There is a lot of talk about sustainability and the circular economy in the construction industry these days. But there is still a long way to go to achieve these goals. A key step in this transition is material inventory: the recording of all materials in a building before it is demolished in order to reuse as much as possible. This approach avoids waste, reduces carbon emissions and contributes to a circular economy. At Meijs Ingenieurs, we are convinced that material inventory is the basis for a sustainable future.
What is a material inventory?
A material inventory starts with a thorough examination of all materials in a building, such as ceiling tiles, window frames, glass panes, concrete and sanitary facilities. These materials are photographed, documented and checked for their reusability. Through this inventory, a demolition company knows exactly which materials are still valuable so that they can be used in other new construction or renovation projects.
A practical example of this is the Utrecht neighbourhood of Overvecht, where materials from a demolished flat were reused in the renovation of another flat in the same neighbourhood. This is a great example of local circular building: Materials that are already on site are immediately given a second life.
Why is the material inventory so important?
The reuse of building materials not only reduces waste, but also significantly lowers CO₂ emissions. In the Netherlands, 90% of construction waste is recycled, but recycling also costs energy and causes CO₂ emissions. Direct reuse of materials is therefore often a more sustainable choice than recycling. In addition, the material inventory results in a lower environmental cost indicator (EQI) and better environmental performance of buildings (MPG), which helps to achieve the stricter environmental standards for construction projects.
The role of Insert.nl
An important step in the material inventory process is the collaboration with platforms such as Insert.nl, where reusable materials can be offered and traded digitally. This creates a marketplace for reusable building materials. The platform offers architects and builders the opportunity to plan with available materials and thus strengthen the sustainable character of their projects.
Material stock at Meijs Ingenieurs
At Meijs Ingenieurs, we work daily on the inventory of materials for a sustainable future. By carefully inventorying the objects, we ensure that the materials retain their value and can be reused. Our reports not only provide information on reusable materials, but also contain CO₂ values. This makes the material inventory not only environmentally friendly, but also economically interesting for property owners and building contractors.
The material inventory shows that circular construction doesn’t have to be complicated. It starts with good insight and clear documentation of what is already there.
