Pollution, resource depletion, and to a lesser extent, global warming called into question mass consumption. Political (e.g., politicians), media (e.g., TV broadcasters, tech giants), and supranational entities (e.g., United Nations) nudged societies into alternative consumption forms that have been deemed more sustainable, such as collaborative consumption (CC). This paper aims at proposing a theoretical-empirical model that explains the materiality of sustainable collaborative practices through a bike-sharing system. The study further analyzes how connections, mediations, and inductions occur between individuals, platforms, and providers in collaborative consumption. This study examines the bike-sharing system of Porto Alegre in Southern Brazil and Vancouver's bike-sharing in Canada. We tracked these actants using the Actor-Network Theory through 30 interviews with consumers and managers. The findings suggest a dynamic ecosystem of mechanisms that mediate interactions and enact "sustainable collaborative consumption (SCC)" through digital solutions and physical equipment. The findings illustrate actors' partnerships and hybrid practical relations, establishing connections, inductions, and mediations. The results reveal that SCC is positively influenced by three avenues: 1sustainable individual actions; 2digital platforms; and 3sustainable physical equipment. Moreover, the research contributes to a new view of understanding the collaborative economy in a sociotechnical view.
