Engineering360: "What is renewable natural gas?"

If the methane is going to be naturally produced as a consequence of having the organic waste, it makes all the sense in the world to capture and use it. It's silly to argue that not doing so avoids the problem of free methane in the atmosphere.

The wastewater treatment plant in my community captures methane produced and uses it for process heating and facility heat in the winter. Excess methane produced in the summer is stored for use in the winter or burned in a nearby natural gas-powered electrical generating plant. Everybody wins.

Oh, and this is just another loop in the natural carbon cycle. The real issue is not whether carbon dioxide from human-extracted fuel belongs in the environment (it was in the ecosystem before it got locked into sedimentary rock formations; that's why we call it fossil fuel), but whether there is sufficient photosynthetic activity to take it up again. We should be working on increasing plant growth instead of paving over farmland with wind turbine foundations and solar panels.
