Efforts to integrate living organisms in the design of new technologies are often motivated by prospects of greater sustainability and increased connection with more-than-human worlds. In this project, we critically discuss these motivations by analysing the vast and mostly hidden ecologies of more-than-human organisms implicated in a biodesign lab experiment. Through the lenses of labour theory, we investigate the extent to which organisms’ bodily functions and relationships can be subsumed into capitalist modes of production. In order to help reveal and map out the network of more-than-human contributors to biodesign, we develop a workshop method and a labour provenance analytical framework that identifies five types of more-than-human labourers, stretching from the centre to the periphery of biodesign.
