Some Yeast


Yeast is an intermediary between sugar and sludge during the ethanol production process (sugar > yeast > sludge > ethanol crystals ).  If fermented with a plant product (sapling, leaves, sugarcane, etc.) it will produce sludge. It is also a necessary component of organic waste recycling using a composter.

Rotarycraft Handbook DescriptionEdit

"Yeast is cultivated in the fermenter by adding sugar and water to dirt. It grows best at temperatures between 20 and 40 degrees, peaking at 25 degrees. Outside this range, it will grow slowly or not at all. Be careful - at temperatures above 60C, yeast will die. Ethanol sludge is made from adding yeast to plant matter and water. It is created most rapidly at around 35C."
