Methane from sewage to be used to generate electricity at Pyewipe
POWER from your poo will be used to help save the planet.
Thanks to a £28 million investment by Anglian Water, methane from sewage from North East Lincolnshire and northern Lincolnshire will be turned into electricity to help process the waste more efficiently.
With most of Lincolnshire being flat terrain, the firm is forced to pump large quantities of waste to sewage works, which require increasing amounts of electricity.
Bosses said the new system at Pyewipe will make the plant self-sufficient and use recycled gas to reduce fossil fuels.

Once complete, the electricity generated at Pyewipe (9 Gwhs) will be equivalent to powering 2,150 homes for a year.
By 2015, the nine sludge treatment centres across the Anglian Water region will produce enough electricity (86.8 Gwhs) to power almost 22,000 homes for a year.
As part of the process to help generate their own sustainable energy, two huge engines were installed at Anglian Water's Pyewipe sewage treatment works yesterday and capacity is set to double from 9,000 of dry solids to 17,000 tonnes.
They are due to be plugged in and start generating power by the start of next year, with all surplus electricity to be exported to the national grid.
The Pyewipe works improvement scheme is one of nine within the Anglian Water region, which stretches from the Thames to the Humber.
Catchment manager for Lincolnshire Peter Joyce said: "These engines will be used to convert the gas produced by treating sewage sludge into electricity to power the works and into heat, which is recycled back into the treatment process.
"Any surplus electricity is sent to the grid. At Pyewipe, one of the engines should be able to power the whole works while the other generates power for the grid."
Not only will the more efficient system help to reduce Anglian's carbon footprint, but it will also increase the amount of sludge being treated at Pyewipe and amount of treated waste that can be sold as fertiliser on crop growing fields.
Mr Joyce said the pellets, which have bacteria removed, were a prime substitute for nitrate and phosphate fertiliser.
He said: "We will be able to put it on more fields and use it in agriculture, giving it to more farmers."
The pellets are also used on golf courses and to generate more heat in furnaces, the spokesman said.
As reported, Anglian Water has increased householders' bills by 3.5 per cent this year. The firm is also seeking the views of its 6.1 million customers about its next five year plan starting in 2015.
The consultation will determine whether more is spent on reservoirs in the area or in stemming leaks, or more investment in recycling.
