Basic principles


A lot of innovation is still required in products, systems and business models if chains are to be closed.


Smart circular systems can on the one hand be less labour-intensive and therefore require less training, while on the other hand they can be of higher quality than the 'normal' applications in the construction sector.

Example: Facadeclick developed a click system for simple and ecological construction. The joint-free façade system does not connect the bricks with mortar or glue, but with plastic inserts. The façade can easily be dismantled and reused.

Example: Systimber offers a unique way of solid wood construction. The system links wooden beams together in an innovative way to form a dimensionally stable whole, thanks to mechanical - and therefore reversible - connections. No heavy equipment is needed for the construction, which means that the system can also be used for small-scale projects in hard-to-reach places.

Example: The Step Stone project demonstrates the use of Carbstone products in Ghent. The innovative Carbstone technology produces sustainable building materials from two waste streams: steel slag and CO2.


In addition to innovation in products and systems, circular construction also demands new business models. More and more companies are choosing to offer a service instead of a product. In this way, materials remain the property of the supplier and they also remain in the chain.


  • JuuNoo researches 'walls as a service': you do not own the wall, but can rent it together with its maintenance.
  • Berg Van Termunt leases façades via Facadeclick. Facadeclick retains ownership of the materials and can collect and reuse the bricks at the end of the life cycle.
  • Groep Van Roey wants to offer the indoor climate of a space in its entirety: 'Comfort as a service'.
