Fly ash is a waste by-product generated by coal-fired electricity power stations. Due to its environmental impact, there is a growing need for safe and sustainable methods of fly ash disposal. One effective approach is the beneficiation of fly ash through the production of zeolites—a class of

Some 13,000 ships enter South Africa’s eight ports annually. These ports process some 10,000 containerised loads per day. Many industries rely on imports and exports via the country’s ports, where a safe port environment, with minimal disruptions while loading or offloading cargo, is critical

The invention The invention uses plastic waste and Waste Foundry Sand (WFS) to produce building and construction material with a density of between 1700 and 1750 kg/m 3 . The plastic is melted and WFS is used to produce a paste for the moulding of building material. Problem solved Plastics are vital

Invention The invention relates to a food ink for use in a 3D printing process for the manufacture of food items, using extrusion-based printing techniques. Problem solved The printer can make foods with elaborate decorations and designs more easily than doing it by hand. It can enhance diversity

Radar technology is well suited to solutions such as those to protect helicopters. The CSIR was approached by SAAB Grintek Defence, a leading supplier of aircraft self-protection suites, to collaboratively develop a radar-based hostile fire indicator sensor to add to its existing platform protection

A camera, roughly the size of that used for CCTV, can locate gunshots by detecting potassium emissions from the muzzle flash. Dubbed, ‘The K-line camera’ (K being the symbol for potassium on the periodic table), it can be integrated into a CCTV network in a hotspot area for gun-related crime

The technology is a membrane for treating acid mine drainage that is reproducible and can handle large discharges of acid mine drainage. It is suitable for implementation in a filtration cartridge setup that allows for the reclamation of metals which can then be recycled and used for other
