Circular Plastic Economy

How can we get a place in the winners circle of the circular plastics economy?

According to the Institute for Plastics Processing (IKV) at RWTH Aachen University in Germany, a key factor is that a product should retain its value as much as possible throughout its life cycle

Reusable PET bottles are a good example: after use, they can be washed with a caustic soda solution and then refilled

Coating system: NaOH resistance enhanced

However, compared to glass, PET is not airtight, which greatly shortens the shelf life of juices or carbonated beverages

However, conventional SiOx coatings are not resistant to the aggressive caustic soda used to wash returnable bottles, IKV and KHS Corpoplast GmbH have developed a coating system that is resistant to sodium hydroxide (NaOH) that can Withstand the cleaning process

The PECVD gas barrier coating technology for reusable PET bottles has been nominated for the German Raw Material Efficiency Award by the Federal Ministry of Economics and Energy for its excellent product, process and research results

Number of recycling: from 10 to 20

The German PET bottle storage system distinguishes between single-use and multi-purpose or returnable bottles

This is mainly due to the fact that normal PET bottles can only be recycled up to 10 times, as each processing operation shortens the molecular chain

Reusable PET bottles, on the other hand, are washed with a strong NaOH solution, sterilized, and then refilled

The research project makes a decisive contribution to the multiple recycling of PET bottles in the context of the current reusable quota of at least 70% in plastic packaging legislation
.
The reusable PET bottle uses a barrier coating process, which can prevent the soda solution from corroding the coating on the one hand, and guarantee the shelf life of the content on the other hand, suitable for filling any beverage
.
According to IKV, this opens the way to fully exploit the saving potential at the resource level
