1. A method for providing raw material for an industrial process, in particular for steel production, comprising:
torrefying a torrefaction material, which comprises biomass, in a reactor by thermochemically treating the torrefaction material at a temperature of 200° C. to 600° C., to obtain bio coal,
extracting the bio coal from the reactor at a first temperature of up to 600° C.,
providing bulk material at a second temperature between 0° C. and 100° C., mixing bio coal with a bulk material, thereby cooling down the bio coal with the bulk material and
obtaining a mixture of bulk material and bio coal at a third temperature, below the self-ignition temperature of the mixture, and
using the mixture to provide the raw material for the industrial process.
