carbonization or slow pyrolysis
Carbonization and roasting are partial pyrolysis of the biomass carried out under atmospheric pressure in a narrow temperature range between 200 and 300 ° C, and in an inert environment (absence of oxygen).
The carbonization process can be used to convert several types of raw materials (wood waste, biomass, organic waste, etc.) into a solid product with a higher energy content and which can be post-processed for appropriate and effective handling. subsequent processes (e.g. briquetting or pelleting for solid fuel production).
