PKN Packaging News Reports: Coffee cups have been the subject of heated debate this year – but few have stopped to consider the amount of throwaway drink trays Australians are using to carry the cups.

Mum-of-two Kate Stewart is passionate about reducing the burden of waste where she can – and has designed a reusable drink tray to address the issue in a practical way.

Her invention, Stay Tray, which is made in Melbourne from 100 per cent recycled material, is the first – and only – reusable drink tray available in Australia.
