Dutch government extends restrictions on the use of steel slag
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 for the time being. The pause will remain in effect until at least January 23rd of next year. With this decision, the government wants to wait for the results of an important study.
Steel slag is a byproduct left over from the production of steel. In the construction sector, this material is often used, for example, as a foundation under roads or for reinforcing dikes. Although it is a useful material for infrastructure, there are also significant concerns about the impact on the environment.
The problem with steel slag is that harmful substances can be released when the material comes into contact with rainwater or groundwater. These substances can then end up in the soil or surface water. This is harmful to nature and can affect the quality of drinking water. For this reason, strict rules for its use have been in place for some time.
The National Institute for Public Health and the Environment (RIVM) is currently conducting research into the risks of steel slag. The government needs the results of this study to establish definitive rules. Because the research is taking more time than expected, it has been decided to extend the current temporary restrictions.
For construction companies, this decision means that they cannot yet start new projects with steel slag in locations where it is currently prohibited. The government emphasizes that the protection of the environment and public health are the highest priority at this time. In January, the situation will be reassessed based on the new scientific information.
