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/m3. The plastic is melted and WFS is used to produce a paste for the moulding of building material.

Problem solved

Plastics are...

Interferon Induced proteins with Tetratricopeptide repeats (IFIT) proteins are a family of antiviral proteins that have been shown to confer immunity against viral infection. IFIT proteins have been shown to be conserved in vertebrates, with homologues having been identified in several organisms.

A cost-effective tip appendage design that reduces tip leakage vortices in axial flow fans to improve fan performance. The appendage is robust in that it is applicable to various axial flow fan designs and can be installed on currently operational units through retrofitting due to its simplistic...

This invention relates to a system that continuously measures and monitors the dynamic behaviour of turbomachine blades in order to provide early warning of incipient blade failure. This would enable management to take corrective action in order to prevent failure and downtime. The system can be...

Air quality is a concern worldwide. Consequently, efficient means to monitor air pollutants are critical. Current commercially available carbon-based sorbents used for sampling volatile organic compounds (VOCs) in air typically require solvent extraction prior to analysis, and they cannot be reused...

The invention is a leakage detection system for water pipelines installed in partially saturated soils. Most soils in South Africa and the rest of Africa are partially saturated because the water table is usually deep. Given the large amount of water lost from water distribution systems worldwide...

Researchers at Stellenbosch University have developed a groundbreaking new polymer having permanent antimicrobial properties. The compound can be spun into nanofibers for the production of filter elements or membranes, which successfully filter out micro-organisms and eliminate harmful bacteria.

A...

Power plant efficiency is generally determined by projected electricity tariffs and power plant life cycle costs during the design phase. This technology can be installed below wet cooling tower fills to significantly enhance the thermal performance of the cooling towers, resulting in a reduction in...

A cost-effective, highly efficacious trough assembly for collecting and removing drops with minimal air-side pressure drops for use in evaporative heat exchangers or cooling towers. The innovation reduces water consumption and required fan power. The elimination of a rain zone reduces the...

Short chain fructooligosaccharides (scFOS) are prebiotics used as a food supplement to improve dietary health in humans and animals. FOS are also used in the food industry as low-calorie sweeteners and added to food products to improve their organoleptic properties.

Global demand for FOS is...
