The main objectives of this subproject are threefold:
- To contribute to the understanding of the potential trade-offs between material recovery objectives and energy optimisation strategies in terms of financial and economic costs.
- To contribute to the formalisation and understanding of current and future waste management and resource recovery strategies from a financial and economic point of view.
- To contribute to the proposal of eco-efficient strategies to recover materials and energy from waste and gain knowledge how to overcome barriers to implementation for the time horizons 2020, 2035 and 2050 from an economic point of view.
To achieve these objectives the research plan of this subproject consists of the following four main steps:
1. LCC and relevant actors: A life cycle costing framework will be developed by selecting the most relevant financial and economic indicators for waste management systems with a focus on resource recovery (energy and materials) and be applied to three cases studies taking into account the relevant actors.
2. Financial analysis for Swiss waste streams: The results of the LCCs of all three case studies will be aggregated and associated to industrial and municipal waste streams in Switzerland. Furthermore, financial indicators will be developed from the LCC results and aligned to the LCA results of SP1 and fed into the optimisation models of SP1 and SP2.
3. Actors and associated costs and benefits: Relevant actors and stakeholders, defined in step 1, will be associated with related costs and benefits, derived from the LCC results, on the level of the Swiss waste management system. Additionally cost structures and factors as well as economic drivers and barriers will be determined.
4. Financial and economic indicators for optimisation: Finally, by providing these results to the waste management optimisation of SP1 and SP2, robust and sustainable energy and material recovery strategies can be derived for Switzerland.
