Developed in partnership with the Packaging School, the Knowledge Library aims to deliver the fundamental knowledge needed to make packaging more sustainable, covering both the basics of sustainability as well as deeper dives in specific issues. The library is divided into separate topics. Topics can be explored and experienced at your own pace, so choose your own adventure on the way to becoming a more knowledgable sustainable packaging professional.
