PET, or Polyethylene Terephthalate, is used to package 70% of carbonated soft drinks, fruit juices, dilutable drinks and bottled water consumed worldwide. Light, durable, safe and with a smaller carbon footprint than other alternatives, PET is the most recyclable plastic in the world. It has multiple advantages over other types of plastic. First, it is a very inert polymer, which makes PET
packaging ideal for storing food, as it has virtually no interaction with the contents. It has the property of creating a barrier for oxygen and water and can be easily formed, it is highly resistant and very lightweight – perfect for beverage bottles. Also, it can be used to produce transparent bottles, which is not possible with polyethylene (PE) or polypropylene (PP). This unique material is vitally important as what our products are packaged with can have significant impacts for our environment and the sustainability of our economy [1,2].

High-quality recycling is therefore an indispensable solution for processing plastic waste. Recycling considerably benefits the environment, as new goods are replaced by recycled goods: it reduces demand for raw resources, requires less energy for processing, and reduces the quantity of plastic in landfills [2].
