Abstract

At present, the Tetra Pak waste cartons are brought to be disposed of in well technologically equipped paper mills, where they are pulverized. The fibre is then used in the production of recycled paper and the sandwich press of polyethylene and aluminium foil is then transported to a landfill or to an incinerator. As a progressive technology for reusing the aluminium foil as well as the energy use of polyethylene seems to be the pyrolysis. The process itself and the subsequent handling of its products require advanced risk management, both technological and economic. The article deals with the pyrolysis treatment of Tetra Pak, the properties of pyrolysis products and the possibilities of separation, which would lead to metallurgical aluminium production. The aim of the article is to draw attention to the economic potential of today's totally insignificant waste that is costly to store or burn. The reuse of material and metallurgical processing in the Czech Republic could cover 1,500-2,100 tonnes of aluminium, which represents a financial volume of at least CZK 25-30 million. The goal of the author’s team is to prove the economic potential hidden in waste beverage carton and its comparison with market value. It also aims to identify the risks and propose their management. In order to prepare the project implementation, it is necessary to compile a model including the identification of risks and the way to eliminate them.
