Research and development on the recovery and reuse of nutrients found in human excreta and domestic wastewater has intensified over the past years, continuously producing new knowledge and technologies. However, research impact and knowledge transfer are limited. In particular, uptake and upscaling of new and innovative solutions in practice remain a key challenge.
This paper presents a methodological plan for a systematic map of literature. It describes innovative methodology for literature mapping using machine learning and knowledge brokering tool for building policy-relevant, readily available and up-to-date online evidence platform on technologies for recovery and reuse of plant nutrients from human excreta and domestic wastewater.
