Milk processing consumes a large amount of water and generates 6–10 liters of effluent per liter of milk processed. An effluent volume is approximately four times the volume of processed milk. Since the pollutants generated by industry are great losses of production, improvements in production efficiency are recommended to reduce pollutant loads. In this research a series of experimental studies were conducted with regard to bioconversion of organic fraction of municipal solid waste along with dairy waste water at different C/N ratios. About 50 kg of shredded waste containing dairy waste water, saw dust, and organic fraction of municipal solid waste was placed in static piles of different proportions and 500 ml of effective micro-organisms was added to them. The variation in physical and chemical parameters was monitored throughout the process. Results indicate that co composting of dairy waste water with municipal solid waste produces compost that is more stable and homogenous and can be effectively used as soil conditioner.DOI:
