Green Safes eco-friendly food trays are 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 trays come in a variety of sizes, shapes, and applications. These trays are freezer safe, microwave safe, and will commercially compost within 90-120 days.
