08 Nov 2018 --- Lightweight Containers BV is the founder of the innovative KeyKeg and UniKeg system. The kegs are innovative in that they are made from lightweight plastic, as opposed to steel or wood, thereby reducing cO2 emissions and costs during travel. They are also almost entirely circular: old kegs become new kegs. PackagingInsights speaks exclusively to Annemieke Hartman, Chief Commercial Officer at Lightweight Containers, on the company’s circular ambitions.
