Plastics have a role to play in achieving the circular economy model and at the same time this should be done safely: the European regulations ensure that recycled plastics are as safe as new plastics.
What we deal with here is the so-called issue of ‘legacy substances’. This means that an additive that was legally approved for use in plastics 10 years ago can, either be banned or restricted for certain uses today. When a product containing such an additive becomes waste, its potential recycling depends on whether this additive is still allowed in recycled products or not, while specifying under which conditions.
Here are some examples of “legacy substances”:
Therefore a substance of restricted use may still be found in a recycled product.
