NORTH Yorkshire industrial shredding specialist UNTHA UK has helped London’s Heathrow and Gatwick airports generate 25,500kw of heat from waste food.

The Boroughbridge-based business provided the technology required for two energy recovery plants devised by food waste experts Tidy Planet for DHL.

To date, the engineering specifics of the system have remained relatively undisclosed. However, Tidy Planet has today revealed more detail behind the patented technological innovation that now tackles 10 tonnes of complex material per day.

UNTHA’S shredder sits at the front of the system and separates organic materials and reduces them to a homogenous 20mm particle size, so that they can be processed by further downstream equipment.
