School milk is now being supplied in 100 percent sustainable cups made of recycled PET (r-PET) in the state of Upper Austria. The innovation comes courtesy of a collaboration between Austria’s school milk producers and three Upper Austrian companies – Pet-Man, Greiner Packaging, and Starlinger Viscotec. This joint project is revolutionizing the packaging market and showing that a sustainable circular economy is possible. On September 16 the project partners received recognition for their work by winning a Trigos – the Austrian award for companies that do business responsibly.

The Trigos Awards are said to be Austria’s most prestigious series of accolades for responsible business and were presented for the eighteenth time in 2021. The awards aim to stimulate corporate social responsibility and sustainable innovation in the Austrian economy, while also giving credit to companies that are actively helping to prepare our society for the future. Among these were Greiner Packaging, which received an award in the exemplary projects category for its Sustainably Packaged School Milk project, alongside all of its partners.

100% r-PET – a closed recycling loop

The project, which promotes closed-loop recycling, is achieving impressive results. Austria’s school milk producers supply schools and kindergartens directly with dairy products in r-PET 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 containers are picked up from the farm, washed, and shredded. The resulting flakes are then cleaned and processed. At Greiner Packaging, the extruded plastic sheet is ultimately used to thermoform new r-PET cups, which are then refilled by the farmers and delivered once again to schools and kindergartens. This closed-loop releases over 30 percent less CO2 than reusable glass bottles. Recycling the cups also requires less energy than processing reusable glassware, for instance, and produces less waste. Crucially, the only reason the cups can be recycled so easily is that they are unprinted and made from 100 percent monomaterial.

Regional product in regional packaging

The entire school milk loop takes place within Upper Austria. The cows graze in local pastures, and the cups are filled with fresh milk at the dairy farms before being delivered to the schools. Thanks to the partnership between local businesses Pet-Man, Greiner Packaging, and Starlinger Viscotec, locally produced school milk can be supplied to kindergartens and schools in Upper Austria.

“Needless to say, we are delighted that our commitment to school milk in Upper Austria was recognized with a Trigos. The award shows that we are on the right track. For us, sustainability is not just a catchphrase – it is a duty we take very seriously. Thanks to the project, children can be taught to treat nature sustainably from a young age. After all, it makes a real difference whether we throw away packaging or whether we are able to keep recycling it. If we can help raise awareness of that, then we have done a good job,” said Manfred Stanek, chief executive officer of Greiner Packaging, at the awards ceremony.

r-PET: material of the future

The recycling loop for r-PET 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 r-PET packaging can be reprocessed into food packaging, making it the ideal recyclable packaging solution for dairy products.

Technology facts:

  • Technology: Thermoforming
  • Decoration: None – making it ideal for recycling
  • Material: r-PET

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.
