Jenna Senecal

Jenna Senecal-Smith
Jenna Senecal completed her PhD at the Department of Energy and Technology at SLU in June 2020 and is continuing with research as a post-doc at the department while running a spin-off company from her group's research called Sanitation360. Jenna specializes in safe nutrient recycling - particularly from converting human excreta into a valuable, safe fertilizer. She currently has two projects: > REWAISE - implementing urine-drying prototypes in Skåne - check out the toilet at VA SYD's head office in Malmö > N2Brew - implementing full-scale urine recycling on Gotland with local partnerships
