Circular construction continuously strives to repurpose and reuse buildings and building materials. A new building should therefore be constructed largely from recyclable materials and be easily deconstructable. For example, constructions can be dismantled at the end of their use and reused in another building. This minimises the energy end-use and significantly extends the life cycle of the buildings and materials. For wood as a building material, this means that: CO2 remains bound for longer. Furthermore, wood as a building material offers flexible construction and utilisation concepts such as modular timber construction systems. These systems allow flexible expansions and downsizing as well as uncomplicated dismantling or even rebuilding at a new location. The DERIX-Group was the first company in the industry to commit to a general take-back of its components and is thus considered a pioneer in circular construction.
