The  company faced serious questions about its ability to operate under  tighter emissions restrictions in the United States, but the new process  could allow them to produce lead while meeting those standards.<\/p>\n<p>The chemical process, known as FLUBOR, represents the end of a $30  million quest to find a new way to produce lead. The technology was  patented by Italian engineering company Engitec and is easier to use to  produce copper. While also cutting on emissions, the process depends on a  reusable solution, eliminating the wasteful slag byproduct from  smelting.<\/p>\n<p>Doe Run says it will cost between $100 million and $150 million to  move the project to a commercial-sized operation. The company was not  selected last year for Department of Energy funding and last month  applied for a DOE-backed loan. They say increased funding is necessary  to move the process forward while meeting high demand for lead, which is  used in batteries (Kim McGuire, <a href=\"http:\/\/www.stltoday.com\/stltoday\/news\/stories.nsf\/sciencemedicine\/story\/4A5371F219519AE7862576EC000E8F76?OpenDocument\" ><em>St.  Louis Post-Dispatch<\/em><\/a>, March 21). <strong>&#8211; JP<\/strong><\/p>\n<p class=\"akst_link\"><a href=\"http:\/\/www.earthportal.org\/news\/?p=3223&amp;akst_action=share-this\"  title=\"E-mail this, post to del.icio.us, etc.\" id=\"akst_link_3223\" class=\"akst_share_link\" rel=\"nofollow\">Share This<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Greenwire: Doe Run Co. officials confirmed that they have successfully tested an environmentally friendly technology to produce lead, which could spell the end of smelting operations at the plant.
