Prithvi Simha
My PhD research focuses on the safe recycling & valorisation of nutrients from source-separated human urine. I work with the design and implementation of drying technologies to convert urine into a dry, hygienic, and high-quality fertiliser. I also work with user acceptance, perceptions, and attitudes to new sanitation systems and technologies.
