The cleantech solution developed by Tshwane University of Technology is a water purification system that utilizes locally sourced maize tassel, a waste material discarded by farmers. The technology combines the maize tassel with carbon nanotubes to form activated carbon composites, which effectively remove pollutants from water, providing safe drinking water in rural agricultural areas. The solution is unique as it repurposes a waste material abundantly available in South Africa, offering a cost-effective alternative to traditional activated carbon used in water purification. The system targets the removal of herbicides, which can be harmful to human health. The initiative aims to address the lack of clean and pollutant-free water supply in rural and semi-urban areas, producing an estimated 3 million liters of water per month. The potential impact is significant, promoting environmental sustainability, recycling, and providing clean water to communities.

Rubber Nano Products (RNP) possesses advanced technology that enables the development of chemically specific vulcanization activators using sulfur. These activators belong to various accelerator classes, determined by the specific chemical species that form the active component of the accelerator. The innovative RNP technology allows for the utilization of different substrates, making it possible to create activators from a wide range of materials commonly used in rubber production, including stearic acid. The use of RNP products offers several benefits, including the reduction and optimization of zinc oxide and zinc content in the manufacturing of rubber articles. Moreover, these products facilitate lower cure press temperatures, resulting in energy savings. The coactivators used in RNP formulations enable exceptional property performances that go beyond those typically seen in standard ZnO2 rubber formulations.
