Greiner Packaging is pursuing various approaches to make its packaging solutions as sustainable as possible. One course of action is to use so-called circular materials – that is, renewable, non-fossil fuel feedstocks. For the first time, the packaging manufacturer has now produced a food cup made of premium polyolefins obtained exclusively from waste and residue streams. The Bornewables line of products is manufactured by Borealis, a leading supplier of polyolefins based in Vienna, Austria.
