CRC, ECHT, Jansen Recycling Group (JRG) and Sif started the ‘DecomCockpit’ consortium to create the best and most-circular solutions for wind turbine materials and components. The DecomCockpit is a Joint Venture that, depending on the project, composes a project team that will serve as a one-stop-shop for the material management and processing. Depending on the scope, potential extra partners are included in the project team like decommissioners, manufacturers and transportation companies.



ECHT is an advice and project management company that aims to accelerate the energy transition. Within the energy transition ECHT focusses on the different innovation themes like ecology, energy, circularity, communication, human capital and transition. ECHT works on accelerating the energy transition with a positive, balanced and result-oriented approach with attention to people, society and our environment.

Within DecomCockpit ECHT takes the role to inspect & document the quality of the wind turbines, with this information and the input of DecomCockpit partners, a plan is written to re-use, repurpose, or recycle the components of a wind turbine. ECHT also, takes the lead in finding partners that can re-use components and aims to have the best economical and material solution for the wind turbine components. Next to that, ECHT has the capability to assist the asset owner in roles like decommissioning project, quality, construction, or contract manager.


Jansen Recycling Group

As a metal-processing company, it’s our challenge to reduce the amount of (production) waste. And so to deploy residual waste flows as directly as possible as a secondary raw material for smelters. Jansen Recycling Group plays a leading role in this for ferrous and non-ferrous materials. Our role starts directly at the source, so that your production process runs optimally. We give you complete peace of mind and that cutting edge versus your competitors, with internal custom logistical solutions, transparency in material valuation and risk management.

Within DecomCockpit Jansen Recycling Group is in the position to accept, process and trade wind turbine components that are not suitable for re-use, repair or refurbishment. Bigger parts will be reduced in size safely by the JRG with various optimized techniques. The materials are further processed, sorted, and stored at 2 locations in the Rotterdam area that have high-end sustainability standards and are easily accessible by road and vessels. The SHE-Q system accounts for a safe environment and high quality of sorting. JRG has such a high quality of sorting and processing that smelters can use this as secondary raw material in their processes, to make new material for e.g. new wind turbines.



CRC is engaged in recycling of thermoset composites. CRC offers a sustainable solution at a lower purchase price than regular waste management companies. The system that CRC developed consist of a material sorting system, mechanical grinding and chemical processes.

Using mechanical processing CRC can create custom sizes of fiber feedstock from course to fine, which make up about 70% of the waste stream. This feedstock consists of glass and/or carbon fibers and is highly suitable for making new products. It can be remanufactured in endless functions: currently CRC is making various feedstocks that can be used as a basis in the construction and infrastructure industry. Next to that there is a test in progress in which the composition of the product is mixed with thermoplastics so that it becomes suitable for the injection moulding and 3D printing. But also, we can use the feedstock to make new bridges and materials for new buses. The options are (nearly) endless.

The other 30% consists of resin dust and can be turned into nafta through a chemical process. This nafta can be used as a raw material for new plastics. Another big advantage is the CO2-savings that come from reusing the recycled composites in new products.

Within DecomCockpit CRC is responsible for the recycling of the composite components that cannot be repaired, refurbished or repurposed. Also, CRC is, together with our clients, thinking about how to design and create new products that our clients can use themselves to close the circular loops. The manufacturing of the new products is outsourced to partners of DecomCockpit.



Founded in 1948, Sif is a company with a solid track record. From a purely manufacturing company of large, thick tubular steel structures, the company has transitioned towards a total solution provider of offshore wind monopile foundations. Today Sif employs over 600 people (approximately 50% of whom are on the payroll) at two manufacturing sites in the Netherlands: Roermond and Maasvlakte 2, near Rotterdam.

Sif continuously strives to optimize its assets to meet market demands; Developers of offshore wind farms and EPCI contractors can rely on us for foundation design, fabrication, corrosion protection, and logistics services. Sif has an active role in developing new products, and we ensure that our production processes and resources are suitable for manufacturing of increasingly large monopiles. Our employees are driven and focused on quality and want to contribute to sustainable energy. Sif offers a stimulating work environment and continuously looks for highly qualified employees, suppliers, and other business partners who share our vision: to accelerate the global energy transition.

Within DecomCockpit Sif will be responsible for the monopile recycling together with technology of the Jansen Recyling Group. Sif will send the monopile parts back to their direct manufacturers to remanufacture the steel into new monopiles. In this way we reach the highest possible circular value from the old monopiles. Also, the deep-sea quay and area of Sif will be used as temporary storage area to absorb the highly fluctuating material flow that is typical for offshore wind decommissioning.



Depending on the scope of the project we, as a consortium, are always looking for supporting partners. Our network incudes organizations that specify in ecological research, heavy lifting and transport, difficult to reach locations and much more. Inclusion of these partners is project specific and always discussed with the client. We are of course always open to look into the preferred suppliers of the client.
