Concrete from demolitions can be used as aggregate for new concrete. Blue Phoenix can, in collaboration with the concrete manufacturer, receive concrete from demolitions, process the concrete into concrete aggregate and use this aggregate in the production of new circular concrete. Concrete from demolition of structural concrete contains high-quality stone. When used as a substitute for stabilized gravel, this high quality is not utilized.
Blue Phoenix has taken the initiative to process quality stone from demolition of structural concrete into concrete aggregate that can be reused in new, circular concrete. In this way, quality stone in structural concrete is not lost from the construction material cycle, but can be used again and again with full traceability. This is circular economy in practice and well on its way to industrial scale.
In collaboration with the client and the demolisher, the building's concrete is mapped in relation to its potential use. During the demolition, it is ensured that suitable concrete is kept separate. Suitable concrete is sent to RGS Nordic for receipt as raw material for use.
The raw material is processed into certified concrete aggregate. The concrete manufacturer uses concrete aggregates in mixing new concrete. Concrete mix is delivered for new concrete casting.
The process from mapping in the existing building to the delivery of aggregates to the Concrete producer takes place according to RGS Nordic's Factory Production Control (FPC) manual.
The new circular concrete will be certified in the low environmental and strength class with full producer responsibility.
This means that the circular concrete can be used for internal constructions that are not exposed to high loads and major environmental influences. In the past, the traceability of the old concrete has been an obstacle to using it in new concrete. But RGS Nordic has invested heavily in getting a handle on traceability, so that the circular concrete gets the right quality.
The collaboration with the concrete producer is an example of how we can get the circular economy rolling. Our goal is to replace the consumption of virgin materials for concrete production with up to 1 million tonnes over a ten-year period by recycling old concrete instead.
In this way, the circular economy for materials in the construction sector is industrialized.
Reuse and recycling are often requested and highlighted as a positive factor in a construction project, and there is increasing demand for circular concrete.

RGS Nordic and DK Beton have developed the concept and collaborate to supply circular concrete to the Danish construction sector - approved and certified high-quality concrete with full traceability.
The path towards the certification of circular concrete sales started in 2017, when RGS Nordic and DK Beton were awarded nearly 5 million. kroner from the Danish Environmental Protection Agency's Development and Demonstration Program to start a concrete collaboration so that recycling of concrete can take place on an industrial scale and thereby become available to the entire industry. This is how it can become a real sustainable supplement to standard concrete with exclusively virgin materials.
