How is a Tetra Pak carton recycled?
Tetra Pak cartons are primarily made from wood fibre that has been refined into paperboard. To this, are added protective layers of polyethylene and aluminium.
Used cartons are not waste. They are a valuable raw material for useful new products.
As Tetra Pak cartons are made largely from virgin wood fibres, they are an especially valuable paper source to recycle. The fibres are long, strong and can be used again several times. Cartons usually go to paper mills after collection and sorting. In the mill they are mixed with water, either separately or with other types of paper, to create paper pulp. During this same process, the plastic and aluminium is separated from the pulp. The pulp is used to make new paper products, e.g. corrugated board, tissue paper and notebooks. The remaining mix of plastic and aluminium can be processed like a composite plastic material to produce products such as roof sheets, pallets and panel boards
