“I learned to believe in myself and accept failure and rejection as part of the journey.” These words echo through the powerful journey of Mahlatse Mamaila, the trailblazing South African entrepreneur and founder of INO-Biodiesel, a startup that’s redefining the biofuel landscape in Africa.
From a curious student with an eye for sustainable solutions to a dynamic leader driving clean energy innovation, Mahlatse’s path was anything but linear. But her unwavering resilience, belief in a greener future, and commitment to community upliftment have made her a force to be reckoned with in the renewable energy sector.
Planting the Seeds of Purpose
Growing up in Limpopo, South Africa, Mahlatse was always connected to the land—its abundance, its challenges, and its potential. This connection would later become the foundation of her business vision. After earning her degree in Chemical Engineering, she noticed an urgent need for cleaner, more sustainable fuel alternatives in South Africa’s heavily fossil-fuel-dependent economy.
Instead of following a traditional corporate route, Mahlatse dared to dream differently. She imagined turning everyday waste—like used cooking oil and agricultural by-products—into something powerful: biodiesel. This dream gave birth to INO-Biodiesel, a clean energy startup that now serves as a beacon of innovation and impact in Southern Africa.
INO-Biodiesel: Greening the Economy, Empowering Communities
INO-Biodiesel is not just a business. It’s a mission-driven movement.
The company collects waste cooking oil and other organic materials from restaurants, communities, and businesses, and transforms them into high-quality biodiesel fuel. This environmentally friendly alternative reduces greenhouse gas emissions and air pollution, while also helping to manage waste more sustainably.
But the true genius of Mahlatse’s model lies in its circular impact. INO-Biodiesel employs and empowers local communities, especially women and youth, by integrating them into the biofuel production value chain—whether through waste collection, processing, or distribution.
Mahlatse’s leadership is rooted in inclusivity and education. Her company conducts regular community workshops, teaching people about renewable energy, waste recycling, and entrepreneurship. For her, true innovation is not just about technology; it’s about social transformation.
“I believe sustainability must start with people. We’re not just fueling vehicles—we’re fueling livelihoods, hopes, and futures,” Mahlatse often says.
Conquering Doubt, Embracing Failure
Building a green-tech business in a sector dominated by large fossil fuel corporations was not easy. From lack of funding and limited public awareness to skepticism about biodiesel’s viability, Mahlatse faced numerous obstacles—many of them rooted in systemic barriers against women in science and entrepreneurship.
She encountered rejection from investors, had her ideas overlooked in male-dominated boardrooms, and at times, questioned whether her vision was too ambitious for the moment.
But Mahlatse turned each setback into fuel for growth.
“I learned to believe in myself and accept failure and rejection as part of the journey,” she shares. “Each ‘no’ taught me something new. It pushed me to refine my model, improve my pitch, and most importantly, keep showing up.”
Her grit paid off. INO-Biodiesel secured grants, built strategic partnerships with municipalities and eco-conscious businesses, and attracted support from green-tech incubators. Today, the company is scaling operations across South Africa, with eyes set on expanding throughout the SADC region.
Awards, Accolades & Global Recognition
Mahlatse Mamaila’s efforts haven’t gone unnoticed. She has been featured in Forbes Africa 30 Under 30, Mail & Guardian’s Top 200 Young South Africans, and Global Cleantech Innovation Program (GCIP) for her groundbreaking work in clean energy. In 2024, she was named a UN Women Climate Champion, cementing her status as a global thought leader in sustainable innovation.
Her work has also inspired a new generation of African youth to view science and entrepreneurship not just as career options, but as powerful tools for societal change.
A Green Future Fueled by Purpose
Mahlatse envisions a future where renewable energy powers every rural and urban community in Africa, where waste is no longer wasted, and where women lead the charge in engineering, innovation, and environmental justice.
“We need to build systems that work for people and the planet. Africa has all the ingredients—we just need the courage to use them,” she says with conviction.
Through INO-Biodiesel, Mahlatse Mamaila is not only changing how South Africa thinks about fuel—she’s changing the narrative for African women in STEM and entrepreneurship. Her journey proves that when passion meets purpose, and resilience meets innovation, there are no limits to what can be achieved.
