In Rotterdam, Pryme [CCT] is building a pilot plant at site Plant ONE that will convert plastic waste into reusable oils through an innovative pyrolysis process. The complex consists of three main parts: a closed hall with extruders, an open structure with process installations and a supporting structure for the modular energy supply.
Sustainability was central – not only in the production process, but also in the design and preservation of the steel structure. Ferris took complete engineering in-house, optimizing connections and adapting the design to the dimensions of the zinc bath. This resulted in a savings of 80 tons of steel compared to the basic design.
Tight phasing and just-in-time deliveries, including close coordination with the galvanizing plant, enabled efficient execution. The main structure was delivered in June 2022, after which another 30 tons of supports were placed in three additional phases – without affecting the preservation.
Hot-dip galvanized steel – durable protection without delay
Hot-dip galvanizing proved essential in this industrial environment. The zinc coating provides long-term corrosion protection, even with modifications such as drilling new holes. Post-treatment remained minimal, so no additional time was lost to repair work. In addition, mechanical and ENI installations could be installed without damage to the main structure.
The result is a robust, low-maintenance building that reflects this project’s core values of innovation, efficiency and sustainability. Hot-dip galvanizing not only enhanced longevity, but also construction speed – a perfect match for Pryme’s sustainable ambitions.
