Methane

Landfills produce a lot of methane gas, one of the main greenhouse gases contributing to global warming. In an effort to both reduce that impact and responsibly reuse the gas, some municipalities are converting it into energy.

We shouldn't be blaming biofuel production for rising food prices and environmental degradation while ignoring the immense harm of industrial meat production, writes Frances Cerra Whittelsey.

In an incredible recycling operation that reduces global warming, a waste hauler is building a facility to produce Liquefied Natural Gas from methane emitted from its California landfill to fuel its garbage trucks.
