Learn MoreConstruction Waste Is
Not the End
Every tonne of fine ash we process is a tonne diverted from landfill — and a step toward a South Africa that builds with what it already has. We turn environmental challenges into construction solutions.
Read Our ESG PositionFine ash from construction processes is one of South Africa's most significant environmental challenges. Ronkela's process directly addresses this by converting waste into certified, high-value products — measurably reducing landfill burden.
Construction waste feeds directly into Ronkela's production — closing the loop and eliminating disposal waste entirely. Our Ashcrete products embody this principle at every stage.
Our Ashcrete prefabricated housing and I Lock systems have been used in thousands of government-subsidised homes — delivering affordable, durable, and environmentally responsible housing solutions.
