The transition towards a circular economy (CE) is seen as vital for developing sustainable places. CE is used as a new buzzword, as well as an inducement to innovate and change socio-economic practices, by a diverse set of actors to meet sustainability and other goals. Genuine transformation, we argue here, requires those practices to seriously alter discourses and metrics. We adopt a material critical-relational perspective, drawing on the assemblage notion of (counter)actualisation. Our contribution is both conceptual and empirical. Conceptually, we develop an assemblage-based framework featuring practices, discourses and metrics. Empirically, we apply this to national CE policy and local initiatives in the Netherlands. Our results point out both passions and challenges to come to a genuinely transformative discourse and use of metrics.@en

Blockchain emerged as a well-defined technological object with limited applicability applications (e.g. Bitcoin). Embraced by more and more ‘stakeholders’, Blockchain has turned into a bounty of possibilities and promises. This raises the question whether Blockchain is turning into an overextending, affective ‘hyperobject’. Adopting a post-ANT topological perspective, and using mixed-methods analysis, this paper traces Blockchain's recent developments in the Netherlands. A media analysis of newspaper items shows a telling divide between stakeholders (including incumbents) stressing Blockchain's radicalising prospects and those (notably involved knowledge and policy workers) warning of its overhyping and lack of governance capacities. A detailed analysis of strategies and operations of the key enabler, the Dutch Blockchain Coalition, reveals how much effort has gone into face-to-face encounters and communication to frame and script the object. Yet, this also causes Blockchain to proliferate in all kinds of directions, turning into a hyperobject beyond the reach of intellectual and practical grasp.
