Today, environmental issues such as recyclability are important criteria for material selection. Stainless steel objects should never become waste as they contain valuable raw materials such as chromium, nickel and molybdenum which make recycling stainless steel a valuable and worthwhile process.
In fact stainless steel production is based on recycling scrap in a melting process. One of the most important ingredients (around 25%) is reclaimed stainless steel scrap – this can be anything from your old kitchen sink to obsolete machinery. Other recycled content (around 35%) includes general industrial scrap and the remainder (around 40%) comprises new raw materials. This means that a "new" stainless steel object is likely to have a recycled content of about 60%, thus reducing waste and making stainless steel a more sustainable choice!
