"A Canadian company is creating an alternative green fuel from a new source of energy that was under our noses all along - human sewage.

Scientists at biofuel group Dynamotive say the oil produced from human waste can be used instead of fossil fuels to generate heat and power in diesel engines and boilers. They have successfully carried out the transformation on a pilot scale and are looking at ways to scale up the process to commercial quantities.

Andrew Kingston, president and chief executive officer of Dynamotive, said: "There are no process issues at this point to stop us using human sewage sludge. If we can supply the oil then people will use it."
