This is the story of a man who struggled with homelessness and addiction, before being hit by a bold vision of ending food waste and world hunger.

The Real Junk Food Project uses the food thrown away by homes and businesses to feed those who can't afford to eat. It has saved 3,500 tonnes of food from landfill or animal feed in the last four years by redistributing it to the hungry through cafes, shops and warehouses. The project's success and potential for growth led to it being selected as runner-up in this year's BBC World Service Global Food Champion award.

Emily Thomas meets the project's founder, Adam Smith, and hears how he experienced homelessness, drug addiction, and mental health problems before embarking on this remarkable project of environmental protection and social improvement.
