Material flow analyses

When analysing product portfolios of product groups in companies, or when setting priorities for product policy (as is currently being done with the European Union’s Eco-Design Directive), a need arises to use material flow analyses rather than an individual Life-Cycle Assessment. A material flow analysis is ultimately a system comprising several or many simplified LCAs. Here, as in PROSA’s other tools, care should be taken to follow a methodologically uniform procedure.
