Resource modelling in a circular economy context
Licentiate thesis, 2023
The work presented builds on two studies. Article I is a review and mapping of the flows and processes that CE indicators capture in the product lifecycle. The indicators are also applied to a wide number of cases to determine how the indicators differ and to identify their potential limitations. In article II a dynamic MFA model is developed and applied to a multiple reuse and recycling case of lithium-ion batteries. The study examines how this circular solution could affect raw material and battery flows over time. Finally, the two studies are synthesised into a method comparison of CE indicators and dynamic MFA. The comparison focuses on similarities and differences between the methods with regards to the object of study, how temporal aspects are represented, system boundaries, and the type of results provided. While CE indicators provide information on variations of resource use over the product lifecycle, dynamic MFA informs on how CE strategies can affect stocks and flows of products and materials over time. Amongst other things, the results emphasise the importance of capturing the temporal dynamics of material flows when evaluating CE strategies, e.g. how the availability of secondary resources could change over time or assessing how a transition towards a more circular economy can play out over time.
