<p>A plastics processing apparatus 10 has a hopper 12 for receiving a plastics material, a barrel 14 having one or more screws 16 disposed co-axially with the barrel 14, a breaker plate 18, disposed on a distal end of the barrel 14, having one or more output apertures, a heater 20 and a motor 24 for driving the, or each, screw 16. The heater 20 provides heated fluid to the hopper 12 and/or barrel 14. The heated fluid is heated from heat derived from the exhaust of the 24 motor. The motor 24 may be a steam motor driven by steam from a biogas fueled boiler. Solar heating may also be used to preheat a working fluid.</p> |
