uk's first street lamp to be powered by dog waste deposited by walkers proves a success in worcestershire - solar street lamp

Britain is now home to a dog shortage.
Electric street lamps that use dog deposits to generate electricity.
After a walk in Malvin Hill, walkers can put the dog's stool in the washing machine.
Like a device attached to a lamp.
It is then broken down by microorganisms to produce methane for farmers for light and fertilizer.
The creator claims that in this anaerobic condition, ten bags of poo can provide two hours of energy for the light, and can end the plump little bag of littering roadside garbage.
Scroll down to view video obrian Harper, who came up with the idea of this machine three years ago, with funding from the Malvern area with outstanding natural beauty, creating innovative light near Malvern Mountain, Worcester.
Harper, from transition Malvin Hills, a community environment organization, told the Guardian that the gas light captured people's imagination and showed them the value of dog dung.
As a result, we got [poo]
From the ground to the container, something useful is produced.
The dog walker must put a bag of their feces on a small machine attached to the lamp post and turn the handle.
When it is heated and mixed in an anaerobic bacteria, the feces release biological methane and generate electricity to power the light.
The concept of using feces is not new --
Since the Neolithic Age, humans have been using animal feces as fuel.
In Western developed countries, plants that extract heat and electricity from animal feces and human sewage are very common.
However, the supply of cheap fossil fuels makes it impossible for this potentially valuable resource to be fully utilized.
More and more people around the world are beginning to realize the potential use of such largely untapped resources.
In Ontario, pets were asked to put their feces in a concrete storage room.
These wastes are mixed with other forms of organic waste and broken down in large central factories.
The resulting methane is used to generate electricity and fertilizer is sold to farmers.
Experts believe the plan
Already in 18-month trial -
Enough power can be generated to power 13 families.
In 2014, Britain's first bus driven by human garbage was taken to the street. The 40-seater 'Bio-
Buses are fueled by methane gas, which is produced at a processing plant in the southwest to treat sewage and food waste.
And a tank of gas-
Typical annual waste production using five people-
Enough to travel 190 miles for the vehicle (305km).
The gas was produced by the Wessex sewage treatment plant operated by energy company GENeco.
It also became the first to start delivering the gas produced by human waste directly to about 5,000-
The State Grid provides 6,000 housing units.
The waste plant in Bristol Avonmouth processes 75 million cubic meters of sewage waste and 35,000 tons of food waste per year.
Using anaerobic digestion-
The process of using bacteria to decompose substances without oxygen
The plant can produce 17 million tons of bio-methane per year.
"Our facility is no longer a traditional sewage treatment project, but a factory that receives inputs including sewage and food waste and converts it into gas and nitrogen that includes for cooking or transportationand phosphate-
Mohammed Sadik, managing director of GENeco, told the Guardian: "rich fertilizer . ".
People talk about the circular economy, but what we are doing is putting that vision into practice, he said.
