Is Stainless Steel Sustainable or Bad for the Environment

Is Stainless Steel Sustainable Or Bad For The Environment

Stainless steel recycling in the UK is approximately 96 and in the construction sector itself, the recovery rate is closer to 100. The reason for the high rates of recycling is that stainless steel has a high intrinsic value. The raw materials have a high demand themselves, resulting in high capture rates of any stainless steel scrap.
