Kupa Inc., manufacturer of carbide bits and electric files, was recently recognized by the Environmental Protection Agency as being a recycler and not a waste producer. Kupa has been manufacturing its own and since 1999 to meet growing demand for the carbide bits. Kupa Precision Carbide are cut by machine at the company’s Buena Park, Calif. facility using oil as a lubricant. According to Richard Hurter, marketing director. they recently purchased two new oil filtration machines that circulate the oil in order to filter out the carbide sludge. The newly cleaned oil is returned to the machine, allowing them to make better cuts. The carbide sludge is collected in a container and is sold back to carbide recyclers. So instead of producing waste, Kupa is now a recycler. Way to go, guys.
