100 People & Organizations in Circularity to Follow in 2025: Part 18 of 25

After 10 years in #circularity, I have compiled a list featuring 100 people and organizations, who I think you should follow. It is being released in 25 posts and acts as an unconventional zero waste alternative to an advent calendar — packed with little stories and wisdoms.

In this eighteenth post, I am focusing on people and organizations pushing for circularity in the #medical, #sanitary, and #chemical sectors.

69) Isabela Bonatto works as a consultant for the UN Environment Programme, and she is an ambassador for the Circular Movement. Isabella’s work is centered around water, sanitation, energy, and waste challenges. In light of this, she has expertise in humanitarian work, reverse logistics, waste management, recycling, and the circular economy. Isabela writes articles about the opportunities the circular economy presents for the Circular Movement’s blog.

70) Jan Carel Diehl and Tamara Hoveling conduct research into how to implement circularity into hospitals and medical devices at the Delft University of Technology. Jan Carel co-leads the interdisciplinary research consortium for the NWO (Dutch Research Council) project on evidence-based strategies to create circular hospitals. Through her PhD research, Tamara works to advance circular design in the development of medical devices. The two recently co-authored a paper titled “Mapping circular economy product and material flows in healthcare: A visual taxonomy”. The paper sets out a visual taxonomy for circular healthcare flows, which acts as a tool to help the health sector “make better decisions, collaborate more effectively, and apply circular strategies with confidence and common understanding”.

71) Prashant Prahlad and Nadine Audi co-founded Diva'Me. Their goal is to make periods safe, sustainable, and clean for all women. Diva'Me creates reusable menstrual products, without plastics that harm women’s health and the environment. They produce beachwear, intimate skincare, panties, and swimwear for use during periods. The FemTech company is also developing an AI-based app to track menstrual and emotional health, as well as environmental impacts during menstruation.

72) Sofía Lara Schlezak works with the United Nations Institute for Training and Research (UNITAR). Her work revolves around the management of chemicals and waste – including e-waste, plastics, and polychlorinated biphenyls (PCBs). Sofía Lara works with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS), and other inventories and registers for industrial chemicals. She also supports UNITAR with its work on the implementation of key international waste instruments – including the Stockholm, Basel, Rotterdam, and Minamata Conventions, as well as the Global Framework on Chemicals.
