From garbage to gigawatts
Beginning next summer, landfill-bound garbage trucks in Massachusetts might smell a little less putrid than usual, thanks to a new regulation that would prohibit any generator of more than a ton of food scraps per week from hauling those scraps to the dump. As the state finally gets serious about diverting food waste, it expects to be sending much of it elsewhere: to hungry people, animal-feed producers, commercial composters, and the high-tech contraptions known as anaerobic digesters, which convert waste to energy and fertilizer.
With the passage of the new regulation, Massachusetts will join its neighbors Vermont and Connecticut in requiring that large amounts of organic waste go somewhere other than landfills. (New York City mayor Michael Bloomberg has expressed his wish to enact a similar requirement before he leaves office at the beginning of next year.) Should these regulations have their intended effect, the Northeast will likely see a major surge in the technology of anaerobic digestion (AD).
