Investigating the feasibility of recovering urea from human urine by Marepula, Hlumelo

“…The successful recovery of urea from human urine could potentially supplement the fertilizers produced from the Haber-Bosch process and address resource depletion. Challenges with waste management could also be addressed by introducing source separation of urine and faeces so that urine can be recycled for urea production. …”

Life cycle assessment of the production of xanthate salts and of their application for ARD mitigation by Kunene, Makhosazane Chucky

“…Xanthate salts are commonly used as collectors in the mineral processing of sulphide ores. In more recent studies, xanthate has also been used in the environmental desulphurisation flotation of sulphidic mine tailings and coal waste, with a view to mitigating acid rock drainage (ARD) risks through the pre-disposal removal of sulphide minerals. …”

Synthesis of 6-Deoxy-6-Amino Chitosan and applications thereof by Sayed, Shakeela

“…Chitin and chitosan play an important role in the context of a biorefinery, where waste is converted into useful products. The introduction of an amine onto chitosan at the C-6 position has led to the synthesis of a highly water soluble chitosan derivative, 6-deoxy-6-amino chitosan. …”
