Aart van den Beukel, Managing Director and Founder of Safisana (https://safisana.org/), has over 20 years of entrepreneurial experience in the circular economy.

Today Safisana serves the Ashaiman community of 50k + people with improved sanitation, generating employment, increased availability of electricity, organic fertiliser and food.
