Abstract

Anaerobic digestion is a process to stabilize the organic matter in the waste and accordingly it finds an important place in the area of biological means of waste management. During this course, renewable energy in the form of biogas is generated thus making this process remunerative. Innovation of UASB process and other advancements in this area for the past three decades made this process economically attractive for the treatment of high strength organic wastewaters and therefore, this technology penetrated rapidly in those industrial segments. Despite this, scaling up of technology has many bottlenecks which need to be understood thoroughly in order to tailor made the process for new category of wastewaters. Application of this technology for the treatment of solid waste is not at the required pace due to variety of reasons, especially in developing countries like India, even though the technology became mature in European countries and is being applied widely. Payback period of anaerobic systems for solid waste is not commercially attractive like anaerobic wastewater plants which could be possibly one of the main causes for sluggish take off. In order to expedite the commercialization of solid waste treatment plants based on anaerobic digestion technology, apart from indigenizing the high rate biomethanation technologies to reduce the cost of technology transfer, necessity of implementing environmentally benign, less energy consuming solid waste treatment technologies like anaerobic digestion needs to be advocated aggressively. The presentation addresses present status and future perspectives of anaerobic digestion technology with practical examples.
