Dog poo is powering a street lamp which is illuminating one of the UK’s most stunning beauty spots.
Dog walkers on the Malvern Hills, Worcestershire, deposit their pet’s poo in an anaerobic digester which converts it into methane to fuel the lamp.

The lamp needs 10 bags of faeces to provide two hours of light.
Inventor Brian Harper installed the lamp outside his home after seeing a similar contraption being used in Boston, America.
He said: ‘I looked and I thought this is a crazy waste. There must be a way of trying to give dog poo a value so people would do something sensible with it.’
The poo gets put in a bio-digester where it gets broken down by microbes, and then over two days it is converted into bio-gas, which is 60% methane and 40% carbon dioxide.

The Malvern Hills Area of Outstanding Natural Beauty funded the project and Brian told the BBC that dog mess on the hills has been reduced.
He said: ‘The public have a very sensible place to put it. They aren’t carrying it away, they can see dog poo is very useful and the light helps them if they’re coming down of the hill later in the evening.’
