Previoiusly we told you that the city of San Antonio, Texas was converting human waste to natural gas.  Now we find out from the BBC that a plant in Lancashire, England is doing the same thing by converting human waste into biogas.

United Utilities is converting a by-product of waste water at its Blackburn plant into gas.

The company is using the method to generate about 15% of the power it uses in its operations…The power generated helps run the sewage treatment works next to the United Utilities plant.

The plant also exports highly nutritious fertilizer to agricultural land across east Lancashire for farmers free of charge.

The plant processes up to 168 megalitres daily. The biogas is produced when waste water sludge is broken down by microbes in a process known as anaerobic digestion.

United Utilities also uses anaerobic digestion technology to treat sewerage sludge and generate electricity at a number of  other treatment operations across northwest England.
