Capturing Cow Farts

While carbon dioxide, the most abundant greenhouse gas, can be captured using a variety of techniques, methane capture has proved elusive. Damned cows!

But recently it has been discovered that various forms of zeolites, commonly used in water purification and other industrial processes, appear well-suited for the task.

While in an early stage, the technology is promising given that concern over methane emissions at hydraulic fracturing sites and the potential for large-scale releases of methane as the Arctic permafrost thaws.
