First look inside Cardiff's Viridor waste incinerator

Wales' first modern incinerator is in the process of testing its technology. It could burn up to 350,000 tonnes of waste a year.

The plant will burn black bag waste from five local authorities in south east Wales, as well as commercial waste from the private sector.
