What has a PET bottle to do with a babywearing cover or jacket? A lot – at least in case of our manduca by MaM babywearing covers. We are talking about upcycling, the creative utilization of “waste” by turning them into new products. Combining resource conservation with creativity, upcycling has been a trend for some years. The producers of our manduca by MaM babywearing cover and jackets, too, have become upcyclers: For some of their products they use PET bottles in the production process.
