A treatment of the wasted flower plants used for the waste water treatment process by the indoor drying and pressing method was studied for their effective reuse as columnar solid fuel. Three kinds of wasted flower plants were processed for making samples by indoor drying method for about two months. The samples which were chop plants about 10cm long, half powdery ones and powdery ones were made into the columnar solid fuels under 1-5 t·cm-2 pressure.According to the drops strength test for the solid fuels, it was investigated that they lost their physical strength rapidly in proportion to the elaspsed time. The solid fuel made of powdery processed plants particularly lost its strength most lapidly.In the case of solid fuels made of chops, when they were pressed by the method that the trunk and the branches filled into the presss vessel in the same direction against the presss one, their physical strength were maintained for a long time. Furthermore, the form of solid fuels processed by this method looked like keeping their original one for a relatively long term. It was found that their combustible efficiency was exellent because the combustible calorie of the wasted plants ranged from 3,600 cal·g-1 to 3,800 cal·g<sip>-1.
