Generally speaking, a one-star rating means that the product contains several materials or that substances in the product are critical with regard to recycling. However, the product may still have been produced in a responsible manner. Products made of PVC, for example, are not suitable for recycling. Nevertheless, they meet all of the legal and quality-related requirements and are produced responsibly. Migros aims to ensure that all manufactured products can be recycled in the future. However, suitable alternatives aren't yet available for all products.
