Biomass (Forestry)

Biomass is a liquid fuel introduced by Forestry that produces 5 Minecraft Joules per tick (MJ/t) for 10,000 ticks when consumed in a Biogas Engine. Biomass is produced by fermenting saplings and other organic materials inside a Fermenter.

Biomass is an important stepping stone in the creation of Ethanol, and is very similar to BuildCraft's Oil. However, Biomass is an easily renewable resource, while Oil requires complicated setups (often involving bees) to be renewable.
