Answer:
This has some interesting History in it.
Peat moss was once pounded into a sort of brick; sometimes with a little coal, these bricks were put to dry, and used for fuel.
The “Historical” part is in the name. I won’t go into why, ‘cause I type so slow and it is “extra”, but the peat, or coal, being TRULY organic, (that is made from plants) and burned as fuel is called “carbonixation”.
Explanation: Sort of a “Carbon + Oxidation”; many things in Chemistry have strange names that seem at first to make no sense; like “essence of Hartshorn”, is Ammonia (or ammonium hydroxide). A Hart is/was a type of deer in England and that area, and amines in the horn, when distilled, would yield Ammonia, “The Essence of Hartshorn”. Even the term “aromatic” has a long History, as do many compounds and nomenclature.
I hope that will do it.
