In some places such as South Africa, the US and Ireland, there is still a poor public perception of Energy-from-Waste. Lack of transparency during the decision-making process or not inviting residents and stakeholders to be part of the project as well as lack of information exchange between the operators and the clients may lead to poor public acceptance. Developing scientifically based sustainability metrics to give a sound basis for the discussions might also facilitate greater acceptance. Further, a proper decision framework integrating all the main aspects of sustainability (economy, environment and social) is an enabler to ensure that the developed strategies are not sub-optimized in favour of short-term solutions. This workshop series combines informative workshops on regionally relevant waste management systems with the participation of stakeholders in development of a life cycle sustainability framework to consider the most relevant sustainability indicators. The workshop series will identify sustainability indicators to be considered in the Task 36 work programme including the Case Study on Environmental performance of different waste management strategies and the Report on Sustainability.
