Episode 3

This episode focuses on the work of Refood, which diverts rotting food from landfill and plugs it into the National Grid. If all the food wasted by UK homes was turned into energy, it could power more than 1.2 million homes. There is also a look at Sue and John Wellfare, who have made it their mission to recycle the unrecyclable. The pair sort items by hand, from biscuit wrappers and baby-food sachets to crisp packets, and have set up drop-off points for what would otherwise end up on the ground.
