CCU Project (CO2 capture and reuse) permit application submitted

Mar 20, 2019

As a frontrunner in the sector, Twence makes an important contribution to the achievement of the sustainability goals of its regional shareholders. The CCU Project – the large-scale capture of CO2 and its reuse in a wide range of useful applications – is one of the strategic projects used to achieve these goals. This way waste is transformed into raw materials and cycles are closed. On 18 March, a new project milestone was reached with the submission of the Phase 1 permit application. This concerns an application for an environmental permit and a permit in the context of the Nature Conservation Act.

Sustainable greenhouse horticulture in the Province of Overijssel

Nov 20, 2018

On the occasion of the creation of the 'KKP Energieneutraal 2030' [KKP Energy-neutral by 2030] foundation on 20 November 2018, Twence explained how CO2 from its energy from waste plant can contribute to making greenhouse horticulture sustainable. Ronald de Vries, Manager Projects, explained the advanced Twence plans for capturing and reusing CO2, and the importance of this for the future.

CEWEP Innovation Award 2018 for Twence’ sodium bicarbonate production facility

Sep 20, 2018

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.’

Investigation into development of fuels from CO2

Dec 12, 2017

At the end of November Twence signed a letter of intent with technology developer Coval Energy from Breda to cooperate on investigation into the development of fuels from CO2. From 2018 we want to jointly develop and build a pilot plant to produce the ‘green fuel’ formic acid. This can use CO2 captured in the Energy from Waste plant of Twence.

Going greener through large-scale CO2 capture

Oct 25, 2017

Twence has plans to capture CO2 on a large scale from its Energy from Waste plant and make it available for useful application. This means this CO2 will no longer be emitted directly, and that is good for the environment. In September the Memorandum on Scope and Detailing, the former ‘notification of intent’ for the environmental impact assessment, was submitted to the Province. In the coming months, the Province will evaluate which questions about environmental effects need to be investigated and answered so that Twence can be awarded an integrated environmental permit for this project (the Guidelines).

Research into capture of CO2 for reuse

Aug 16, 2016

Due to the high demand for CO2 for industrial applications, but also for instance in horticulture (greenhouses), we have started researching the possibility of capturing substantially more CO2 from the flue gases of our Energy from Waste plants. This would be around 150,000 tonnes CO2 per year.

Formal completion of SBC project

Oct 22, 2014

The official opening of four sustainable projects by Twence took place on Wednesday, 22 October, attracting widespread interest. Ineke Bakker, a member of the Provincial Executive, performed the opening ceremony. All speakers, including Ineke Bakker, Geert Versteeg of Procede (a spin-off of the University of Twente) and Gert Jan Bennink of Twence, highlighted the reuse of raw materials and the reintroduction of valuable materials into the cycle. ‘The situation calls for action, not words, and this is precisely what Twence is doing.’

With the four installations Twence can:
1.    make CO2 suitable for useful applications such as flue gas scrubbing;
2. recover up to 70% more aluminium, copper, zinc and other metals;
3. process problematic green waste streams such as verge clippings more efficiently;
4. generate a greater yield from methane gas released from old landfills.

The four innovative installations show what cooperation between government, education and the private sector can lead to.

Production of own sodium bicarbonate: it works!

Sep 23, 2014

Three weeks ago the Hot Commissioning phase of the CO2NBC project started. And not without result: we are producing our own sodium bicarbonate! 

Just before the maintenance stop of line 3 – which began in week 39 – the entire system could be put into operation. This means that the required adjustments can be carried out during the maintenance stop. 
All in all, it is anticipated that full bulk production will run at the end of October/beginning of November.

The installation is steadily taking shape

May 9, 2014

The CO2/NBC installation has grown visibly over the past few weeks. 

The large tanks were delivered on Monday 31 March, after which they were immediately installed at the right location in the Line 3 flue gas scrubber. The tanks were manufactured by the firm GPI in Lopik (the Netherlands). The major installation components were connected during the maintenance break in the second week of April; construction of the platform started the week after that.

The Project Manager, Andy Roeloffzen, is satisfied with the results to date: ‘The project is running smoothly. We only lost some time during the engineering phase; however we needed that time to work out a number of elements in further detail. We do not want to make any concessions when it comes to quality and safety.’

If everything goes to according to plan, the installation will be ‘mechanically complete’ and the operating teams will have been trained by the beginning of June. The installation can then be tested.
