As the Obama administration weans the U.S. off polluting fuels blamed for global warming, energy companies have been sending more of America’s unwanted energy leftovers to other parts of the world where they could create even more pollution. Here are five things to know about the issue:
Worldwide demand for coal, perhaps fueled by U.S. exports, rose 3 percent in 2013. Experts predict it will continue to grow.
Chad Hancock, a technician with Engineering and Environmental Consultants Inc., uses a device to monitor the amount, concentration, temperature and percentage of methane gases from a well at the Los Reales Landfill. Wells are connected to vertical perforated piping that runs throughout the l…
The Arizona Department of Environmental Quality is seeking federal permits to convert landfills like Los Reales to bioreactors. The addition of water to the landfill is expected to accelerate the rate of waste degradation, creating more methane.
More liquids - and, critics fear, some illegal hazardous wastes - could be coming to Arizona's 39 garbage landfills if a new technology for treating landfill liquids wins federal approval.
This is the existing methane-capture system and part of the Los Reales Landfill gas-to-energy project. Bioreactor opponents are worried about additional water use and the threat of groundwater contamination.
