Waste separation is important to ensure that the materials can be recycled more effectively. This is a good example of the Circular construction industry; Waste is the new raw material. Instead of dumping or incinerating, the aim is to give these materials a new lease on life. This is much easier when the various materials have been properly separated and the easiest way to achieve this is to separate them at the source; in other words, when they are being thrown out. Steel window/door frames, ceiling plates and glass panes, for instance, can be re-used immediately. These materials have been used, for example, in the Hive (office in Rosmalen).
You may notice this during construction, where we glue and fill materials less often (so that they are easier to remove). We also use prefab elements more often and industrialisation and work preparation are designed in such a way that we purchase exactly the right amount of material for construction, preventing new materials from going directly to waste (for example, cutting waste).
To ensure proper waste separation at the construction site, it is important that you have proper arrangements in place with the waste processing companies before the work commences. The preferred suppliers at Heijmans are PREZERO and Renewi. The framework contract with these parties states that they offer us construction site advice, at no extra cost. Construction site advice means that a construction site advisor from PREZERO or Renewi will work with the Foreman to create a waste management plan for the project. This plan includes:
While the project is ongoing.
It is important that all construction site employees place the correct waste in the correct bin/container. If, for instance, the wood container is found to contain plastic waste, the waste processing company can reject the container on arrival, or charge a higher rate to accept the container. Therefore, it is important to help each other to ensure that waste is separated properly.
