Synthetic gas

These gasses are combustible, and are often stored to be burned as a fuel source.

For the most part, the ammount of synthetic gas produced in a waste to energy facility is only enough to keep the plant operating.

Coal gasification processes[1] (http://www.heritageresearch.com/manufactured_gas_C.htm) (e.g., the water gas[?] process) are reasonably efficient and were used for many years to manufacture illuminating gas[?] for gas lighting[?], before electric lighting became widely available.

Syngas is a short form for synthetic gas.
