Claim Text:
1. A batch processing method of pyrolysing and/or gasifying organically coated waste and organic materials, the method comprising: in a first mode of operation heating the material in a processing chamber, by recirculating hot gas therethrough, to pyrolyse and/or gasify it to produce syngas and soot and a residual material; and in a second mode of operation increasing the oxygen content of the recirculating hot gas such that the oxygen reacts with the soot to form carbon monoxide; and in the second mode of operation: monitoring one or more of the calorific value of the gas, the hydrogen content of the gas, the carbon monoxide content, and the temperature of the gas; and if one or more of the calorific value, the hydrogen content, and the carbon monoxide content of the gas is below a predetermined threshold, and/or if the temperature of the gas remains substantially constant; ending the process.
