Circular economy in construction

Circular economy throughout building life cycle

Circular economy can be implemented throughout the entire construction life cycle, from land use planning to the demolition and the recycling and reuse of materials.


Circular economy minimizes environmental effects 

In a circular economy, materials should be used for as long as possible, thereby generating as little waste and emissions as possible. In other words, in a circular economy, the aim is to preserve the value attached to materials in society for as long as possible. The circular economy is often associated with recycling alone. Keeping materials in circulation is essential in a circular economy, but a circular economy can be implemented throughout the entire life cycle of construction, from land use planning to demolition and from there to recycling and reuse of materials.


Circular economy stages in construction

Building use, maintenance and renovation

The building is used correctly, users can contribute to the implementation of the circular economy through their own actions. During use, digital platforms are used to promote services such as renting, borrowing and sharing. Repair and maintenance ensure the longevity of buildings and building components.

Demolition / removal of building components

If, despite renovation and maintenance measures, a building must be demolished, efficient recycling and reuse of materials is ensured so that the demolished building serves as a material bank for new buildings.

Land use planning

Land use planning ensures that planning regulations support the implementation of the circular economy and generally determines whether to design completely new and save the old.

Implementation planning

The design of old buildings aims to save a lot of old. The design of new buildings takes into account, among other things, circular economy materials and reuse, multi-use, flexibility of transformation, repairability, demountability of structures, modularity and portability.

 
 

Manufacturing of building materials

Materials product development takes into account the durability, repairability, maintainability, recyclability, and scarcity of virgin raw materials. The materials utilize side streams to reduce the use of virgin materials.

Construction and logistics

Waste is prevented by sorting and recycling. Construction site operations take into account the principles of the circular economy.
