In the operation of smoking/burning type volume reduction treatment apparatus (1), referring to view (A), charcoal carbonized layer (T 2 ) is spread over powdery ceramic layer (T 1 ) in the state of having negative ion air fed through air supply inlet (H). Further, sawdust layer (T 3 ) is spread thereover, and thereafter treatment subject layer (V) is piled thereon. In a temporary burning region of the carbonized layer (T 2 ), the powdery ceramic layer (T 1 ) exerts not only heat storing action but also heat radiation action. Referring to viw (B), the interior of the sawdust layer (T 3 ) is altered into temporary carbonized layer (T 31 ) and temporary dried layer (T 32 ). As the temporary burning region slowly moves upward, an under side of the treatment subject layer (V) is altered into dried layer (V 1 ) and further, carbonized layer (V 2 ) shown in view (C) is formed. Thereafter, this carbonized layer (V 2 ) catches fire, so that burning region (V 3 ) is formed in layered form in the treatment subject layer (V). Thus, smoking/burning starts. Accordingly, there can be provided a method wherein a burning region is securely formed in the treatment subject within the apparatus (1).
