Scrap Metal Disposal

After visiting Covanta and Ray's, I wanted to do more research on the disposal process of scrap metal, especially stainless steel.  Stainless steel scrap is very important to the production process.  According to the Australian Stainless Steel Development Association, 60% of stainless steel is made up of recycled content.  This includes reclaimed scrap, industrial scrap, and new raw materials.  Stainless steel is also unique because during its lifetime, it can be returned to its original state without any breakdown of its mineral components.  Also, because it can be recycled so often, its long life span makes it a high demand material.  Depending on country and demand, recyclers will import stainless steel and other scrap and send them to mills- either domestically or internationally.  Lastly, the fundamental components of stainless steel- nickel, chromium, and molybdenum- are all crucial for the production process.  This means this incorrect disposal of stainless steel can have large effects to the production process.  Since stainless has such a long lifetime, the effects of under use or production will not be seen until decades after the decrease in use.  It is very important to recycle stainless so it can be used to its full utility.  In 2004, China utilized 900,000 tons of stainless steel scrap in its 2.8 million tons of production.
