Yes.

While the system participation requirement pursuant to the Verpackungsgesetz (Packaging Act) and the payment obligation pursuant to the Einwegkunststofffondsgesetz (Single-Use Plastic Fund Act) apply to the same object, they operate independently. Each regulation has its own reference points, content and goals, and they function side by side without affecting one another. 

Specifically, system participation fees are used to fund the kerbside collection and recovery of packaging, while the single-use plastic fee helps cover the costs of recovering single-use plastic products from public spaces. These fees cannot be offset against each other, nor can volumes be deducted from one fee to reduce the other.
