ACEME 2015

ACEME logo Fifth International Conference on Accelerated Carbonation for Environmental and Material Engineering (ACEME 2015)

ACEME aims to discuss the latest advances in theoretical and applied research on accelerated carbonation of various natural and industrial residues.  This emerging field addresses the conversion of CO2 to carbonates and how they can be used for various applications such as building and construction materials or fillers.  Professor Alissa Park, director of the LCSE, and Professor Klaus Lackner of Arizona State University, former director of LCSE, were co-chairs of the ACEME 2015.  It was held at Columbia University from June 21-24, 2015.  The topics discussed included principles and kinetics of accelerated carbonation of alkaline materials (including industrial wastes, lime, cement and concrete), utilization of the carbonated materials, and pilot and full-scale applications.  Participants from across the world including Canada, UK, Taiwan, Australia, Switzerland, The Netherlands, Belgium, Italy, Estonia, Scotland, Mexico, UAE, China, Finland, Spain, Granada, South Korea, and USA attended the conference.

Topics from ACEME 2015 covered:

Principles and kinetics of accelerated carbonation:  The fundamentals of reaction kinetics and mechanisms of various carbonation schemes in both natural and engineered systems.  Topics also included thermodynamic and kinetic modeling as well as mineralogical and morphological transformations.

2. CO2 Capture and storage by mineral carbonation: Carbonation of minerals, rocks, soils and sediments in terms of carbon capture and storage.  Topics included chemical and morphological alterations in minerals; the stability of carbonated materials; the evaluation of CO2 storage capacity; mineral carbonation as an alternative direct air capture method, and other novel in-situ and ex-situ mineral carbonation technologies.

3. Accelerated carbonation of alkaline materials including industrial wastes, lime, cement and concrete: Carbonation of alkaline materials such as industrial wastes and cementitious materials.  Topics included identification and resource estimations; reaction kinetics and mechanisms; implication of feedstock heterogeneity on carbonation behaviors; chemical and physical characterization of carbonated materials including their potential environmental impacts upon disposal or utilization.

4. Utilization of the carbonated materials: The potential uses of carbonated materials (both minerals and industrial wastes) as well as their byproducts.  The evaluation of carbonated materials in various applications were discussed (e.g. construction materials, paper and plastic fillers) in terms of their performance (e.g. mechanical and compressive strengths) and chemical and physical stabilities.

5. Pilot- and full-scale applications: Case studies of pilot, field or commercial-scale accelerated carbonation technologies (including CO2 injection into reactive geologic formations) in the context of carbon capture and storage, treatment of industrial wastes, and utilization of carbonated materials, etc. Novel reactor design, process optimization, heat and materials integration, and life cycle economic assessments were all relevant topics.
