Stadler UK, one of the main project contractors at AmeyCespa’s mechanical biological treatment (MBT) plant in Waterbeach, opted to install the latest in sensor-based sorting technology from Tomra Sorting.
It is the first time in the UK that a TiTech XRT has been applied to recover inert material from fines.
AmeyCespa’s refurbished plant has seen a third line added to the two existing ones, increasing the plant’s processing capacity from 45 tonnes an hour to 70 tonnes.
Four TiTech machines have been installed at the plant. Two autosort 4 units combine near infra-red and visual sensors to sort material simultaneously by type and colour. One unit sorts film while the other sorts mixed plastics.
Meanwhile, two XRT units, which use X-ray transmission, separate out the inert material – including glass, stone, ceramic and bones – from the fines on all three lines.
The recovered inert material can then be used for construction applications and any organic material left at the end of this process is suitable for anaerobic digestion.
