Bio charcoal (Biochar) is a fuel of high calorific value that is produced by the process of pyrolysis.
The process of carbonization results in the carbon present in the biomass being concentrated to the maximum. In contrary to the original wood, which is made up of no more than 50% carbon, charcoal contains between 60 and 90% and its water content is very low, which means charcoal is an efficient fuel.
What uses of charcoal?
Bio charcoal is mostly used as a domestic fuel in developing countries, to cook food, but also as heating.
It can also be used in the metallurgic industry (reducing agent for iron ore) or as a filter (active carbon filters).
