Abstract
Residues such as wood chips or coffee dregs have been disposed of industrial waste.However owing to revision of the relevant laws, it has become necessary that more than 20% of the waste is recycled. In this study, wood chips and coffee dregs were baked in a self-burning rotary kiln to produce porous carbonized materials. We examind five types of specimens, i.e., wood chips baked with and without clay minerals, coffee dregs baked with and without clay minerals and conventional carbon made of coconut palm. Deodorization effect concerning gas emitted from garbage, river water, industrial wastes and decolorization concerning river water were evaluated. The carbonized materials made of wood chips or coffee dregs baked without clay minerals indicated good performance.
