Method and apparatus for treating wastes by gasification

A method for treating combustible matter by gasification, said method comprising:

• supplying said combustible matter into a reactor;
• gasifying said combustible matter in said reactor at a temperature ranging from 450 to 800° C. by contacting said combustible matter with a gasifying agent supplied to said reactor;
• introducing gas and char produced in said reactor into a high-temperature combustor;
• producing calorific gas in said high-temperature combustor by combusting said gas and said char at a temperature of at least 1300° C. by contacting said gas and said char with gas supplied to said high-temperature combustor;
• and
• producing methane from said calorific gas.
