About us
WOSUP is a sustainable beverage packaging and clean tech firm based in Sydney, Australia.
Founded in 2018, by Karl Page and Martin Salter while having a couple of beers at a Sydney Swans game at the SCG.
Karl and Martin are both sports lovers and grew tired of seeing all the broken plastic and waste around sporting grounds during games. Rather than accepting it, they set about working out a solution to what is a significant global issue.
The solution they produced became WOSUP (War On Single Use Plastic).
