constitutes of course, the main constituent of shellfish as well as other marine group’s skeleton. Furthermore, the process of lime precipitation can be triggered by the metabolism of bacteria and other micro-organisms. One microbial process is at the source of about %40 of the world chalks (calcite) cliffs, in addition to the remains of calcareous plankton. CO2SolStock is studying a variety of such microbial processes to be found in natural habitats as a potential tool for carbon sequestration. In this paper, we will confront the CCS and biomimetic approaches, both from a theoretical point of view and from the already available data. Amongst the parameters to be compared are the types of carbon source, the energy demand, the stability of the sequestered carbon, the mass balance and flows and the up-scaling challenges.
