<p>A process for the recovery of energy values from waste biodegradable material comprises passing comminuted waste material through a pyrolysis reaction chamber (13) and cooling the gaseous pyrolysis reaction product, in which the pyrolysis (24) and cooling chambers (14) are adjoining and the waste material is advanced through the pyrolysis chamber by advancement means comprising rotary drive shaft means (25) sealingly journalled through the wall of the cooling chamber remote from the pyrolysis chamber. The drive shaft gland (28) is therefore removed from direct exposure to the heat of the pyrolysis reaction and higher pyrolysis temperatures can therefore be tolerated, with a greater ability to treat biologically-active waste or other hazardous materials and a significantly faster processing time being achieved.</p> |
