[email protected] Summary Material flow analysis (MFA) has been an effective tool to identify the scale of physical activity, the allocation of materials across economic sectors for different purposes and to identify inefficiencies in production systems or in urban contexts. However, MFA relies on the invisibilization of the social drivers of those flows to be able to perform its calculations. In many cases therefor, it remains detached from the for example urban processes that underpin them. This becomes a problem when the purpose of research is to design detailed recycling schemes or the like, for which micro-level practice knowledge on how material flows are mediated by human agency is needed.
