The Pigsjin of Umbak
The Pigsjin of Umbak are the original creation by the Umbakians to manage waste and create natural gas fuel in their larger settlements. It has gradually led to a wider use of The Pigsjin in general in the Steel Realms, though it is much more prevalent in Umbak.
Its also used by extracting it from offal piles at large farms, towns and cities. The organized creation of The Pigsjin – offal pits, collection for and taxation/fines if NOT used has allowed beacons and Hearth Stations of Umbak to be warmed.
