My research focuses on the safe recycling and valorisation of nutrients from source-separated human urine. I am developing a technology that converts human urine into dry, hygienic, and high-quality solid fertiliser. I also work with user acceptance, perceptions, and attitudes to new sanitation systems and technologies.

Forskning

Productive On-site Sanitation System : New Value Chain for Urine Based Fertilizer
UDT 2.0 - Urine Dehydration Technology for Sanitation 2.0
MORTTI - Mobile nutrient recovery in field conditions
