Petainer, a supplier of PET preforms to Carlsberg's DraughtMaster system, has been invited by the Carlsberg Group to participate in the Carlsberg Circular Community based on the Cradle-to-Cradle design framework; a unique and ambitious upcycling programme designed to eliminate packaging waste. Carlsberg has invited suppliers to take part in the new initiative, which is based on the idea of creating packaging that is optimised for recycling and re-use - an approach, often referred to as "upcycling." The cooperation has been formalised through the Carlsberg Circular Community, for which Petainer has been invited to participate as a founding member and the only current PET packaging supplier. Under this initiative, Carlsberg aims to have new products undergo an assessment for "upcycling" potential using a Cradle-to-Cradle analysis, which will reveal if the products contain any chemicals or additives that would reduce the value and quality of the materials.
