The packaging of our school juices 200ml consists of several layers: paper, aluminum and plastic. The plastic prevents the ingress of moisture and keeps the juice fresh during cooling.
Most plastics are made from petroleum, a finite non-renewable resource that also pollutes the climate and contributes to climate change. From now on, the plastic used for the packaging of our school juices will no longer be produced from fossil resources but from renewable raw materials.
The bio-based polymers used are made from Brazilian sugarcane ethanol. The ethanol is dehydrated to ethylene and polymerized to polyethylene. Caps and laminating films are made from polyethylene. All these products have the same properties as conventional polyethylene and look just the same, they only differ in their raw material (petroleum or sugar cane), all other properties are identical!
The bioplastics used are not "biodegradable" or "compostable"! These decompose only under certain conditions in special plants, which are currently not present in Austria, Germany and neighboring states. In addition, biodegradable or compostable plastics massively disrupt the recycling flow of durable plastics. Therefore, for reasons of food safety and recyclability, Tetra Pak does not use compostable or biodegradable plastics.
The recyclability and actual recycling of used beverage cartons in existing recycling streams is not adversely affected by the bioplastics. The material is processed and recycled in the same way as petroleum-based polymers. Therefore, all used beverage cartons, whether bio-based or conventional, belongs in the collection containers of the Dual Systems. Do not dispose the beverage cartons with bio-based coatings and caps in the bin or compost because they are not biodegradable or compostable. Used cartons do not belong in the garbage.
In Austria, the collection of beverage cartons together with plastic packaging takes place via the yellow bin or the yellow sack.
