A method of agglomerating solid particulate waste material includes heating and fluidizing a bed of non-combustible granular material, the temperature being lower than the melting temperature of the granular material and the fluidization being accomplished by passing a gas through the granular material. A slurry containing the material to be agglomerated is introduced into the bed. The combustible material in the slurry is partially oxidized by means of heat generated by fuel combined with material in the slurry for drying and agglomerating said material and the dried and agglomerated material is removed from the bed. The apparatus includes a combustion chamber, a bed of non-combustible granular material in the chamber, circulating means for passing a gas through the bed, and heating means for heating and maintaining the bed at an elevated temperature. Introducing means is provided for introducing the solid particulate waste material into the bed in the form of a slurry, the waste material being dried and agglomerated through partial oxidization by means of heat generated by fuel combined with the waste material. Removal means is provided for removing the dried and agglomerated waste material from the combustion chamber.
