»With the Pfandring, an otherwise discarded bottle becomes a gift – for those who really need it. A common problem is convincingly solved through straightforward additive design. The Pfandring is an ecological and societal wedding ring. In the first phase it can be retrofitted to the hundreds of thousands of collection containers already in use. In the medium term it can be integrated on to the same containers in production.«
