A Bio-Coal is a fuel that is produced through contemporary processes from biomass rather than a fuel produced by the very slow geological processes involved in the formation of fossil fuels such as oil Since biomass technically can be used as a fuel directly eg wood logs some people use the terms biomass and bio-fuel interchangeably More often than not however the word biomass simply denotes the biological raw material the fuel is made of or some form of thermallychemically altered solid end product like torrefied pellets or briquettes If the biomass used in the production of BioCoal can regrow quickly the fuel is generally considered to be a form of renewable energy BioCoal can be produced from waste plants any plant crops leaves or from agricultural commercial domestic andor industrial wastes if the waste has a biological origin
