Düsseldorf, Germany — Italian stretch blowing molding machine maker Sipa SpA partnered with Austrian recycling machine maker Erema Group GmbH to develop a way to use 100 percent recycled PET flake to produce preforms approved for food contact.
Called Xtreme Renew, the system allows preforms for PET bottles to be made entirely from post-consumer waste in a single heat cycle, which officials of Vittorio Veneto-based Sipa say is better for the environment and business.
Xtreme Renew combines Ansfelden-based Erema's patented Vacurema technology with Sipa's Xtreme technology for bottle-to-bottle recycling that uses less energy, creates less carbon dioxide and costs less to run compared to alternative systems, according to the two companies.
With Xtreme Renew, Sipa's compliance with the principles of the circular economy and commitment to the environment continues to be measurable, according to Anna Horecica-Csiki, product manager for Xtreme Renew.
"Sipa has always focused on a more reasoned consumption of PET, enabling its customers to produce lighter-weight containers, removing material where it is not necessary," Horecica-Csiki said at K 2019 in Düsseldorf.
Now the company is devoting more attention to reduce the carbon footprint of packaging, she said. Sipa collaborated with Erema to turn washed PET flake into food-grade PET with virginlike qualities for bottled water, juices, milk and ready-to-drink tea.
"Xtreme Renew lets you produce food-contact approved preforms made from up to 100 percent recycled PET flakes in a single energy cycle. That's an exciting innovation from the minds of Sipa and Erema," Horecica-Csiki said.
The use of recycled material instead of virgin PET to produce bottles in traditional processes generally lowers carbon dioxide emissions, according to the product manager. She said Xtreme Renew improves on that.
"With the new highly innovative process, emissions are cut by an additional 20 percent, and 30 percent less electricity is consumed thanks to the integration of the various phases into a single system," Horecica-Csiki said. "Moreover, Xtreme Renew can produce preforms that are up to 10 percent lighter, reduce logistics and transportation costs by 20 percent, and total cost of ownership by 15 percent."
