Renewable, Cost-effective, Carbon negative

Page last modified

Torrefaction is a heating process of biomass in a non-oxidizing atmosphere, necessary to improve raw biomass materials. Torrefied biomass properties include a lower moisture percentage, a higher energy density and heating value. Torrefied material is easier to grind and to pelletize. These properties all translate into a sustainable and economic higher value.

During this torrefaction process, combustible emission gasses are released. The Yilkins torrefaction technology brings these combustible emission gasses back into the main process to provide the required process heat, making Yilkins torrefaction a very economic technology.
