Carbon dioxide (CO2) emissions are a major cause of global warming, which has drastic effects on our living environment. It is important to find ways of capturing the CO2 and find good utilisation for it.
Twence uses sodium bicarbonate (NaHCO3) in its WTE-plant for flue gas cleaning purposes (removal of acid components). In collaboration with other parties, Twence developed an innovative system for capturing CO2 from the dry flue gas treatment of one of the incineration lines, to use it as raw material for producing NaHCO3. It is a small cycle of significant environmental importance.
The system is fully integrated in the plant and produces approximately 8,000 tonnes of sodium bicarbonate annually. This amounts to a reduction of CO2 emissions up to 3,000 tonnes per year.
The knowledge gained by developing this system is highly valuable for Twence and for others, as it is shared through conferences and publications.
The project is supported by the provincial and the Dutch government as well as the European Union.
There are many new and useful applications for carbon dioxide. Recovery on a larger scale will help us take the next step in reuse. Therefore we initiated the development of a large scale CO2 capture plant that we expect to start building in 2020. In this project again, we strongly focus on the reuse of the CO2. We work with other parties on the development of sustainable construction materials and e-fuels with a CO2 base and the supply of CO2 as a fertilizer in greenhouses.
