Generate more than a charge for your slurry

PRODUCERS can now diversify into electricity generation with the launch of a new farm biogas system producing power from muck.

Electricity companies will be looking for new suppliers if they are to meet EU targets, says Weda director Malcom Taylor. "By 2011, more than 10% of their supplies must be from renewable resources.

"One solution is biogas, a 200-sow farrow-to-finish unit produces about 1m gal of slurry which can be converted into 366,500kW of electricity. This is worth up to £29,000, allowing the investment in the system to be recouped within eight years."

There are also other advantages with the system, including smell reduction, easier disposal of processed slurry and surplus heat for glasshouses.

The new system from Weda, Northants, launched at the Pig and Poultry Fair is supplied as a complete package with an insulated stainless steel fermenting tank and a generator which produces electricity. A system producing 366,500kW of electricity costs about £200,000.

Slurry can be converted into electricity which producers can sell.
