A young South African researcher has developed an innovative biodegradable material made from agricultural waste, offering farmers a more environmentally friendly alternative to conventional plastic.
Onndinadaho Rasilwela, a chemical-engineering researcher at Tshwane University of Technology, created the product using materials including sugarcane bagasse and maize stalks that might otherwise be discarded.
Known as “Biomulchies,” the material is designed for use as agricultural mulch. Farmers use mulch to control weeds, retain moisture and regulate soil temperature around their crops.
Unlike conventional plastic mulch, which can remain in farmland and contribute to long-term pollution, Biomulchies is designed to break down naturally in the soil after use.
Rasilwela’s innovation won first prize at the 2026 Green Youth Indaba in South Africa. She received R150,000 to support the project and help move the idea closer to wider use.
Her achievement demonstrates how young African innovators can transform agricultural waste into useful products while supporting farmers, protecting soil and creating opportunities within the green economy.
