree free. They are an environmentally beneficial alternative to Plastic or Styrofoam, which contain non-biodegradable and petroleum derived materials or paper, which manufacturing requires the cutting down of trees. They are compostable in either a industrial compost (1-6 months) or a home compost (up to 12 months). Built sturdy from environmentally beneficial natural, renewable plant fibers, they can be used in the microwave - as they are heat safe up to 200 degrees Fahrenheit - and are oil/liquid and cut resistant. Their natural tan, dye free, bleach free coloring is perfect for any occasion - picnic, barbecue, church luncheons, holiday parties and get togethers, bridal showers, weddings, carnivals, fairs or everyday use.
