From The Engineer:
Dunphy Combustion has recently completed construction of a carbon neutral installation which generates energy from cheese waste for a major dairy factory in Wels, Austria.
Landfrisch Molkerei approached Dunphy's engineers in Austria and asked if a design could be developed through which the whey permeate left over from the cheese making process could be turned into fuel to power the steam processing plant.
Dunphy's UK design engineers produced a dual gas fired burner that primarily uses biogas extracted from the cheese whey by an anaerobic digester. Around 1.13 million cubic metres of biogas will be produced annually, the equivalent of around 0.8 million cubic metres of natural gas.
