Summary and outlook Stainless steel in the triangle people-planet-profit

Summary and outlook Stainless 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 more

sparingly, develop less polluting technologies for food, water and energy production technologies high in stainless steel

less
