Introduction
 
Technology has improved living standards of human beings on one hand but it has also increased the demand of energy on the other hand. Limited natural resources are being exploited to fulfil this increasing energy demand, which has also resulted in rapid environmental degradation. However, sustainability must be considered for social and economic development of the world while coping with growing energy insecurity. Use of renewable energy resources could be helpful to solve all these problems. Renewable energy is the energy obtained from natural sources which are replenished naturally. Anaerobic biotechnology is a cost effective and sustainable approach for production of bio-energy, which is a type of renewable energy. Use of anaerobic technology for conversion of available organic feedstocks (especially organic wastewater and solid waste) not only produces bio-energy but also meets environmental objectives. It involves various fields of engineering and sciences such as agriculture, biology, chemical engineering and environmental engineering as well as renewable energy technology. Thus the main focus of this research group is to explore various types of locally available organic wastes for production of renewable energy (i.e. biogas) through anaerobic digestion process, which can reduce emissions to environment and produce digestate, a soil amendment.
