(University of Pretoria, 2023-08-17)Wax is often used as a processing additive in polymer compounding, particularly in thermoplastic processing, due to its ability to improve processability. Wax acts as an external lubricant in the polymer melt, reducing the ...
-
(University of Pretoria, 2024-02-26)Active pharmaceutical contaminants which are constantly released into both surface and ground water through wastewater treatment plants (WWTP), run-off from agricultural fields, excretion, and disposal of unused or expired ...
-
(Springer, 2024)Please read abstract in the article.
-
(University of Pretoria, 2023-09-20)As climate change continues to take the centre stage among issues of global discuss, carbon heavy industries including construction and agriculture continue to discover possible ways to foster the implementation of cleaner ...
-
(Wiley, 2023-05)BACKGROUND : Pyrolysis process is one of the most effective recycling methods due to its ability to recover products like gas, oil and char with oil being the major/important product. The shortcomings of waste tyre-derived ...
-
(University of Pretoria, 2024-01-31)The research investigated the characterisation of a cost-effective active solar still by implementing active solar still recommendations suggested by Marais (2018) and external condenser design improvements identified in ...
-
(Springer, 2024-02)In this study, the photocatalytic activity of nanomaterials Ag/AgX (X = Cl, Br, I) is reported. Highly efficient silver halide (Ag/AgX where X = Cl, Br, I) photocatalysts were synthesized through a hydrothermal method. The ...

(Nature Research, 2023-04-13)Biodesulfurization (BDS) was employed in this study to degrade dibenzothiophene (DBT) which accounts for 70% of the sulfur compounds in diesel using a synthetic and typical South African diesel in the aqueous and biphasic ...
-
(Elsevier, 2024-11)Organochlorine pesticides have been widely used in agriculture to control agricultural pests. Although effective in controlling pests, organochlorine pesticides present numerous hazards to ecosystems and human health due ...

(Emerald, 2024)PURPOSE – The adverse impacts of climate change coupled with rapid informal urbanization in the Southern African region are increasing the vulnerability of already sensitive population groups. Consequently, these urban ...
-
(University of Pretoria, 2023-12-12)This dissertation presents the development and implementation of a model predictive control (MPC) system for a coffee roasting process, to optimise roasting quality while minimising energy consumption. The study involved ...
-
(University of Pretoria, 2024-02-05)Nanocellulose fibres are known to enhance the mechanical properties of biopolymers by acting as a reinforcing additive. However, the formation of irreversible hydrogen bonds and subsequent agglomeration upon drying means ...
-
(University of Pretoria, 2024-01-29)Nitrogen and phosphorus form the backbone of most lifeforms on earth, however, improper management of these nutrients has devastating effects on the environment. These effects can be lessened by the use of the anaerobic ...
-
(University of Pretoria, 2023)This study focused on an SO2 abatement plant for a platinum group metal (PGM) smelting electric furnace. A systematic approach, using a simulated model of the plant, was followed to investigate plantwide control measures ...
