Our second stop took us to Harvest Power, a company whose vision is to find the highest and best use for the 500 million tons of organic material produced in North America each year. Currently, compostable organic material makes up the largest and heaviest portion of the overall waste stream in the U.S., according to the U.S. Environmental Protection Agency.
ZDNet, “Could food waste power our cities?” by Julie Mehta
In two giant airtight vats at Harvest Power’s Energy Garden in central Florida, quadrillions of microorganisms are feasting on orange peels, wilted lettuce, burnt bread crusts, and other food discarded by humans. In less than a month, these ravenous creatures consume waste that would have taken years to decompose in a landfill.
Better yet, they release immense amounts of gas — biogas, to be exact. This heady mix of roughly 60 pecent methane and 40 percent carbon dioxide is fed into generators to produce electricity to help power area businesses.
