Extended Mandatory Deposit Approval: KHS Provides Systems for Closed Loop Recycling


With its FreshSafe PET barrier system, the Beyond Juice bottle offers a high level of product protection and freshness for sensitive drinks. Thanks to the Nature MultiPack packaging system, the bottles are held together by adhesive points which are strong and secure while being easy to remove.

  • KHS approves changes to German packaging law
  • The system provider supports the circular economy with its technologies
  • FreshSafe PET prevents contamination of the recycling loop

Dortmund – It is not surprising to learn that the majority of parliamentarians in the German Bundestag have finally approved the changes to the German packaging law. This means that the extension of the compulsory deposit to PET juice bottles will finally come into force from January 2022. Stricter regulations on recyclability and the amount of recyclate in PET bottles will also apply in the future. . This is where the technology of the KHS group comes in. The company provides proven, future-proof systems and solutions to strengthen the closed recycling loop as now specified by law, including its FreshSafe PET glass coating technology. This sustainable packaging alternative with a high level of product protection enables pure quality bottle-to-bottle recycling without contaminating the recycling loop.

“The production of designs suitable for recycling, especially for single-use PET bottles, is now even more important following the decision taken by the German government,” says Philipp Langhammer, product manager for barrier technology at KHS . However, implementing the new legal requirements is a huge challenge for all parties involved – from the retailer to the recycler. For example, PET juice and nectar bottles that may contain additives with oxygen scavengers can no longer be collected through the yellow recycling bag system but must be returned to the recycling loop. However, these additives make them more difficult to recycle than a normal PET bottle, which in turn complicates the subsequent treatment of the two types of bottles together. “With our FreshSafe PET barrier technology, a chemically pure glass SiOx interior coating, we provide an established system for this relevant problem. This makes recycling the bottles much easier because the liner can simply be washed off during the recycling process, ”says Langhammer.

Of great importance
By including previously untested PET bottles in the system, it is extremely likely that more rPET will be available for the bottle-to-bottle loop – at least that’s what many stakeholders expect. According to a 2018 study by the packaging market research institute GVM, to date around 10% of all PET bottles are still lost each year in the closed recycling cycle due to limitations in the recycling process. compulsory deposit system. This represents around 40,000 tonnes of plastic per year that cannot be reused to make food packaging. According to Langhammer, the extension of the compulsory deposit system is therefore a leverage factor that can be used to further increase the average amount of recyclate in PET bottles. This not only promotes sustainable processes, but also increases consumer acceptance of this material. In addition, bottle-to-bottle recycling offers a number of carbon footprint benefits, Langhammer says. “RPET has a balance that is up to 60% better than the new material in this regard.” Therefore, KHS welcomes the changes to the German packaging law.

With its environmentally friendly packaging and resource-efficient machine technology, the system supplier helps its customers to make their production processes ever more sustainable. KHS packaging experts believe it is important to effectively close the recycling loops. The InnoPET Blomax V-series PET stretch-blow molding machine, for example, processes preforms made from 100% recyclate. If necessary, it can be supplemented with the digital and automated Unit Mold Control system which can better regulate the variance of rPET, among others. Another eco-friendly option from KHS is the 100% recycled Beyond Juice bottle concept with a FreshSafe PET liner in combination with KHS Nature MultiPack, a container system that holds the bottles with adhesive points that are strong and secure but easy to remove. This reduces the amount of packaging waste by up to 90%. All KHS shrink wrappers can also process fully recycled film. “We are continually developing our technologies for the sake of sustainability and consistently support the idea of ​​the circular economy,” says Langhammer.
