H eritage patented a process for stabilizing K061 Electric Arc Furnace (EAF) dust. We used this technology for years to de-list the EAF dust, allowing it to go to our non-hazardous landfill at a reduced cost to the customer. EAF dust is the largest, listed solid hazardous waste in the U.S., approaching one million tons per year. The current method, at the time, for treating EAF dust, involved landfilling or partially recycling the EAF dust. Since neither of these two options were viable or sustainable solutions, Heritage was determined to find ways to recover valuable metals out of the EAF dust and recycle/reuse 100% of the EAF dust.

Then, about two years ago, Heritage patented a process and built a demonstration plant to prove that the dust could be 100% recycled. The benefit of the Heritage PIZO (Pig Iron Zinc Oxide) process is that it converts generators' waste into viable products. Heritage's PIZO Process also removes generators from the RCRA liability of EAF dust.
