What if, instead of going in the trash or, worse, in any discreet corner of the street, the bags of dog excrement were used to power the streetlights that illuminate our cities? Tired of how the second option repeated itself around his home, Brian Harper, 66, has just activated the first streetlight in England that runs on dog feces from which methane is obtained to fuel the system.
After years of working on the idea, this neighbor from Malvern Hills, Worcestershire, has managed to get the unique design that already lights up the exterior of his house to virtually go around the world. Innovation is not only achieved, but It is a waste of facilities so that owners of dogs that roam the area are encouraged to participate in this initiative. Getting ten people to do this and drop a paper bag with their pet’s droppings into the Harper-designed system translates, directly, into two hours of nighttime lighting.
All it takes is for the neighbors to feed their dog’s droppings into the system (for which Harper even activated a paper bag dispenser), then crank a crank a few times. There the work of the neighbors ends and that of the team begins. And it is that, with this gesture, what is achieved is that stool passes through a biodigester chamber in which microorganisms break down feces.
In a few days, this process produces the methane that powers this lamp post, which is, in addition to being a pioneer of sustainability, intelligent. Proof of this is that the lamp itself detects the absence of light to, at that precise moment, go to the biogas to illuminate a street which, overnight, was put on the national and international map.
After fashioning this lamppost, for which he received support from the Malvern Hills Area of Outstanding Natural Beauty (AONB), this Briton will analyze how it works to see if it is necessary to implement adjustments that improve the system. After this period, your most immediate goal is to be able to extend this solution to other areas of your locality. These street lights “They spark people’s imaginations and show them that their dog’s droppings are valuable”Harper assures the local newspaper Malvern Gazette, in which he expresses another of his goals. “That local authorities and other bodies across the UK are interested”. With millions of tons of dog excrement, the raw material to light up the cities of this territory and any other, there is certainly no shortage.
