Pant y Lladron, a Vale of Glamorgan Council facility, is on the south side of the A48 near St Hilary. The facility opened in 2008 and recycles waste material from highway gullies using a reed bed filtration system. As a by-product, clean water is produced through the reed bed filtration process. The clean water is then reused for further gully cleansing creating a semi closed loop system. Soil and other solid waste materials collected during gully cleansing are also recycled. Previously, highway gully waste material had been disposed of in a landfill site. Cardiff and Bridgend Local Authorities also utilise Pant y Lladron. Their fleet of gully suckers and road sweeper vehicles alongside the Vale of Glamorgan fleet makes up 20 to 30 vehicles regularly offloading. This creates around 2,000 tonnes of road sweeping and gully emptying material every year, and saves large volumes of water as the vehicles are refilled with the water that has been filtered through the reed beds.
