Dairy Herd Could Power a Whole Village

UK - An organic farmer believes Wales can become a world leader in using cow dung to produce green electricity. Richard Tomlinson says his 600-strong dairy herd generates enough dung to power the entire village of Holt, close to his Lower Parks Farm.

The method generates power after dung is mixed with food waste in a generator and is already popular on parts of the Continent.

Mr Tomlinson, who hopes to begin using the method soon, held a meeting last night with locals in Holt, which has 500 homes, to allay fears over unwanted smells.

The power is generated by burning methane gas produced by the dung and the food waste when they decompose.

The technique is known as anaerobic digestion because the decomposition process is speeded up by placing the dung and food in an oxygen-free tank.

All waste left after the process can be used as fertiliser.

Mr Tomlinson, who describes himself as a committed environmentalist, says the generator would help the village near Wrexham become carbon-neutral.
