In a world where access to clean water remains one of the most pressing challenges, innovation often emerges from necessity. Murendeni Mafumo, the founder of Kusini Water, has taken an unconventional approach to solving this crisis—using macadamia nut shells to purify water. His mission is simple but ambitious: to bring safe, drinkable water to underserved communities across South Africa and beyond.

In this episode of The Mashstartup Podcast, we sit down with Murendeni to explore his journey from a small village in Limpopo to leading a groundbreaking social enterprise. With a background in chemistry and years of experience in water research, he has pioneered a sustainable, low-energy filtration system that is changing lives. Kusini Water isn’t just about clean water—it’s about empowerment, economic development, and a new way of thinking about resource management.

Join us as we discuss the science behind Kusini’s innovative filtration technology, the impact of water scarcity on communities, and the power of entrepreneurship to drive real change. Murendeni shares the lessons he’s learned along the way, the challenges of scaling a purpose-driven business, and why he believes solving Africa’s water crisis is a collective responsibility.
