Most microplastics in the Netherlands come from the worn tires of cars and trucks. This is evident from research by the RIVM, commissioned by the Ministry of Infrastructure and Water Management. The RIVM looked at where the particles are released the most and where they end up. The vast majority, 80 percent, ends up in the soil.
There is still a lot of research into how harmful these microplastics are to health. What is clear is that microplastics have a negative impact on the environment. They do not break down or hardly break down, and sometimes only become smaller to a few nanometers, which is equal to a billionth of a meter.
According to the RIVM, further research is needed into measures to reduce the emission of microplastics. The most obvious advice: use less plastic. However, in some cases, the use of plastic is less harmful or less taxing on the environment than, for example, paper or cotton.
Developing better tires that wear less can help reduce emissions. Consumers are advised to drive on tires that are properly inflated and to replace worn tires in a timely manner.
Based on this research, the RIVM will continue to look for solutions that politicians can implement.
