Tom Szaky wants to be the rag-and-bone man to the world, collecting the  rubbish no one else wants – cigarette butts, razors, expired pills and  plastic food wrappers – and turning an enormous profit by finding new uses  for it. His US-based company TerraCycle already has rubbish collecting and re­cycling  operations in six countries and expects to launch in 11 more (including  Japan, Australia and Sweden) in the next year. He launched TerraCycle in  Britain last September and in Ireland this month. 'We’re just a $40 million company at the moment,’ he says. But he plans to  become the Google of garbage. 'A billion-dollar company doesn’t seem that  big… why not!’
