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

Using a metallurgical waste product, the invention consists of a method to treat acidic water from mining sites. The treated water can be used for industrial applications or, with additional steps, be treated for potable usage. Water is currently a scarce resource in South Africa, and the depletion

Activated Carbon: Local Production Using Local Nuts The invention describes a novel method of producing activated carbon from locally available nut shells. The invention provides a method to carry out carbonation and physical activation simultaneously via a pyrolysis process. This process produces

Biosurfactants produced by Pseudomonas aeruginosa SB24 (rhamnolipid congeners), Bacillus amyloliquefaciens ST34 (surfactin and bacillomycin L analogues and homologues) and pigmented (P1) and non-pigmented (NP1) Serratia marcescens strains (serratamolide and glucosamine derivative homologues) were
The Department of Chemical Engineering at Stellenbosch University has developed a novel solvent-based process for extracting cannabinoids directly from plant-wax waste streams generated during industrial processing. The method uses a simple but effective combination of two immiscible solvents, one
