SpheriCity

Funded by the National Science Foundation Convergence Accelerator Program, SpheriCity aims to optimize circularity, from the city up, transforming the linear consumption model of raw material extraction, production, use, and disposal that dominates the global economy. In Phase I of this project, a circularity path was connected and converged across multiple materials and scales in two large metropolitan areas. In Phase II, the newly updated and expanded CAP framework is converging circularity across plastics (exploring alternatives) and the built environment in eleven more cities. Phase II also expands this work by training local implementation partners, and further developing a novel dynamic data portal and large language model (LLM).
