World of Coal Ash after a three (3) year hitaus retunred on May 16-19, 2022. Some 1,057 participants, falling just shy of previous WOCA attendance records, despite smaller-than-usual numbers of attendees from countries still struggling with COVID travel restrictions. Ultimately, 397 abstracts were submitted and 245 presentations were delivered during the conference.   Craig Heidrich, CEO of the Ash Development Association of Australia who has attended every WOCA since 2003, recalled at his first WOCA conference, just 97 papers were presented.  A small contingent of Australian's attended the conference sharing some perspectives on research into coal combustion products we have been doing douwn-under.  

• Pavement Innovation down-under, CCPs rigid and flexible pavement applications 
• Global opportunities and challenges for coal combustion products with a Circular Economy
• Standard Specification for Low Carbon Concrete using Fly Ash and Slag

A packed exhibit hall and new features like the Technology Showcase kept attendees busy in between concurrent technical presentations on a wide range of topics. Social events including an Ohio River riverboat cruise provided a welcome return to industry socializing.

American Coal Ash Association and the University of Kentucky Center for Applied Energy Resources should be thanked for again staging an excellent conference for sponsors, exhibitors, and attendees and making WOCA 2022 such a success!
