THE WORLD OF COAL ASH
WOCA is an international conference organized by the American Coal Ash Association (ACAA) and the University of Kentucky Center for Applied Energy Research (CAER). The 2026 conference is the 11th joint biennial meeting with a focus on the science, applications and sustainability of worldwide coal combustion products (CCPs) as well as gasification products.
WOCA Mail List and 3rd Party Hotel Scams
WOCA friends and colleagues: There are two organizations out there trying to take advantage of the WOCA brand. One group is selling fake attendee lists. The other is trying to get prospective WOCA attendees to reserve hotel rooms through their website. Both of these are scams. We never sell our attendee list, and the only way to reserve a room for WOCA is through our official reservation site.
