Identification of an Appropriate Alternative Waste Technology for Energy Recovery from Waste through Multi-Criteria Analysis

Waste management is now a global concern due to its high environmental impact on climate change. Becaus e of generating huge amount of waste through our daily activities, managing waste in an efficient way has become more important than eve r. Alternative Waste Technology (AWT), a new category of waste tre atm nt technology has been developed for energy recovery i n ecent years to address this issue. AWT describes a technology that redirects waste away from landfill, recovers more useable resources from the waste flow and reduces the impact on the surroundings. Au stralia is one of the largest producers of waste per-capita. A number of AWTs are using in Australia to produce energy from waste. Pr sently, it is vital to identify an appropriate AWT to establish a susta inable waste management system in Australia. Identification of a n appropriate AWT through Multi-criteria analysis (MCA) of four A WTs by using five key decision making criteria is presented and discussed in this paper.
