Sustainable Waste and Resource Management to Support the Energy Turnaround (wastEturn)

Doctoral thesis of Melanie Haupt

The overarching aim of this joint project is to optimise the contribution of the Swiss waste management system to the ‘energy turnaround’, i.e. the foreseen shift from non-renewable to renewable energy sources and a reduction in overall energy consumption. This requires improving the system’s environmental and economic performance while developing strategies that are socially robust. The joint project wastEturn, therefore comprises four subprojects (SP) which target these different aspects: In SP1 the overall resource potential and the environmental performance of the Swiss municipal solid waste (MSW) management system are assessed and subsequently optimized. In SP2, the implementation and operation of single- and multi-site industrial waste-to-energy systems is addressed. The need for investments and the financial viability and value creation of the waste management system on both a national and sectorial level is evaluated in the third SP. In SP4, the societal barriers and drivers for the transition to more optimal waste management are analysed, and the development of robust strategies for the practical implementation is facilitated by the integration of expert knowledge and stakeholder perspectives.
