It’s only the size of a waste bin, but this mini power plant has the potential to turn household waste into ready-to-use fuel.
The Home Energy Recovery Unit (HERU) was developed by researchers at the Brunel University in London, England. Using a process called pyrolysis, HERU turns household waste into energy-rich liquid, char, or synthesized gas fuel. The unit connects to the water and drainage system of a house and uses the fuel to heat water. The resulting gas is then cleaned before being vented into the atmosphere, creating a sustainable renewable energy source.
Not only can HERU eliminate waste, it can help the homeowner cut energy bills. The unit uses just 1 kWh of power for every 2.5 kWh of energy it produces. According to the inventors, this could save families up to 15% in fuel.
What makes this tech truly green is its potential to address two pressing environmental problems at once: waste management and fuel production.
“Waste management is one of the most crucial challenges developed countries face,” said co-inventor, Dr. Hassam Jouhara. “Rising fuel costs leave so many households with the difficult decision of whether to eat or to heat their home and countries worldwide are being urged to cut carbon consumption. The vision is to solve this global problem and slash energy bills while producing energy for heating from waste that is otherwise a burden on local authorities and households.”
Installing a waste-powered generator would cut down on landfill waste and reduce reliance on other energy sources. The creators, who are based in the U.K., believe it could cut the U.K.’s carbon footprint for waste disposal by over 70%. While the tech hasn’t hit the consumer market, HERU could be a hero for green energy.
