$1.5M grant to explore integrated reuse of industrial waste, CO2
February 8, 2021
Sludge, slag and other waste produced by the steel industry are not only hazardous to the environment, but can be expensive for companies to discard. A new research project led by Cornell will seek an integrated approach to turning that waste into valuable materials using a $1.5 million grant from the U.S. Department of Energy.
Steel production is a messy business. Blast furnaces reduce iron ore into pig iron, which is then converted into steel using a variety of processes and materials. Each step of the way produces a variety by-products such as flue dusts and slag – waste matter containing a mixture of chemicals and metals.
