Economic recovery of biobutanol-a platform chemical for the sugarcane biorefinery.
(2018)In recent years, the South African sugar industry has faced challenges, such as drought, low prices and labour issues that have impacted negatively on the perceived sustainability. The adoption of the sugarcane biorefinery ... -
The effect of particle properties on fluidized bed hydrodynamics and entrainment.
(2007)This study focuses on the effect that particle properties (size, density and shape) have on fluidized bed hydrodynamics and entrainment rate. The experimental work was carried out using two Plexiglas columns having ... -
Environnmental life cycle assessment of potable water production.
(2001)This study investigates and compares the environmental burdens of two different methods for producing potable water by using the environmental life cycle assessment (LCA). The first method, for the production of potable ... -
The evaluation of ozone technology to reduce the concentration of polychlorinated biphenyls (PCBs) in contaminated soil.
(2011)Polychlorinated Biphenyls (PCBs) are hazardous and toxic chemicals to both humans and animals. In the late 1960’s PCBs were discovered to be a harmful pollutant which could cause environmental contamination due to its ... -
Evaluation of paper substrates for microfluidic application in medical diagnostic kits.
(2018)Recent studies in the biomedical field have shown the use of paper in microfluidic analytical devices. However, no studies have been undertaken to ascertain what type(s) of paper substrates are ideal for such microfluidic ... -
The evaluation of the fluidised bed combustion performance of South African coals in the presence of sorbents.
(2007)The Fluidised Bed Combustion (FBC) technology has been widely used internationally for power generation. This technology has good fuel flexibility and reduced S02 emissions with dry sorbent (Limestone or Dolomite) addition. ... -
Exploring the effectiveness of separation of pith/fibre fractions in sugarcane bagasse briquetting.
(2019)Abstract available in the PDF. -
Extension of a multi-criterion performance indicator model for post combustion Co2 capture using amine solvents.
(2018)Energy generation by carbonaceous fuel combustion has been identified as one of the predominant sources of CO2 emissions. Many scientists and researchers believe that rising CO2 levels have an adverse effect on the ... -

Extraction of essential oils from vetiver (vetiveria zizanioides) grass.
(2012)Vetiver grass is a viable vegetative absorbent and erosion barrier; in addition the valuable oils extracted from its roots are playing an increasing role in the perfume, food and pharmaceutical industries. The quantity and ... -
Flue gas desulphurization using natural calcium based sorbents.
(2013)Power generation from coal combustion serves as a major source of energy however this process has detrimental environmental effects. SO₂ is a destructive pollutant and is oxidized with water vapour to form sulphuric acid ... -
Fluidised bed gasification of spent soda and sulphite liquors from the paper industry.
(2004)The pulp and paper industry uses pulping chemicals for the treatment of bagasse, straw and wood chips. Spent liquor or effluent liquor, with high carbon content is produced and sent to chemical recovery to recover pulping ... -
Fluidization and sedimentation behaviors of nanoparticles.
(2020)A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 to 100 nanometers in diameter. Nanoparticles were used by artisans since prehistoric times, albeit without knowledge of their ... -
Forward osmosis of stored urine.
(2016)Source separation of urine from domestic waste water provides a sustainable way of managing nutrient and water recovery from urine. This study was performed in the context of the Bill &Melinda Gates (BMFG) foundation’s ... -
Fractionation and valorisation of bark extractives from Eucalyptus species.
(2018)The notion of zero-waste in industrial production processes of widely used materials has gained momentum, as industries aim to gain revenue from waste materials which were previously considered as waste. Tree bark from ... -
Gas-phase ethylene polymerization studies using a magnesium chloride-supported Ziegler-Natta catalyst.
(2006)The gas phase polyethylene production process is the most recently developed and boasts many -
