As an effective utilization of waste stillage which will be banned to dump into sea from the year of 2001, authors have studied and succeeded to make soseipaper by using waste stillage from shochu distillery.
This research is tried to compare the physical and mechanical properties of sosei paper produced by using sweet potato waste stillage (hereafter, SPWS), barley waste stillage (hereafter, BWS) and old newspaper, and to consider the weight and property of waste water after compressing samples (waste stillage + old newspaper). Further, this research is applied to the growth test of Chingensai in a pot made of sosei paper.
Following results were obtained;
1) Barley soseipaper was greater in density and less in strength than sweet potato soseipaper. 2) After compressing samples, in the case of the sample whose ratio ofold newspaper to waste stillage is 1%, more than 70 % of the CODCr, TOC, T-N components can be removed from waste water in the case of SPWS, and so can more than 45% of them in the case of BWS.3) In the growth test ofChingensaiin a pot made of soseipaper, the plant absorbed components in soseipaper, and the paper proved to be effective as a fertilizer.
