The Secret World of Your Rubbish

The aptly named Crapper and Sons run a landfill site in Wiltshire where they oversee the disposal of more than 200 trucks of waste a day. But with space running out and landfill losing favour, the father and son need to find new ways of keeping their rubbish dynasty alive. The film also follows two technicians at a sewage works in west London, who have the unenviable task of removing the wet wipes and other rubbish that gets flushed down people's U-bends, and a team of litter collectors at Marylebone Station.

The waste disposal and recycling documentary follows the work of staff at Dungeness A, a decommissioned nuclear power station in Kent, who have to adopt extreme measures to maintain the site. At the other end of the spectrum are the security team at Stansted Airport, whose job it is to sort through wheelie bins full of prohibited items removed from passengers - with everything from Marmite and motor oil to dead rabbits turning up in hand luggage.

The documentary visits a waste facility in Nottingham which offers an alternative to landfill, burning rubbish to create energy for surrounding homes. It also follows the work of a Glasgow father and son who recycle some of the hundreds of thousands of tons of clothing thrown out every year and the team at Motorpoint Arena in Nottingham, cleaning up after a heavy metal gig.

The work of the rocket scientists at the University of Surrey Space Centre, who are researching how to remove the hundreds of thousands of space junk orbiting the Earth's atmosphere at 17,000mph, which could do catastrophic damage if they were to collide with a satellite. Also, a specialist waste disposal team tackles asbestos which, despite being banned more than 20 years ago, remains the leading cause of occupational death in the UK, and glass thrown into a bottle bank is recycled as a jam jar.
