Sands, sustainability by Impronta. We all have a duty to help to safeguard resources and nature. The environment is not an abstract concept; it is a living reality, which we must protect with responsibility. This is one of the concepts underlying Impronta’s commitment to sustainable development of the environment. It is from these considerations that Sands is born. Sands, the major Impronta Ceramiche project for environmental sustainability, has obtained Bureau Veritas certification that it consists of 45% pre/post consumer recycled materials.
