Recently, a Dutch site ‘Het Nieuwe Produceren’ published an article about CO2 usage options. Het Nieuwe Produceren is a platform with industrial progress as startingpoint. The platform provides information about developments and innovations that make the industry more sustainable, smarter and safer.
The article is mentioning ‘ CO2 usage by mineralisation’. A translated quote:
“There is also interest in CO2 as a feedstock from the construction sector. The company Ruwbouw from Harderwijk developed the so-called compensation stone. That is a new material that uses CO2 as feedstock. During the production process, the building material absorbs a large amount of CO2. For an average house this is about 5000 kilograms of CO2. The CO2 is bonded with a binder, creating a new, hard stone-like building material.”
“For building materials, mineralization of CO2 is an interesting option. That is an application that is still relatively unknown. In particular, the old mineral olivine is used here: an igneous rock that can be found in many places in the world.
During the olivine process, CO2 is removed from the air and converted into lime. By speeding up this process, it can provide raw materials. The lime can be used, among other things, as filling material in concrete, but also in paper and plastics.”
Furthermore, Wim Raaijen, the writer of the article says it would be unfortunate if CCU is not seen as serious solution for the CO2 surplus. “In the coalition agreement, there is a strong commitment to underground storage of CO2 (CCS), while nothing useful is done with it. Then CO2 will unfortunately remains waste.”
