Natural feel. Paper and paperboard: Paper and paperboard have witnessed a resurgence, fueled by anti-plastic sentiment and a growing global demand for designed-in recyclability. Not only is paper a naturally renewable, recyclable and compostable material, it can also add value to packaging with the appearance of “naturalness” in an increasingly eco-conscious consumer market. Mario Abreu, Tetra Pak’s Vice President for Sustainability and Chairman of the Sustainability Forum, notes that the carton giant envisions a future portfolio of 100 percent renewable materials. Tetra Pak’s packs are currently 75 percent carton, but they also incorporate polymers and aluminum, which the company wants to innovate around to establish them as 100 percent fully renewable in the near future.
