Tiny red crystals dramatically increase biogas production

(University of New South Wales) UNSW Australia-led researchers have discovered a way to produce a tenfold increase in the amount of methane gas emitted by naturally occurring microbes living in coal seams and on food waste. The innovation could benefit the environment by extending the lifespan of coal seam gas wells, as well as improving the economics of using woody crops and left-over food as commercial sources of biogas.
