Murphy has won a £57m contract to construct a new facility in West Yorkshire that will convert human waste into electricity.
The contractor has been chosen by Yorkshire Water for treatment works in Brighouse near Huddersfield, which will process human waste to make electricity.
When completed, the new plant will receive sludge and waste water, which will then be processed over a 15-day period. Over that time anaerobic digestion occurs, a process in which the bacteria feeding on the waste produces biogas.
The biogas produced is then stored in huge containers, which can then be sold to companies to burn for electricity. The gas is also used by the facility to heat up the human waste for the process.
To carry out this process the plant will require the construction of anaerobic digesters; a new sludge reception plant; sludge thickening plant; CHP and dual fuel boilers.
