Energy from waste has been identified as a source of green energy and an effective method to reduce greenhouse gas emissions (GHGE). Nevertheless, energy from waste presents a source of conflict between different levels of government, public and the industry. Opposition may argue that energy from waste plants pose health risk to the public, increase the cost of solid waste management, have negative environmental impacts and encourage NIMBY (not in my backyard) attitude. On the other hand, some social actors may hold opposite views because they perceive them as source of income or as effective methods of maximizing resource utilization from waste. Clearly, selecting an appropriate energy from waste strategy in democratic systems of government involves many layers of decisions and requires the construction of effective dialogue mechanisms among many social agents. This paper demonstrates how life-cycle analysis combined with cost analysis can be integrated with conflict analysis models under conditions of uncertainty to select an appropriate policy for energy from waste production from the combustible fraction of the municipal solid waste of Sydney. The results show that anaerobic digestion combined with recycling is the strategy most likely to achieve highest level of environmental benefits while minimising social conflict.
