This research paper focuses on the characterization of molasses spent wash collected from the local distillery in Baramati. Molasses spent wash is a by- product of the alcohol production process, and it is known to contain high levels of organic matter and nutrients. However, the improper disposal of this waste can lead to environmental pollution and health hazards. The study involved the collection of samples from a local distillery in Baramati, District Pune, India. The samples were analyzed for physicochemical parameters such as pH, electrical conductivity, total solids, total dissolved solids, total suspended solids, chemical oxygen demand, and biochemical oxygen demand. The nutrient content of the samples was also analyzed for total nitrogen, total phosphorus, and potassium. The results indicated that the pH of the samples ranged from 4.5 to 5.5, and the electrical conductivity ranged from 1.2 to 2.5 dS/m. The total dissolved solids and total suspended solids were high in all the samples, with values ranging from 12,600 to 14,700 mg/L, and 2,100 to 6,500 mg/L, respectively. The chemical oxygen demand and biochemical oxygen demand values were also found to be high, indicating the presence of high organic matter content in the samples. The nutrient content of the samples was found to be high, with total nitrogen, total phosphorus, and potassium levels ranging from 4,500 to 7,700 mg/L, 660 to 1,400 mg/L, and 9,500 to 18,600 mg/L, respectively. The results of this study provide important insights into the physicochemical and nutrient composition of molasses spent wash collected from an alcohol distillery in India. The high organic matter and nutrient content of the waste can be harnessed for beneficial uses such as the production of biogas and organic fertilizers. However, proper treatment and disposal measures need to be implemented to prevent environmental pollution and health hazards.
