In view of public demand for cleaner sludge discharged from factories for environmental protection, examinations were made on the pulp sludge dumped in K point of Fuji city, where there are many paper manufacturing factories, four times during June, 1973,to June, 1974. A large quantity of cyanide compounds was found in part of the sludge, and the D factory, which had dumped the said sludge, was examined in July, 1974. It was thereby found that the pulp material made from old newspapers and magazines, for manufacture of cardboard, contained a large amount of cyanide compounds which had been used for taking the ink off the paper. These cyanide compounds became concentrated in the pulp sludge through the process of de-inking, aggregation, and sedimentation.
