Transforming a by-product into energy
Founded in 1925, Croda produces chemical products that are used in the manufacturing industry and by consumers worldwide. Glycerine is a by-product of one of its newer products. Driven by innovation, Croda decided to convert this glycerine into biogas for its own use through anaerobic fermentation. This results in significant savings on the cost of energy and yields a CO2 reduction of 25%.
For the installation of the fermentation reactors, Croda called on SWINN – with whom the company had enjoyed many years of sustainable collaboration in the past – and asked for structural engineering advice. The two cylindrical objects, each with a diameter of 15 metres and a height of 20 metres, obviously demand a strong foundation. None of the poles currently in place were allowed to be removed from the dam near the dike on the IJssel River, on top of which the reactors were to be installed.
Croda opted for a special vibration-free piling system with pile lengths ranging from 16.5 to 18.5 metres. The operation was, of course, coordinated with the Directorate-General of Public Works and Water Management (Rijkswaterstaat).
Additionally, SWINN created a 3D model that includes all supply and discharge cables and pipes. The designs of the pipeline bridges, landings and staircases were subsequently combined with the piping model of the fermentation reactors. This made it possible to meticulously ensure that no conflicts would arise. This clash detection is part of each 3D model made by SWINN.
After collaborating on one project, SWINN is often commissioned for the next one, as the employees have extensive knowledge of their customers’ files. Investment in collaboration and building a stable relationship are part of SWINN’s core values. As the people at SWINN were familiar with the situation at the Croda site and the building requirements, Croda could be fully unburdened with regard to the architectural and constructional development. As a result, the company was able to focus completely on its own processes and business operations during the execution of the project.
