Summary and outlookStainless steel in the triangle people-planet-profit

Summary and outlookStainless steel in the triangle people-planet-profit• People:• Environmental and health benefits due to its inert nature• More and healthier food• More efficient use of water• Planet:• The material is intrinsically durable and infinitely recyclable• It forms the basis for sustainable technologies, e.g. energy prod.• Profit:• A growing world population will require us to use energy moresparingly, develop less polluting technologies for food, waterand energy production technologies high in stainless steel
