landfills

A leading source of U.S. climate pollution could be curbed with more gas-collection systems and better emissions monitoring, environmental advocates say.

Miami-Dade County Commissioner Rene Garcia tells WLRN that waste management is not always top of mind for a lot of people. But the Covanta energy plant fire in Doral has pushed for a rethink of South Florida's relationship with trash — how much waste people produce and where to put our garbage for the long haul.

A study builds on research that shows landfills are the third-largest source of methane emissions globally, after oil and gas systems and agriculture.

Julie Bargmann, the first recipient of the Oberlander International Landscape Architecture Prize, redesigns waste dumps, landfills, Superfund sites — places she calls "the gnarliest."

Landfills are among the nation's largest sources of methane, a greenhouse gas far more potent than carbon dioxide. But accurately measuring methane is a major challenge to reducing it.
