Three pasteurisation systems made by Landia are helping Shropshire Energy produce 2.5MW of renewable energy at its AD plant in Littleport, Cambridgeshire, UK.
Designed as a free-standing unit that heat-treats organic waste so that the resulting thin substance can be used as an energy-efficient substrate, each of the three 8m3 pasteurisers at Shropshire Energy is fitted with an 11kW Landia Chopper Pump and a PODTR-I 7.5kW Landia side-entry propeller mixer.
Organic waste received at 40oC is liquefied, then heated to 70oC, before the pasteurised matter is pumped back out as a valuable raw material in closed pipes by one process to a buffer tank and then separator.
The finished digestate (8% dry solids) is BSI pas110-approved for use as a nutrient-rich fertiliser.
Any surplus electricity generated from the AD operation is fed back to the national grid to power nearby homes and businesses.
