Use of steel slag remains restricted in the Netherlands for the time being
The Dutch government has decided to extend the restrictions on the use of steel slag by six months. This means that the material may not be used everywhere until at least January 23, 2025. The government first wants more information about the safety of this material for the environment before new regulations are introduced.
Steel slag is a byproduct of steel production. In construction, the material is often used, for example, as a foundation under roads or in dikes. It is an inexpensive and strong material that is widely available. However, there are significant concerns that harmful substances from the slag could leak into the soil and groundwater.
The National Institute for Public Health and the Environment (RIVM) is currently conducting a major study into these risks. They are investigating the precise consequences for human health and for nature. The government considers it important to wait for the results of this study before a final decision is made regarding the use of the material.
This extension has clear consequences for the construction sector in the Netherlands. Many companies like to use steel slag because it is a form of recycling. Now that the pause is lasting longer, construction companies must look for alternative materials. In some cases, this could lead to higher costs or delays for large projects.
The Ministry of Infrastructure and Water Management will re-evaluate the situation in January once the RIVM study is complete. Until then, the strict regulations remain in force. The government's primary goal is to prevent the use of industrial waste from causing long-term damage to the Dutch environment.
