Seeing steelmakers wrestle with problems of tightening US EPA regulations, landfilling restrictions and rising scrap costs led one northern Indiana steel-mill supplier to develop an impossible solution -- converting basic oxygen furnace sludge into a form that can be reintroduced easily into the steelmaking process. Even more amazing is the potential this solution has for chemical and mineral processing industries. In a team effort that included three major steelmakers, National Recovery Systems conceived of a plan to condition the sludge to make briquetting possible. Briquetting was the key to recycling because when sludge is dried enough to be charged into a basic oxygen furnace (BOF), it becomes a fine, dusty powder that would be blown away by hot updrafts long before it reached the molten steel.
