　 　The sludge produced as an industrial waste in waste paper recycling is called waste cellulose sludge. In this study, we carried out the basic research necessary to make a seedling pot which utilizes the waste cellulose sludge as a raw material.　In order to observe the presence of any negative effects on the plant when the waste cellulose sludge is mixed with soil, we prepared the field and the petri dish and observed the growth conditions of these plants (white radish sprouts and weeds). The results showed no negative impact on the plants grown in the soil in which a low ratio of the waste cellulose sludge was mixed.　As a method of producing the seedling pot which used waste cellulose sludge, we made a form that had a thickness of about 2~3 cm without breaking and then dried it.　In this way, we could make it into the form of a container.
