This presentation describes the opportunities available to iron and steelmakers to utilize waste streams — ranging from polymeric materials to agricultural wastes — as raw materials. The potential to implement such novel recycling solutions is generally not available to many other materials industries because they operate at relatively lower temperatures. Recycling waste polymeric materials in steelmaking is one solution for end-of-life products which currently present a serious burden in landfills, as is the case with some plastics. Specifically, the lecture will present a fundamental understanding of different plastic wastes, as well as agricultural waste and tires, and their transformations and chemical reactions at high temperatures. Plant results from EAF steelmaking in Sydney, Australia, where recycling waste is now standard practice, will also be included. |
