The target for renewable energy as a share of total consumption is 40% by 2020 according to the EU-Directive 2009/28/EC on the promotion of the use of energy from renewable sources. European countries have to comply with the Landfill Directive 1999/31/EC, and with the Waste Framework Directive 2008/98/EC to considerably reduce the landfilling of the biodegradable portion of municipal solid waste. The use of biowaste as a resource will help to reach the above mentioned targets regarding the use of renewable energy and the reduction of landfilling as a part of the biodegradable part of the MSW. Biowaste management should be considered from the economic, environmental, and social perspectives. The resulting complexity constitutes an important barrier to the implementation of biowaste planning projects. In order to promote the development of renewable energy sources, the potential amount of biowaste must be assessed and, based on that, the optimal transformation into an energy method has to be found. The aim of this thesis is to develop, apply, and evaluate a methodology for the integration of cleaner production principles into biowaste management. In particular, this thesis focuses on a methodological development addressed to policy- and decision-makers specifically (1) to evaluate biowaste management options, (2) to assess the sustainability of bioenergy projects, and (3) to find an optimal solution for biowaste treatment given the conditions in a particular region. This thesis applies a modelling approach based on a combination of Multi-Criteria Analysis and Correlation and Regression analysis and on a combination of Multi-Criteria Analysis and System Dynamics. The results of this research can be addressed to different target groups and levels: the governments, waste and energy sectors, scientists and environmental activists. The proposed approach, integrating the methodologies, provides a greater understanding of, and more insights into, the waste sector. Multi-Criteria Analysis and System Dynamics and Multi-Criteria Analysis and Correlation and Regression analysis methodologies combined in the way proposed here can be used not only for waste management, but also in other fields dealing with technology based decision-making in complex and dynamic systems.
