The invention relates to the use of maghemite nanoparticles at pH less than 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In conventional AMD treatment, these pollutants are only removed at higher pH, and that requires costly alkaline
The Bambara Groundnut, or round bean, is widespread in Africa where it is known by various names. It has potential as a cash crop, owing to its nutritional composition, functional properties and antioxidant potential. Consequently, we at CPUT have used the Bambara Groundnut as a raw material to
The North-West University (NWU) has pioneered the novel use of Europium-Tellurium-Oxide (ETO) in the production of clean energy. ETO is a light-chargeable catalyst material that exhibits sustained and enhanced activity after light excitation has ended. Its unique characteristics present an

Currently, the ARC have three commercial cultivars, Ratel, Steenbok and Tredou. Ratel consists of a medium growth period whereas Steenbok consists of a short growth period with good drought tolerance making it suitable for areas with a dry climate. Tredou is the newest addition to the ARC cultivar

The invention relates to an automated process for fabricating nano and micro structures using high temperature superconducting quantum interference device (SQUIDS). This method overcomes the high cost and complexity in the manufacturing process of superconductors for a commercial scale or mass

An irrigation sprinkler riser technology which comprises of a flexible tubular body which is installed to join from the lateral water supply pipe to the sprinkler head, allowing adjustable positioning of the sprinkler at various angles or directions by means of an adjustable knob. The body of the

Conventional irrigation sprinklers which are fitted with rises pipes above the ground are prone to mechanical damage and disorientation. As a result, the lifespan of the irrigation system is shortened or the potential of irrigation systems to optimally irrigate the required surface areas are

Water hyacinth (Eichhornia crassipes) is an aquatic weed which has one of the highest growth rates of all plants in the world. This fast-growing plant causes numerous problems in water bodies. These problems are related to navigation, recreation, irrigation and hydropower generation. The complete

The product offers healthy bread naturally fortified by the nutrition of Amaranth. The bread contains high micronutrients including iron, zinc, vitamins A and C from the indigenous Amaranth species. The product offers a good opportunity for nutritional value and health benefits. Also, it provides

Green Coal is environmentally friendly coal briquettes produced from discarded fine coal, bio-char material, and proprietary chemical binders. The briquette reduces sulphur emissions during combustion by approximately 50%, while also increasing the burning effectiveness. The bio-char addition to the

Indusdx® is a biodegradable disinfectant which has been enhanced by the addition of a natural anti-microbial compound. This environmentally friendly industrial disinfectant and biocide has been specifically formulated for use by manufacturers. It can be added to cleaning products, paint and other

In the manufacture of textiles, clothing and leather goods, using a nanoparticle catalyst, this one-step wastewater treatment system activates a powerful oxidiser. This produces sulfate radicals in the wastewater which will degrade the inorganic pollutants. These highly reactive nanoparticles are
