Tetra Pak beverage cartons are 75% paper, 20% plastic and 5% aluminium.
At the beverage carton recycling facility, the hydrapulper processing separates the paper (pulp) from the plastic and aluminium (Poly Al). The pulp is sent to a paper making facility, whereas the Poly Al is sent to a hot press facility. At the Poly Al hot press facility, the Poly Al mix is processed into flat panel boards. Grooves are inserted while the boards are cooling (post-hot press) to create roofing tiles. For more information on beverage carton recycling, check out From Drink Packs to Dream Homes
