Abstracts: Distillery spent wash is the unwanted residual liquid waste generated during alcohol production and pollution caused by it is one of the most critical environmental issue. Despite standards imposed on effluent quality, untreated or partially treated effluent very often finds access to watercourses. The distillery wastewater with its characteristic unpleasant odour poses a serious threat to the water quality in several regions around the globe. The ever-increasing generation of distillery spent wash on the one hand and stringent legislative regulations of its disposal on the other has stimulated the need for developing new technologies to process this effluent efficiently and economically. An emerging field in distillery waste management is exploiting its nutritive potential for production of various high value compounds. The attempt here is made to study the important characteristics of spent wash such as pH, EC, Phosphorus, Organic Carbon, Micro Nutrients, etc. on soil samples. The samples are tested every Saturday in the lab of Sayan sugar factory. Results obtained from collected samples are analyzed and its impact on soil is investigated. Hence whether the spent wash can be used as a liquid fertilizer will further be suggested.
