Combustion Byproducts Recycling Consortium (CBRC) Paul Ziemkiewicz, Director Tamara Vandivort, Consortium Manager National Center
CBRC Program Support • USDOE/National Energy Technology Laboratory (NETL) provides technical support regarding research priorities, technical reviews of proposals and reports and provides the program’s federal funding. • Industry and state agencies provide the program’s non-federal matching funds.
Mission Statement To promote and support the commercially viable and environmentally-sound recycling of coal combustion byproducts for productive uses through scientific research, development, and field testing
Objective To develop and demonstrate technologies to address issues related to the recycling of byproducts associated with coal combustion processes.
Advantages ofthe Consortium • Joint industry/government structure facilitates development of partnerships • Exposes committee members to variety of ideas • Projects not funded by Consortium may be supported by individual members • Spreads risk of funding “innovative” research

U.S. Department of Energy – National Energy Technology Laboratory Future Perspectives on Ash Research
2002 Survey ofCCP Production and Use(ACAA) • Fly Ash: 76.5 million tons (35% used) • Bottom Ash: 19.8 million tons (39% used) • FGD Gypsum: 11.4 million tons (68% used) • FGD Wet Scrubber Material: 16.9 million tons (17% used) • TOTAL CCPs: 125 million tons (34% used)
Getting to 50% Usage • Expand reuse in “proven” applications • Remove or reduce perceptual and regulatory barriers • Develop new or under-used large-volume markets • Greater emphasis on FGD byproducts
Expand “Proven”Applications • Concrete, wallboard, structural fill, road base • Primarily industry-driven • Develop specifications for reuse whenever possible • R&D to address specific barriers (i.e. carbon in fly ash)
Remove/Reduce Perceptualand Regulatory Barriers • DOE and EPA Role • Cooperate with each other • Encourage beneficial reuse by States • Help make public “comfortable” with CCBs • Small-volume, high-tech applications may help reduce perceptual barriers
Develop New or Under-UsedLarge-Volume Markets • Mining and structural fill applications (will require removal or perceptual & regulatory barriers) • Will necessarily be site-specific (transportation costs) • Reuse market development must be top priority for utility executives when planning new or expanded coal-fired generation capacity
