Using packaging that is biodegradable not only limits the drain on fossil resources but also allows biodegradable substances to enter the supply chain. The Verpackungszentrum Graz has successfully made a step in this direction by developing tubular nets using compostable Modal cellulose fibres from thinning of home forests. The nets first appeared on supermarket shelves at Rewe Austria in December 2012. 10 tonnes of plastic can be saved by Rewe alone, simply by changing the packaging for organic potatoes, onions and citrus fruit.
