The depleting fossil fuels and anthropogenic climate change require involvement of renewable energy resources, including animal wastes. One of the effective, although less studied, ways of the cattle manure transformation to a convenient energy source is its microwave pyrolysis (MWP) into a combustible gas. The MWP of cattle manure was experimentally studied, using differential thermal analysis, scanning electron microscopy, BET surface measurement, and high-speed video recording. Spark discharges between inorganic centers with metallic or semiconductor properties in the MWP-treated manure were found responsible for the MW-radiation impact. It was experimentally shown that on course of thermal destruction, the absorption of microwave radiation by manure increases almost two times probably due to a change in the composition of carbon-containing compounds and the release of gases, tar vapors, and pyrogenic water. The MWP treatment provides fast and uniform heating of manure with its more complete volatilization, leaving only 34.5% wt. of carbonaceous residue compared to 42.7% in thermal pyrolysis. The MWP gas is of relatively high calorific value (21.08 MJ m−3) at low content of ballast gases, thus providing environmentally friendly manure transformation with a lesser greenhouse effect.
