My supervisors and I conducted a bibliometric analysis and comprehensive mapping of existing urine recycling knowledge and used a novel multi-criteria framework to evaluate whether the development of such a TIS is feasible. Results showed that the rate of publications and knowledge diffusion increased sharply in 2011–2021 compared to 1990–2010. However, the function still has insufficiency in some criteria. ... paper is attached.
