Cement Industry Environmental Consortium

• The CIEC is a non-profit corporation organized in
  1985
• Members include cement companies, air districts,
  and utilities
• Mission Statement is to
• a. undertake research relating to environmental
  issues affecting the cement manufacture and
  supporting industries
• b. implement those developed technologies

CIEC Research Commercialization

• Biosolids
• NOx Reduction
• Alternate Materials
• Recorded values below 2 lbs NOX per ton of
  clinker
• Cement Kiln Dust Utilization by Kiln
• Reuse
• Alternate product development
• Reduction in generation rates

CIEC Research Commercialization

• Alternate Materials
• Mining waste
• Potliner waste
• Cyanide waste
• Fly ash
• Slag
• Tires
• An alternative fuel
• For NOx reduction

5
Cement Industry Environmental Consortium

• California Cement and CO2
• California largest producer of cement in US
• California largest importer of cement in US
• Most cement companies foreign owned
• Average plant produces 1 million tons cement/yr
  (11plants producing 13 M tons)
• Each ton of cement produces 1 ton CO2
• 40 CO2 from fuel 60 from chemistry

6
CO2 Emissions from Cement Kilns

• Cement consumption projected to grow, so CO2
  output will grow
• No concrete without Portland Cement
• Approximately 15 cement in concrete
• Plants need to be located at mineral sources
• Today Californias cement demand is very high,
  creating unprecedented delays in construction

7
Cement Industry Environmental Consortium

• Carbon Capture and Reuse Project
• Potential project identified in 2001
• Initial evaluation by Technology Committee
  indicated possible reuse applications for
  recovered CO2 Oil fields and fertilizers
• Current amine recovery systems determined to too
  small with recovery too costly plus capital on
  order of 100 million dollars

Cement Industry Environmental Consortium

• Carbon Capture and Reuse Project
• Potential for concurrent reduction of
  conventional pollutants if CO2 recovered
• The CIEC received a 70,000 grant by the MDAQMD
  to undertake an initial solicitation, review of
  received proposals, and to develop additional
  funding sources

11
Cement Industry Environmental Consortium

• Carbon Capture and Reuse Project
• CIEC members made a presentation to the ARB, with
  CEC staff present, soliciting funding
• CIEC has attempted to identify funding sources
  from DOE (grants)
• DOE has directed us to the Regional Partnerships
• CIEC not opposed to request congressional funding

12
Cement Industry Environmental Consortium

• Carbon Capture and Reuse Project
• The CIEC CO2 project differs from that of the
  Portland Cement Association
• Capture and reuse vs. fuel economy and admixtures
• Very promising line of inquiry that doesnt seem
  to fit available RD funding boxes. A square
  peg in a world of round holes
• We are still looking for funding!

13
Cement Industry Environmental Consortium

• Carbon Capture and Reuse Project
• Response to the solicitation
• 37 specific projects received
• 25 proposal teams
• 7 proposals selected for interviews
• 2 recovery technologies selected
• 2 awards made for theory validation
• Temperature Swing Adsorption
• Enzymatic Recovery

14
Cement Industry Environmental Consortium

• Carbon Capture and Reuse Project
• Generic Types of Responses
• Waste heat conversion to electric power
• Reduce emissions via plant audits
• Treatments for flue gas
• Change fuel or cement chemistry
• Conversion of CO2 to salable products
