Series 1: Bonus Episode: Recycling Corrupted

Two years on from their award-winning Buried series about British waste crime, investigative journalists Dan Ashby and Lucy Taylor return to Mobuoy in Northern Ireland, where more than one million tonnes of recycling and waste was illegally dumped.

Inundated with new leads and information, they decide to follow secret waste trackers hidden in councils' recycling today. The devices lead them to startling revelations about the scale of problems in recycling. Worse still, a police file reveals suspicions that waste criminals flourished thanks to corruption.
