The invention provides apparatus and method of pyrolysing feedstock to produce char. A feedstock advancing mechanism in a lower portion of a substantially sealed reaction chamber advances the feedstock laterally along the lower portion as it pyrolyses in its progression from the proximal end to the distal end. Char is discharged from the distal end of the reaction chamber. A control system controls at least the flow rate of oxygen containing gas entering the chamber via the inlet port in response to the temperature measurements in the reaction chamber so that the temperature measurements are appropriate for the production of char from the feedstock and so that a zone of volatile gas combustion is established in the headspace, involving essentially complete consumption of all incoming free oxygen in the headspace without contacting the feedstock.
