These three materials are layered together using heat and pressure to form a six layered armour which protects the contents from light, oxygen, air, dirt and moisture. Furthermore Tetra Pak cartons are lightweight, easy to transport and fully recyclable. The aseptic technology allows the product inside to stay fresh, without the need of any preservatives. The pack need not be refrigerated until opened.
Tetra Pak cartons are recyclable. The paperboard (which is 75% of the carton) is recycled into paper products and the 25% remaining fraction (consisting of the polyethylene and the aluminium) can be recycled into panel boards, roof sheets and so on.
Once the collected cartons are sorted and baled, they are sent to the recycling plant where the paper is separated from the polyethylene and aluminium via the hydra pulping process and then converted into many useful products.
Used Tetra Pak cartons are already being collected and recycled in India for the past decade and more. Currently, we estimate that around 50% of all used Tetra Pak cartons are being recycled, as verified by The Energy & Resources Institute (TERI). Read the report. Tetra Pak seeks to continuously educate all sections of the recycling value chain (consumers, waste traders, waste pickers, recyclers) that used Tetra Pak cartons are recyclable and that they have a good value.
Tetra Pak packages are primarily paper-based and recyclable. A number of Life Cycle Analysis (LCA) studies have assessed the greenhouse gas emissions from different packaging formats (including glass bottles, PET and HDPE containers, Tetra Pak cartons, metal cans and stand-up pouches) and the Tetra Pak carton is generally attributed with the lowest environmental impact. The Tetra Pak package is primarily made of paperboard (75%), which has a low carbon footprint, as its main raw material – wood fibre, if well-managed, is renewable.
