Optimization of waste reduction in the construction sector: the case study of the eThekwini Municipality in South Africa.
(2021)Although South Africa is on the road to a greener future through the Act No. 26 of 2014: National Environmental Management: Waste Amendment Act 2014, the South African Waste Report (Department of Environmental Affairs, ... -
A policy framework for the implementation of sustainable construction in Nigeria.
(2020)The practice of sustainable construction improves the quality of life of the citizenry. Based on the need to realise the tripod of economic, environmental and sociological improvements, many countries have realised the ... -
Fabrication of dye-sensitized solar cells using heteroatom-doped reduced graphene oxide, and metal oxide-based nanocomposites as a counter electrode or photoanode.
(2021)Recent advancements in technology have led to an exponential increase in global energy demand. Non-renewable energy sources have been widely used to meet this demand; however, they are prone to depletion ... -
Evaluation of using local information from donor catchments to improve performance of selected deterministic and empirical design flood estimation methods in South Africa.
(2021)There are a number of design flood estimation methods routinely used in South Africa. Flood Frequency Analysis (FFA) remains the preferred technique in instances where adequate records of observed data are available. ... -
Building a framework for the sustainable African city of the future.
(2021)The increase in rural to urban migration rates have resulted in the rapid urbanization and uncontrolled growth of modern day cities. This trend is expected to continue in the coming years, thereby increasing the demand for ... -
The potential of provitamin A-biofortified maize and sweet potato, and bambara groundnut for improving the nutritional status of rural communities in KwaZulu-Natal, South Africa.
(2020)The double burden of malnutrition, under- and over-nutrition, is a serious health problem and a leading contributor to the global disease burden. Undernutrition presents as wasting, stunting, underweight and micronutrient ... -
Evaluation of forward osmosis technology for the treatment of selected concentrated brines.
(2021)Abstract available in PDF. -
Cellulose nanocrystals: plant design for up-scaled production and applications in green construction materials.
(2021)Two main problems were addressed in this project. Firstly, upscaling technologies from the laboratory scale to industrial scale is difficult in the absence of pilot scale facilities. This research entailed the development ... -
Thermo-physical properties of alkanolamine-ethanol hybrid solutions: experimental measurements and modelling.
(2021)This study presents the measured densities (!), viscosities (") and refractive indices (nD) of Monoethanolamine (MEA) + Ethanol (ETOH), N-Methyldiethanolamine (MDEA) + ETOH and Diethanolamine (DEA) + ETOH mixtures over ... -
Groundnut variety replacement, market structure, marketed surplus and demand for improved varieties in Malawi: the case of smallholders and traders.
(2020)Groundnut is an important crop for the Malawian agricultural sector. It has the potential to increase agricultural farm incomes and contribute to improving food security for the predominantly maizebased food production ... -
Addressing traffic congestion and throughput through optimization.
(2021)Traffic congestion experienced in port precincts have become prevalent in recent years for South Africa and internationally [1, 2, 3]. In addition to the environmental impacts of air pollution due to this challenge, ... -
Design and optimization of a separation process for butanediol dehydration for use as a biofuel.
(2020)Ongoing research in incorporating renewable biofuels into the transport sector are fuels that can be used interchangeably with petroleum derived fuels. These fuels are termed “drop-in” fuels and can be used in the pure ... -
Artificial intelligence based design optimization for improving diversity in wireless links.
(2021)Abstract available in PDF. -
Application of crop models in assessing impact of climate change and identifying adaptation options in a tropical environment in Ethiopia.
(2021)Abstract available in PDF. -
Separation of noble gas mixtures of (Xe, Ar and Kr) using gas hydrate technology.
(2020)The separation and purification of xenon from xenon + argon + krypton mixtures is an important research area owing to the increasing industrial demand for the gas. While cryogenic distillation, membrane technology and ... -
Sustainable plant-derived coagulating agents in a heterogeneous platform for front-end water purification.
(2020)Chemical coagulants have been associated with having adverse economic, health and environmental impacts. Many rural communities do not have access to specialised coagulating agents and infrastructure for water treatment ... -

(2021)Abstract available in PDF. -
Application of the truncated perturbed chain-polar statistical associating fluid theory (tPC-PSAFT) to alcohol/alkane mixtures at high pressures.
(2020)Constitutive equations, such as equations of state (EoS) characterize mathematical relationships between state functions under set physical conditions and are imperative for the accurate design of chemical processes ... -
Low temperature optimization of copper recovery from e-waste.
(2021)The purpose of the report is to provide a detailed investigation on the recycling of copper from waste electronic Printed Circuit Boards (PCBs). The roles played by leaching agent, temperature, time, particle size, and ...
