Fiber bowls 16 oz. from Green Safe are eco-friendly – compostable bowls made from bagasse, which is a byproduct of sugarcane. When a sugarcane stalk is pressed and extracted the leftover material is called bagasse, a material that was once not utilized has now found a new purpose. Our bowls are offered in both natural kraft and white. The white bagasse undergoes a washing process. These bowls are freezer safe, microwave safe, and will commercially compost within 90-120 days.
