Recent study finds ‘garbage lasagnas’ forming in open landfills across US release staggering amount of air pollution: ‘Decades of trash that’s sitting under the landfill’<\/a><\/h3>\n

Researchers discovered that over half had sizable methane plumes, which sometimes lasted for months or years.<\/strong><\/p>\n<\/div>\n<\/header>\n

Landfills across America are releasing far more\u00a0methane<\/a>, a potent planet-warming gas, than we previously thought.<\/p>\n

A study<\/a>\u00a0published in the journal Science found that our nation’s dumps are releasing almost three times more\u00a0methane<\/a>\u00a0than estimates from the Environmental Protection Agency indicate. It’s a discovery that could have major implications for our climate and our communities.<\/p>\n

What’s happening?<\/strong><\/p>\n

By flying planes over roughly 20% of the nation’s 1,200 large, open landfills, researchers discovered that over half had sizable\u00a0methane<\/a>\u00a0plumes, which sometimes lasted for months or years.<\/p>\n

This suggests that something has gone awry at these sites, such as big leaks of trapped\u00a0methane<\/a>\u00a0from layers of long-buried, decomposing trash.<\/p>\n

“You can sometimes get decades of trash that’s sitting under the landfill,” said study lead Daniel H. Cusworth, a climate scientist at the University of Arizona. “We call it a garbage lasagna.”<\/p>\n

Why are landfill emissions concerning?<\/strong><\/p>\n

When our vegetable scraps and old appliances end up buried in landfills, they decompose without oxygen,\u00a0releasing methane<\/a>. Over a 20-year period,\u00a0methane<\/a>‘s warming effect is a whopping 80 times more powerful than carbon dioxide,\u00a0according to<\/a> Stanford University’s Doerr School of Sustainability.<\/p>\n

The EPA already considers landfills the\u00a0third-largest source<\/a>\u00a0of human-caused methane pollution in the United States, equal to the yearly emissions of 23 million cars. But if landfills are emitting nearly triple previous estimates, the threat to our communities and climate is far greater than we realized.<\/p>\n
