Resource efficiency. Our focus on the circular economy drives the efficient use of natural resources throughout their life cycle. We improve resource efficiency through reuse, recovery and/or recycling of waste materials in our production processes and, where feasible, minimize the generation of any hazardous and other waste, and we dispose of waste using safe and responsible methods.
