Method for processing waste with a calorific value with any degree of humidity whatsoever by means of a thermal treatment, whereby the waste is put in a flow of a hot, heat-resistant, heat-exchanging material which is warmer than 100 ~C, whereby the material cools off due to heat exchange, the waste dries and the non-evaporated waste components are heated, whereby the cooled, heatexchanging material is subsequently separated from the dried components, at least a part of the separated dried waste components is joined together with at least a part of the separated heat-exchanging material and whereby these waste components are subsequently subjected to pyrolysis, whereby the heatexchanging material is heated before being used to dry the waste, characterized in that a granulated material is used as heat-exchanging material, in that the dried waste components which are separated from the granulated material are mixed with only a part of the separated, cooled granulated material and this mixture is subjected to the pyrolysis and in that the rest of the separated, cooled granulated material is mixed directly with granulated material heated by the pyrolysis and in that the thus obtained mixture is used to dry the fresh waste.
