Lignite, also known as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a low carbon content of around 25–35%, and high Ash and Volatile Matter Content. It is considered the lowest rank of coal due to its relatively low heat content. Lignite has a low heating value and is mainly used in electricity generation.
