Analysis of potential small satellite launch operations at the Denel Overberg test range.
(2022)One of the primary objectives of the South African First Integrated Rocket Engine (SAFFIRE) programme of UKZN’s Aerospace System Research Group (ASReG) is to develop the capacity for orbital injection missions to Low Earth ... -
Development of catalysts for possible hydrogenation of xylose to xylitol.
(2022)This project aimed to synthesize and characterize a novel catalyst for the transfer hydrogenation of xylose to xylitol. A literature review revealed that palladium supported on an aluminium-tin mixed metal oxide support ... -
Biogasoline production by catalytic cracking of waste cooking oil.
(2023)Government, Heads of State, and international organizations gather from time to time to investigate and implement strategies required to eradicate global warming and address environmental issues. The principal causes of ... -
Investigating the effects of wood chemistry and cooking conditions on pulp properties at a dissolving wood pulp mill.
(2021)Pulp viscosity is the main criteria used to determine the endpoint of the pulping process in acid bisulphite pulping for production of dissolving pulp (DP). However, pulping performance is highly dependent on the relative ... -
Establishment of a micro-biorefinery in a rural community: beneficiation of food waste into high value materials.
(2023)Farmers are faced with great challenges such as ever rising costs of fertilizers, pesticides, natural disasters, climate change and many more factors that affect the quality and quantities of produce per season. Regardless ... -
Establishing a bioconversion process for the production of succinic acid using industrial feedstocks.
(2022)One of the leading challenges of the current global situation is the decline of non-renewable, fossil fuels. Due to this rapid depletion, there is a shift towards replacing petrochemical products with equivalent, ideally ... -
Carbon dioxide encapsulation in methane hydrates.
(2022)Coal mining and petroleum refining processes face extreme pressure under climate change and global warming threats. Hence alternative sustainable and renewable energy sources must be made available for the rising energy ... -
Process simulation, optimization and economic valuation of waste tyre pyrolysis for fuel production.
(2023)Management of waste tyres is increasingly becoming a global challenge; the problem is only projected to get worse in future as worldwide tyre production is continually on the rise in response to the growing global population. ... -
Removal of wastewater contaminants by adsorption using iron on carbon foam.
(2022)The dyes in textile effluents have a deleterious impact on water bodies and impede photosynthesis by decreasing sunlight penetration. This work examined the adsorption capacity of an iron oxide sorbent immobilised on carbon ... -
Characterization and analysis of keratinous material from waste chicken feathers as protein ingredient for animal feed.
(2022)Keratin is one of the most abundant proteins, which is derived from wool, feathers, nails, hair, and other sources. Chicken feathers are a well-known keratin waste by-product, produced in large quantities by poultry ... -
Beneficiation of pulp and paper mill sludge: production of cellulose nanofibrils (CNFs).
(2022)Depletion of landfill space, the cost of waste disposal, and environmental concerns are pushing Pulp and Paper Mills (PPMs) to make changes and improvements in the way waste is handled. Pulp and paper mill sludge (PPMS) ... -
Techno-economic assessment of algae conversion to biofuels.
(2023)One of the most promising biomasses for the production of biofuels is microalgae. This is because microalgae have a high growth rate and a highiCO2icapture ability when compared to other biomasses. Furthermore, biofuels ... -
Decentralised sanitation to fill the gap in urban wastewater treatment within the eThekwini Municipality: a focus on tertiary treatment in vertical down-flow constructed wetlands.
(2022)South Africa’s bulk sanitation infrastructure is failing, and there is an urgent need to look at other appropriate sanitation solutions. Moreover, there is no data on the proportion of population with access to safely ... -
Co₂ solubility measurements and modelling in amine-NMP solvent blends.
(2022)In this study, solvent blends of monoethanolamine (MEA) or 2-(2-aminoethoxy)ethanol (DGA) with N-methyl-2-pyrrolidone (NMP) or water (H2O) were selected for investigations of carbon dioxide(CO2) solubility due to the high ... -
Phase equilibria studies on chemical mixtures encountered in the natural gas industry.
(2022)Natural gas processing involves removing impurities from the gas streams. These impurities include carbon dioxide, nitrogen, hydrogen sulphide, water vapour, mercury, and others. These impurities must be eliminated from ... -
An analysis and control of volatile organic Compound (VOC) emissions from petroleum storage tanks.
(2022)Climate change is a growing phenomenon with its effects becoming more prominent to life on earth. According to the latest report by the Intergovernmental Panel on Climate Change (IPCC), some of the effects of climate change ... -
A comprehensive investigation of existing sanitation helminth enumeration methods with the aim of producing an international standard.
(2022)TeHelminth testing in faecal sludge should be consistent so data are comparable. New faecal sludge treatments for on-site toilet technologies are constantly being developed in order for municipalities in developing ... -
Kinetic mechanism study and waste tyre characterisation for valuable chemicals production.
(2022)Researchers have extensively investigated waste tyre pyrolysis kinetics and mechanisms. However, available literature shows limitations as the studies were primarily aimed at tracking the devolatilisation of the main ... -
Characterisation of faecal sludge from urine diversion toilets: impact on black soldier fly larvae growth.
(2022)The area managed by eThekwini Municipality in KwaZulu-Natal, South Africa, was extended in 2002 to include approximately 80 000 households without basic sanitation. The municipality adopted urine diversion dehydrating ... -
Techno-economic assessment of decentralised waste beneficiation in South Africa.
(2022)The introduction of the waste hierarchy promotes the diversion of waste away from landfills towards value-adding opportunities. However, there is no clear methodology for the comparison of waste beneficiation pathways for ...
