Abstract: Method for decomposing thermally decomposable components such as organic compounds which are present in gases, whereby these gases are led through a heat exchange medium consisting of particles of a substance such as clay or aluminates which resist decomposing at the decomposition temperature of the decomposable of the decomposable components, and whereby these gases are heated in the heat exchange medium up to the decomposition temperature of the decomposable components.

Abstract: A thermal method for continuously processing waste having a calorific value and any degree of moisture, wherein waste is put in a flow of hot, heat-resistant, heat-exchanging material which is warmer than 100.degree. C. The heat exchanging material cools due to heat exchange, the waste dries and the non-evaporated waste components are heated. The cooled, heat-exchanging material is subsequently separated from the dried waste materials and the separated dried waste material is mixed with a percentage of the separated heat-exchanging material. The dried waste material and heat-exchanging material mixture is subsequently heated to pyrolyze waste material and heat the heat exchanging material in preparation for its subsequently use in the continuous process.
