POSTMASBURG
Reimagining entrepreneurship from waste to worth
When refuse trucks stopped collecting household waste in Boichoko Postmasburg, residents had no choice but to burn the rubbish, causing severe smoke contamination.
For the then 11-year-old Lesedi Monnanyane, the pollution from the dumpsites ignited a lifelong pursuit of transforming waste into opportunities. “There was something fundamentally wrong with us burning all this waste,” he recalls. “We were destroying value and harming our own health at the same time.”
Lesedi’s entrepreneurial journey began long before he understood the term sustainability. At just 11, he earned pocket money by cleaning neighbours’ yards. His aunt, who collected bottles for recycling, taught him that waste could hold worth. By 15, he had officially registered Sky-High Kaila Enterprise, starting with simple waste collection. Using prize money from school science and entrepreneurship fairs, he began to bootstrap his business and look for ways to pivot into different innovation and technology spaces.
Everything changed when Lesedi discovered Anglo American’s Zimele’s enterprise-development programme in Postmasburg, where he gained mentorship, business training and eventually a R1.3 million loan to expand his operations. With that support, Sky High, expanded their workforce and invested in chemical mixer equipment that makes eco-friendly liquid products as well as a rapid composting system machine that transforms food waste into fertiliser within 24 hours. Within three years, he had fully repaid the loan, proving that investing in young entrepreneurs from rural and township communities is not a risk, but an opportunity. It also demonstrated that youth-owned enterprises in Postmasburg can partner successfully with multinational companies. “Lesedi represents the transformative power of combining entrepreneurial drive with structured support,” says Larisha Naidoo, Head of Anglo American Zimele.
Today, Lesedi’s work extends beyond entrepreneurship. Through the Sky-High ecosystem of ventures, he is developing modular bioenergy hub frameworks that convert alien invasive biomass, organic waste and h**p into different products such as h**p bricks, synthetic fuels, biochar and energy pellets. These hubs are designed not only to produce clean energy, but also to restore soils, save water and generate environmental credits, turning waste streams into economic value. Lesedi strongly believes that development will come from regenerative mining and industrialising to a just low carbon economy. He is currently completing his postgraduate studies in Sustainable Development at Stellenbosch University to realise that vision.
Lesedi’s work has already earned international recognition. He was named among The Earthshot Prize’s Top 100 Young Climate Leaders in Africa in 2024 and again shortlisted as a 2025 Earthshot Prize Nominee. “I see myself as a pracademic - someone who learns by doing and testing ideas in real contexts,” he says.
For young entrepreneurs, his advice is simple: “Just start. You don’t have to have it all figured out. Clarity comes through action. Every step teaches you something new.”
From the village of Groenwater-Stasie in Postmasburg to postgraduate halls in Stellenbosch, Lesedi Monnanyane is proving that regeneration is more than a theory, it is a practice. Guided by the belief that we should leave things and people better than we found them, he is shaping an economy that replaces waste with worth, restores dignity through enterprise and transforms places that were left behind into landscapes of possibility.
