TL;DR: In this paper, three methods for defining the contents of the analysed system in this respect are described: process tree, technological whole system and socio-economic whole system, and examples are described in the application's multi-output processes and cascade recycling, and the authors concluded that system boundaries must be relevant in relation to the purpose of an LCA, that processes outside the process tree in many cases have more influence on the result than details within the process trees, and that different methods need to be further compared in practice and evaluated with respect to both relevance, feasibility and uncertainty.
