N2  - The Tetra Pak packaging which wasoriginally designed and developed for milk is widely used in the packaging ofmany foods and beverages. It is important to recycle and recovery of TetraPak's due to the different types of recyclable materials included 75% paper,20% polyethylene and 5% aluminum. There are serious problems in recycling ofcomposite beverage cartons that completed their lifetime and became a waste. Alarger part of this packaging waste is disposed in landfills. Therefore, ourpriority should be performing scientific studies for management of this wasteand operating with appropriate management alternatives. In this study,assessment methods and processes of waste composite drinks cartons areresearched, and an alternative way is shown which separately recovers cartons,paper, aluminum and polyethylene. Tetra Pak films were cut into over 40 mmpieces, and charged to the reactor with stirring with chloroform. Thus paper,aluminum and polyethylene dissolves in chloroform. The resulting polyethyleneand solvent liquid was transferred to distillation unit. The mixture ofaluminum and paper remaining in the reactor was boiled and stirred until itturns into a pulp. Filtration of water is ensured by waiting the pulp on thefine sieve and the percentage of remaining solid is determined by analysis atthe end of this waiting period. Thus only aluminum is remaining in the reactor.With the designed system, the waste amount of countries going to the solidwaste storage areas will decrease and the protection of our environment will beprovided. Tetrapak recovery will be a long-term economic investment. Recyclingsector will be a step more advanced. The study will also result in allowing newtechnologies and reducing raw material needs.
