C2C Certified building materials for ZIN

In Belgium, CRH Structural Concrete contacted C2C Platform in 2020 to assist them in the Cradle to Cradle Certified® certifications process for products that would be used in the ZIN project.

The ZIN project will transform the former WTC towers in the north of Brussels into a multifunctional urban building. Once complete, it will be a reference for ‘making city’ in the future, setting high standards for respecting the environment and product circularity. ;

ZIN requires 95% of the products used to be Cradle to Cradle Certified. CRH thus wanted to certify their precast concrete floor and roof slabs and structural elements.

As the lead assessment body, C2C Platform assessed CRH’s products against the five critical categories of sustainability performance:

  • Material Health
  • Product Circularity
  • Clean Air & Climate Protection
  • Water & Soil Stewardship
  • Social Fairness

After a close collaboration, CRH obtained the Cradle to Cradle Certified certification at the Silver level for the following products:

  • Ergon Lier site: Floor and roof slabs (Hollow Core floor), Structural elements (Beams and columns)
  • Prefaco Lommel site: Structural elements (Stairs and landings, Beams and columns, Solid walls, Balconies, Roof slabs)
  • Prefaco Wieze site: Structural elements (Beams and columns), Floors (Shuttering slab), Walls (Double wall, Solid walls, Zeromur)

The certification is valid for two years until April 2023, around the time of the planned delivery of the ZIN building.

C2C Platform is the Cradle to Cradle partner for the overall ZIN project and continues to guide other collaborating manufacturers through the certification process.
