“The ground energy state of carbon
is a mineral carbonate”
Olivine:
Mg2SiO4 + 4CO2 + 2H2O => 2Mg2+ + 4HCO3
- + SiO2
Mg2SiO4 + 2CO2 => 2MgCO3 + SiO2
[∆H = -239.2 kJ/mol]

33. Paper application
1st Tests:
CO2 Cleanup paper
University of Darmstadt
Prof. Schabel:
”The optical properties are better
that I expected. The retention in
the paper is quite good”
”But for a first ”shot” I would rate
the results better as positive”
24-06-19 ICCDU Aachen 33
Goal: Replacement PCC

34. Polymers
Goal: Replacement: Lime/ Wollastonite

36. Take home message
1. Make the unknown more known: Mineralisation
CCU, Negative CO2 emissions
2. Look for symbioses (not only CO2)
Ambient: Replace existing civil products
(extra CO2 savings life time)
Accelerated: Manufacture products, products
(and store CO2)
CO2 reduce, re-use & remove
