During the 9th CEWEP Congress in Bilbao, Twence received the CEWEP Innovation Award 2018 for its sodium bicarbonate production facility which successfully captures and reuses carbon dioxide.
Project manager Andy Roeloffzen of Twence is very proud of this achievement. ‘It’s is a great honour for us’ he emphasized in his word of thanks. ‘We see this award as a reward for our vision that the development of capture and usage of carbon dioxide is necessary and inevitable to help achieve climate goals and to keep the climate change within limits. We see a pioneering role for waste-to-energy companies towards the circular economy.‘ Twence invites other companies to start the closing of the global carbon cycle in joint effort. ‘We can be a shining example for industry and society. And show that shared efforts can make a circular economy possible.’
Twence uses sodium bicarbonate (NaHCO3) in its waste-to-energy-plant for flue gas cleaning purposes. 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.’ Mr. Roeloffzen explains.
The knowledge Twence gained by developing this system is highly valuable for both the company itself, the waste-to-energy sector and for others, as Twence distributes it through among others 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 developmet of a large scale CO2 capture plant, that we expect to start building in 2020.‘ In this project again, Twence strongly focuses on the reuse of the CO2. The company uses its knowledge to 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.
