Borealis supplies sustainable polyolefin for Greiner Packaging’s PP food cup
Source:Adsale Plastics Network    Editor:JK    Date:22.Jun.2021

By using the Bornewables portfolio, Greiner Packaging is for the first time incorporating renewable resources in the production of food cups made of polypropylene (PP) with in-mold labeling (IML) as the decoration technology. Initial prototypes of the cups are available now.


The packaging manufacturer has now produced a food cup made of premium polyolefin obtained exclusively from waste and residue streams. The Bornewables line of products is manufactured by Borealis, a leading supplier of polyolefin based in Austria.


Unlike renewable raw materials produced with agricultural crops grown for food and livestock feed, the Bornewables products are made from second-generation (i.e., renewably sourced) feedstock derived solely from waste and residue streams: from vegetable oil production as well as oil waste and residues, from the timber industry, or from the food industry – for instance, used cooking oil.


The Bornewables offer the same characteristics as virgin polyolefin materials while boasting a substantially reduced carbon footprint. Also, the entire line of products has been certified as part of the ISCC PLUS (International Sustainability & Carbon Certification) system.


Greiner Packaging produces first cup prototypes made of Bornewables.

"Through this product range, we are helping our customers and the value chain achieve their own sustainability targets, maintain their existing quality standards, and provide packaging solutions that are approved for food contact," stated Trevor Davis, Head of Marketing, Consumer Products at Borealis.


A life cycle analysis initiated by Borealis at its Kallo site in Belgium, showed that using Bornewables substantially reduces a product’s carbon footprint by at least 2.7 kg CO2eq for every kilogram of polymer. Moreover, using these premium polyolefin designed for circularity reduces the depletion of fossil resources by around 69%.


The new prototype IML cups for dairy products are made of Bornewables mono-material and were developed to be recycled as normal in conventional facilities – completely in line with the principle of design for recycling. The chemical structure of the PP material used in the cups is similar to that of standard plastic and can be recycled in the same loop as conventional polymers.


"Concepts like our new IML food cups only work when all partners along the entire value chain get involved and share the same sustainability targets – from feedstock suppliers through to brand owners," added Stephan Laske, R&D Director at Greiner Packaging. "As a packaging producer, we support these efforts in the context of our own circular economy strategy and pursue new approaches alongside partners and suppliers like Borealis."
