Biorefinery platforms – Biochar / Charcoal
Versión en Español BIOREFINERY PLATFORMS Concept - Biochar is a solid carbon-rich material produced by thermal decomposition of organic material at relatively low temperatures in the absence or limited supply of oxygen. - It is the main product obtained in biomass carbonisation (slow pyrolysis) or a co-product in biomass pyrolysis and gasification. - During these processes, carbon is not released into the air as CO2. Instead, it is stably bound in the biochar and removed from the atmosphere. When the biochar is permanently incorporated into carbon sinks (soil, asphalt…), its production can be considered as a Negative Emission Technology (NET). - Some voices claim that the word “biochar” should be only used for agricultural applications. According to them, the voice “charcoal” is the appropriate to cover all the vast range of qualities and grades for carbonised biomass. - Conditions like feedstock type and particle size, reactor type, residence time, heating rate… affect the physica...
