This study examined with carbonized sludge produced carbonating sewage sludge for using cutting media of chrysanthemum. Sewage sludge were carbonized at 700℃ during 20min. After carbonization, carbonized sludge were cooled in air. Analysis of heavy metal were determined below permition. Experiment for effect of carbonized sludge on chrysanthemum growth were carried out. Growth of subastral in cutting media, plant height and number of leaves, were better mixture of carbonized sludge than comparison. Two cases of cutting media using only carbonized sludge and carbonized sludge+perlite(1:1) were not combined. On the other hand, carbonized sludge+sphagnum peatmoss(1:1) were combined likely comparison.
