The Life Cycle of a Tetra Pak Carton
This non-comparative and easy-to-read study shows the life-cycle steps of Tetra Pak cartons for milk and juice, and the relative environmental contribution for each step. It was done by an independent research institute in Norway, commissioned by Tetra Pak in 1999, and followed the standardised life cycle assessment procedure.
