Hiding in the back of garages and garden sheds all over the country are tins of old paint.
And while some of that paint is saved for future touch-up jobs around the house, much of it ends up in landfill.
Annually, Australians throw away around 7.3 million litres of unused paint.
In a bid to divert the waste, paint manufacturers have joined forces to establish a collection and treatment service.
After one year in operation, the not-for-profit organisation Paintback has now been set up in more than 50 locations around the country.
