Landfills are all the rage these days. Capturing methane emissions from large trash sites has long been considered a solid energy-saving idea, but now a new trend sees capped landfills contributing to renewable goals in yet another way: solar power.
One site in Canton, Massachusetts, along with Southern Sky Renewable Energy, will install 5.6 megawatts of solar photovoltaic panels over the top of a capped landfill. They say it will generate as much as $70 million in combined savings and revenue over the next 25 years. When complete, it will be the largest solar installation in New England.
Jeffrey Osuch, executive secretary of another town in New Jersey following a similar plan, told the AP why this is an appealing idea:
"Capped landfills have turned out to be a prime location for solar panels since they tend to be raised, can't be built on and have to be clear of trees to protect the integrity of the lining."
More generally, there is a glut of ideas floating around based on how better to use waste, landfills, and the like. Last year we covered here how Spain could get a full seven percent of its power from waste materials, and that British Airways will soon start to make use of a waste-to-fuel plant. And if none of those work, you can always turn your Staten Island landfill into a giant park.
