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. This material is often used in the construction of roads and other large projects. However, the government first wants to wait for the results of a new study by the RIVM (National Institute for Public Health and the Environment) before any new decisions are made.
Steel slag is a byproduct of steel production. In the Netherlands, the company Tata Steel in IJmuiden in particular produces large quantities of this material. It resembles stone and is very hard, which is why it was frequently used in the past as a foundation under the asphalt of new roads.
Although the material is useful for construction, there are major concerns about the environmental consequences. Specifically, harmful substances from the steel slag can end up in the soil or groundwater. In recent years, there have already been problems at various construction projects where this material caused pollution.
The RIVM is currently conducting research into the long-term risks of steel slag. The government considers it important to be certain that the use of this material is safe for both nature and public health. Until this research is fully completed, the current strict rules and restrictions will remain in force.
As a result of this decision, construction companies must remain cautious for the time being regarding the use of steel slag in their projects. The government hopes to use the results of the study to establish clear and safe rules in the future. The goal is to reuse materials in a sustainable way, but without causing damage to the environment.
