Description

What if the future of sanitation depended on scent? In this bold and unconventional scientific exploration, Christian Starkenmann tackles a largely overlooked challenge: rethinking the smell of toilets to improve the lives of billions of people. At the crossroads of sensory science and molecular chemistry, he shows how carefully designed fragrance accords can transform our relationship with the most taboo odors—and influence human behavior in profound ways.
