WorldStar Award 2022 for school milk packaging made from 100% rPET

VISCONEWS ISSUE #16 ·

New year, new accolade: The World Packaging Organisation has announced the winners of the WorldStar Awards 2022. Among them was a joint project between Austria’s school milk producers and three Upper Austrian companies (PET-MAN, Greiner Packaging, and Starlinger viscotec), which involved producing sustainable cups from 100% recycled PET (rPET) to be filled with school milk for the state of Upper Austria.

Sustainability and a closed loop for plastics are front and center as we move into the new year. Since last spring, used school milk cups made from PET have been collected separately so that they could be recycled in a dedicated closed loop. And shortly before Christmas, this loop was closed for the first time. Used school milk cups collected before the fall were shredded, washed, recycled, and new rPET cups were made from the material. The first crates containing freshly recycled rPET cups have already been delivered to the school milk producers.

 

Flagship project for a circular economy

The flagship project proves that a circular economy is possible in the plastics and packaging industries. And the solution has now received a WorldStar Award 2022 in light of this accomplishment. The awards have been running since 1970 and are highly coveted, with 440 submissions from 37 countries around the world vying for the World Packaging Organisation’s stamp of approval. After picking up a TRIGOS and a Green Packaging Star Award in 2021, the project partners are proud to have their work recognized a third time with the WorldStar Award 2022.

 

“It really is great to see our efforts receive this level of acknowledgment. For us, sustainability is not just a catchphrase – it is a duty we take very seriously. Thanks to the project, as well as doing our part to advance sustainability in general, children can be taught to treat nature responsibly from a young age,” says Manfred Stanek, CEO of Greiner Packaging. Johannes Strobl, who represents the Upper Austrian school milk producers, is also delighted: “The feedback I have received from the school milk producers is that the schools are excited about the project. They appreciate the fact that the used rPET cups really are made into new cups.”

 

Starlinger Viscotec is also convinced that rPET is the ideal choice for food packaging: “Our vision is to have a process in place for collecting and recycling packaging made from white rPET,” says Herbert Hofbauer. “After all, used cups are a valuable material.”

 

Making cups from cups

The concept behind the sustainable packaging sounds simple enough, yet it is a unique proposition. Austria’s school milk producers supply schools and kindergartens directly with dairy products in rPET cups. The children consume the drinks during recess, then the used cups are gathered and returned for recycling to the school milk producers. Once collected, these cups are picked up from the farm, washed, and shredded. The resulting flakes are then cleaned and processed. As was the case for the first time before Christmas, the extruded rPET sheet is subsequently used at Greiner Packaging to thermoform new rPET cups, which are then refilled by the farmers and delivered once again to schools and kindergartens. This closed loop releases over 30% less CO2 than reusable glass bottles, which are significantly heavier. Recycling the cups also requires less energy than processing reusable glassware, for instance, and produces less waste. The reason the cups can be recycled so easily is that they are unprinted and made from 100% monomaterial.

 

rPET: material of the future

The recycling loop for rPET makes it a material with a promising future. And as things stand, recycled PET is the only post-consumer secondary plastic approved for food applications in the EU. The white rPET packaging can be reprocessed into food packaging, making it the ideal recyclable packaging solution for dairy products.
