Solid waste management assessment methods that simultaneously analyze the economic, social and environmental dimensions are limited. Tools are rarely applied in developing countries because of several constraints encountered during their implementation (e.g. lack of data availability and difficulties concerning data interpretation), consequently hampering the development of sustainable solid waste management practices. In addition, the incorporation of stakeholders in most decision-making tools and processes, as well as the availability of credible data in developing countries is often limited. To address these issues, this paper presents one of the first large scale studies, utilizing a tool, named Integrated Assessment Scheme (IAS). Use of IAS provides a holistic, integrated approach evaluating the economic, environmental and social dimensions in order to support the decision making process and to facilitate more sustainable waste management in low and middle-income countries. The use of IAS in the two case studies from Bosnia-Herzegovina and Mozambique suggests its suitability to communities in similar contexts. However, its limitations are also discussed.
