Brief introduction to...Kees Sinke

Kees Sinke was the project manager of Empyro and has been responsible for the construction and installation of the plant. Early December 2014 he handed over the finished installation to plant manager Martin Risseeuw.

What is your role in this project?

Since 10 years I work as independent project manager. Most of the projects I oversee are in the (renewable) energy sector. Besides supervising the Empyro plant construction, I am also involved in the installation of a district heating plant in Nijmegen and a waste incineration plant in Harlingen. My involvement in the Empyro project dates back to 2010. My focus within the project has been the construction process, which started with laying foundations in April 2014. This month I handed over the project to the plant manager, who will start-up and operate the installation.

How is the Empyro project different from the other projects you managed?

This Empyro project applies innovative state-of-the-art technology. Furthermore what sets this project apart is the skid mounted, modular construction approach. The complete pyrolysis installation has been engineered, assembled and largely tested at the Zeton workshop in Enschede. Then it was disassembled into seperate skids, transported and re-assembled at the construction site in Hengelo. Such modular approach has made on site plant construction an incredibly smooth and swift process. Everything fits perfectly because it was already mounted and made to fit in the workshop. This is truly unique. This approach allows other companies to order this installation and place it anywhere in the world.

What has been your biggest challenge in this project?

The major challenge has been the large number of contractors and suppliers. The construction of the Empyro plant was not organised as a turn-key project, so we had to coordinate many parties. This requires a lot of effort by the project manager in coordination and interface management. How all the parties collaborate is what makes or breaks a project. My role has been to create the conditions for the collaboration, to monitor progress and to remove any bottlenecks that occurred. This went exceedingly well, a truly outstanding performance of all people involved, on all fronts of the project.

What does the future hold for BTG-BTL and Empyro?

I believe BTG-BTL has developed a unique product that contributes to a more sustainable environment. It is one step forward in decreasing our dependency on fossil fuels. The product and the process are unique and offer plenty of opportunity towards the future.  Definitely also because of the skid mounted approach, which makes the plant suitable for delivery and installation anywhere in the world.

Being a part of this project has been a wonderful experience for me.

Kees Sinke: “Collaboration is what makes or breaks a project. In this case it went exceedingly well.

Bio-energy day 2014


Every year BEON (Bio-energy Cluster of Eastern Netherlands) organizes a regional Bio-energy day. The theme this year was "Bio-energy: obtained sustainably, used locally". In Eastern Netherlands, a unique combination of science centres, technology companies and renewable energy companies can be found. All parties with a strong track record in bio-energy. The mission of BEON is to increase the use of bio-energy and foster sustainable economic growth by enhancing cooperation between cluster members. 

At the end of the Bio-energy day BEON coordinator Frans Feil and BTG's Lud Uitdewilligen presented the day's findings in the form of an entertaining film. This years edition features ‘Captain Lud’ as roving reporter visiting various bio-energy projects in Eastern Netherlands,. Also covered in the film is the transport of the Empyro skids from Enschede to hengelo over the Twentekanaal (starting at 25:50 min).

Did you know ...?

  • 336 km/h is the velocity that steam sent through the 500 meter pipeline to AkzoNobel reached last month?
  • This was done in order to clean it from any possible residues from construction?
  • AkzoNobel will use our steam to reduce the amount of natural gas they consume in producing salt?

Empyro progress december 2014

As planned Zeton finished construction of the Empyro plant in early October. 

A series of factory acceptance tests was performed together with BTG-BTL engineers and Empyro operators. These tests were passed successfully.

On Monday 13 October the long awaited Big Day finally arrived. It was time to disconnect the skids and transport these to the Hengelo site.

Road transport from Zeton to the Hengelo site was expertly handled by Wagenborg.

Some of the larger skids were transported to Enschede's harbour for onwards water transport on the Twentekanaal. Footage of the mammoth transport was captured by RTV Oost

Skids were unloaded at the container terminal in Hengelo.

Once all skids were on site the reassembly process began. The image above shows the first skid being placed on the foundation.

It took only eight days of work to bolt in place all the skids that make up the Empyro pyrolysis plant. An astonishingly short amount of time.

The image above shows the placement of the final piece of the puzzle: The heat recovery boiler produced by our neighbour Stork. In November components such as the steam turbine and flue gas cleaning unit were installed. The last few weeks our people have been hard at work to reconnect all piping, electrical and control items. The image below shows the steam connection that will pipe sustainable bioheat to our neighbour AkzoNobel.

We are very proud of all the people who contributed to this achievement. It will take time for the Empyro plant to operate at full production capacity. But we know our people will continue making every effort to meet or exceed pyrolysis oil production targets.


We are glad to announce that Mr. Peter Renmarker has recently signed an agreement with BTG-BTL to be our representative for Sweden. With a background as  Master of Science in Chemical Engineering Peter started his career promoting a new energy system developed in Sweden based on a liquid coal and water mixture called Fluidcarbon, used to replace fuel oil in industrial boilers. After some years working with international marketing for SME’s in the B2B segment Peter joined AkzoNobel in -94 building up their European network of sales offices for the Wood Adhesive and Panel Board Resin Business. In 2003 he was promoted to GM for the Akzo Nobel Wood Adhesive Business in Asia based in Singapore and in 2008 he was transferred to Canada as GM/President for a newly acquired North American Industrial Paint Business within the Akzo Nobel group. Returning to Sweden in 2012 Peter started his own consulting operation involved among others in a newly started operation producing sustainable biodiesel out of waste material from the Paper and Pulp industry. We trust Peters background and contact network will be a good combination also to promote the BTG-BTL Pyrolysis technology on the Swedish market.

Financial support


To demonstrate biomass pyrolysis technology on commercial scale the Empyro project is financially supported by the European Commission under the Seventh Framework Programme (Grant Agreement 239357), by the Dutch government through the cross-sectoral programme Biobased Economy of the topsectors Energy and Chemistry, and by the Province of Overijssel via the Overijssel Energy Fund.
