The invention relates to the use of maghemite nanoparticles at pH < 5 to remove sulphate, manganese, copper, nickel, cobalt and zinc metal ions from acid mine drainage (AMD). In a conventional way of AMD treatment, these pollutants are only removed at higher pH and requires costly alkaline chemicals

This technology utilises the unique properties of a specific type of biosurfactant to selectively recover metals from solution. Using comparatively low concentrations of biosurfactant, the metals can be recovered (and potentially valorised), and the surfactant can even be recycled back for further
The DarkLight™ Catalyst is an advanced, biosynthesised titanium dioxide (TiO₂) photocatalyst that functions efficiently without the need for visible or ultraviolet light. Developed through a green synthesis process using natural extracts from Hibiscus sabdariffa, the material features an oxygen
The PureLite Reactor™ provides a highly efficient and customisable platform for various applications. Its energy-efficient LED light sources, advanced control systems, and versatile design give researchers precise control over photochemical reactions, making it a vital tool in environmental science
The innovation describes a process for removing lead from a liquid such as contaminated water. The liquid is brought into contact with a PbrD protein which binds lead ions present in the liquid. The bound lead ions can then be recovered, for example as an insoluble salt or compound such as lead
CloudHarvest ™ is an innovative solution that tackles the rising frequency of droughts and water shortages caused by climate change. It offers a sustainable way to influence weather patterns and water availability in vulnerable regions. During severe droughts, cloud seeding has been proven as an
The technology is a membrane-based system developed from waste expanded polystyrene (EPS) using electrospinning to create a nanofibrous material with superhydrophobic (water-repelling) and superoleophilic (oil-attracting) properties. It enables crude oil adsorption, recovery, and membrane
The invention uses maghemite nanoparticles at pH levels below 5 to remove sulphate, manganese, copper, nickel, cobalt, and zinc ions from acid mine drainage (AMD). In traditional AMD treatment methods, these contaminants are usually removed only at higher pH levels, which requires expensive alkaline
This technology offers an innovative and eco-friendly method for producing ferric chloride (FeCl₃), a commonly used coagulant in water purification, by recovering Fe(III) from acid mine drainage (AMD). AMD is a significant pollutant generated by mining activities and typically contains high levels
