Circular economy | Aggregate Industries

We take construction and demolition waste (CDW) from redundant buildings and infrastructure to produce a recycled aggregate that can be used to replace primary aggregates. Our aim is to produce a material that can be used in the whole construction chain, not just as low grade fill material. At our asphalt plants we will take worn out roads and reuse the aggregates and bitumen to produce new
