Waelz Sustainable Products, a joint venture of Zinc Nacional and Heritage Environmental, has proposed a new factory in Muncie that will produce zinc oxide and iron from electric arc furnace dust, which is a waste product from steel mills.

They are proposing to build on the site of the former BorgWarner factory at 5401 W. Kilgore Ave in Muncie, Indiana.

The factory would use the ‘Waelz process’ of heating the dust with a carbon source (either coal or coke) to a very high temperature and then collecting the zinc oxide out of the exhaust. Waelz Sustainable Products is proposing to process 360,000 tons of electric arc furnace dust per year, or about one thousand tons per day.
