A method for roasting a load of plant biomass, includes the following stages: generation of a treatment gas stream by a thermal generating apparatus, the treatment gas stream being an inert gas consisting essentially of CO2; generation of a bed of material at high temperature, called the thermal base; treatment of the load of biomass with the treatment gas stream, the treatment gas stream being laden with gaseous components including a water steam and volatile organic compounds originating from the load of biomass during the treatment; and recycling of at least a portion of the water steam by passing at least a portion of the laden gas stream through the thermal base.
