For the case of metals, the declining availability of natural resources and the environmental impacts of continued extraction of primary resources for production activities have forced greater focus on waste streams and recycling activities. However implementing new business models for circular material flows require system-wide changes that will likely involve radically different approaches to doing business and the adoption of disruptive technologies. These new business models will fundamentally challenge the existing view of business models as a way of understanding how businesses do business, and how they create and appropriate value. This paper has two purposes; the first is to present an overview of new 'circular' business models, in particular their relevance to metals. By modifying a typology for sustainable business models we define circular business models as a subset of sustainable business models and consider two exemplary cases to examine the varied characteristics that define such business models for circular flows of metals.business modelscircular economymetalstext::book/monograph::book part or chapter
