The Directorate-general for the Environment has developed a self-test method that can help companies to prevent emissions of primary microplastics in the environment. This method has been transposed into a manual for companies. This manual allows companies to inventory their use of microplastics and to take preventive measures, either by using alternative materials or by preventing the emission of microplastics in the environment.
The manual also contains a list of sectors to which the self-test for companies may be relevant and describes for what types of microplastics the test can be used. In addition, it provides a method for evaluating the emission of microplastics, both during the production process and during the use of a final product by its consumer, and mentions some alternative materials that could replace microplastics.
