The need for proper disposal of effluents from the dairy industry is causing some strong interest in the evaluation of alternative treatment systems. Anaerobic digestion is a preferred candidate in many applications since it can be accompanied by energy recovery and also the pollution reduction needed consumes no oxygen for a high percentage biological oxygen demand/chemical oxygen demand removal. Some aerobic polishing will be required for river quality discharge. The economics of anaerobic digestion alternatives point to a return on capital expenditure–an unusual feature of a waste treatment process. The technology has been shown to be reliable and effective in full‐scale operation; the economics which have been demonstrated in several large scale operations need to be applied on a wider basis within the dairy industry .
