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
