The most simplistic answer is, of course, because coal combustion byproducts (CCBs) must be used rather than landfilled. Our planet can not support the space needed to landfill all, or even a significant part of, our wastes.

In order to learn to use CCBs more efficiently and effectively, research results must be disseminated in a way that makes them readilly available to everyone in the field - industries, academia, governments. Information leads to innovation in industry, but it also leads to questions and ideas that can be answered only with further research.

As forums for the gathering and dissemination of information, the International Ash Utilization Symposia of the University of Kentucky Center for Applied Energy Research and the International Symposia of the American Coal Ash Association have been held biennially for many years. In 2005, the World of Coal Ash Conference was convened as a combination of both of those symposia, plus meetings of a number of other organizations, such as the U. S. Office of Surface Mining and the U. S. Department of Energy's National Energy Technology Laboratory. The success of the initial WOCA conference prompted additional conferences co-organized by both UK CAER and ACAA.

  • The complete set of WOCA 2009, 2011, 2013, 2015, and 2017 papers are represented on this site. The 2009, 2011, 2013, 2015, and 2017 portion of the Ash Library is considered as the Proceedings Archive for that conference.

  • 1999, 2001, and 2003 International Ash Utilization Symposia, and at the
  • 2005 and 2007 World of Coal Ash Conferences.

These papers are the ones for which authors have given permission for placement on this website; hence, some presentations (1999-2005) are not represented by a paper in the Ash Library.

We hope to continuously add more papers to this Ash Library Web Site, keeping this site dynamically up-to-date with the rapidly changing field.

The papers at this site are in PDF format and must be viewed with Adobe Acrobat Reader.
