- Description: It is typically said that there are two questions that political philosophy seeks to address: ‘who gets what?’ and ‘who decides on who gets what?’ South Africa, along with much of the rest of the world, has answered the second question badly and currently ranks as one of the world’s most unequal societies. Counter-intuitively, South Africa maintains a social-political order that (re)produces this inequality along with great enthusiasm for ubuntu, an African ethic that at a minimum requires that we treat each other humanely. However, due to the view that ubuntu has been co-opted in support of South Africa’s unjust system, ubuntu has largely been ignored by radical thinkers. The aim of this thesis is therefore to explore the possibility of an ubuntu-based political philosophy, with the core assumption that political philosophy is rooted in ethical theory. Three tasks are therefore undertaken in this thesis. Firstly, ubuntu is articulated as an ethic. Secondly, it is compared to similar Western ethical theories in order to determine if there are distinguishing characteristics that make ubuntu a more appropriate founding ethic for South African political philosophy. Finally, whether ubuntu can find real-world applicability will be assessed by looking at the way ubuntu has been used in the law

- Description: There is increasingly stringent legislation on the environmental impact of energy production from coal combustion, and this has led to growing pressure to reduce the emission of greenhouse gases (GHGs). Thus, there is a significant need to develop and implement clean coal combustion technologies that would reduce the environmental gas pollutants. For power generation, the co-firing of biomass fuels at conventional coal-fired power stations is recognised as one of the low-cost, low-risk options to achieve significant reductions in GHG emissions. When coal is co-utilized with biomass there is added attractiveness because the biomass is CO2 neutral, and there is interest in using waste biomass and microalgae. Thus, the co-combustion of coal and biomass for energy production results in pollutant reduction, especially in the emissions of NOx, SOx, volatile organic compounds and polyaromatic hydrocarbons. The synergistic activity observed for toxic organic emissions is not well understood and is thought to involve chemical interaction between the volatiles from each fuel coupled with possible catalytic activity from the inorganic constituents of the fuels. The characterization of co-firing products and gases emitted from coal and microalgae (particularly the Scenedesmus strain) co-combustion has received limited attention. Therefore, this study seeks to understand possible interactions occurring during co-combustion of coal and Scenedesmus microalgae (Coalgae®). Additionally, the study aims to determine the effect of co-firing coal and Scenedesmus microalgae on CO2, SO2 and NOx emissions. The term “Coalgae®” refers to the mixture of coal and microalgae biomass. The study looks at physico-thermal characteristics as well as CO2, SO2 and NOx emissions of various coal-microalgae blending ratios by mass; 100:0 (coal), 95:5 (Coalgae® 5%), 90:10 (Coalgae® 10%), 85:15 (Coalgae® 15%) and 80:20 (Coalgae® 20%). Characterization techniques carried out included proximate and ultimate analyses, Fourier-transform infrared (FT-IR) and Scanning electron microscopy and X-ray energy dispersive spectroscopy (SEM/EDS). For combustion studies two techniques were applied. Low heating rate was obtained through a Thermogravimetric-Mass spectrometer analysis (TG-MS). Other combustion experiments were performed on the five lumpy fuels (coal and Coalgae® 5% - 20%) exposed to the flame in a fixed-bed combustion reactor. The emission concentrations of CO2 (%), NOx (ppm) and SO2 (ppm) of coal and Coalgae® blends were measured during the combustion of the five materials using a Lancom 4 portable flue gas analyser. The mass reduction (g) and temperature (°C) at the reactor exit were recorded during the combustion tests to compare the combustion behaviour of the four mixtures to that of raw coal. TG-DTG curves of coal and microalgae confirmed that the combustion behaviour of these materials was different. Coal showed one reaction during the combustion process, while microalgae and the Coalgae® blends showed three reactions. A significant reduction in activation energies of 160.4 kJ/mol, 159.6 kJ/mol, 151.3 kJ/mol, and 134.2 kJ/mol for Coalgae® 5% - Coalgae® 20%, respectively, compared to coal (161.3 kJ/mol) was achieved. The lowering of activation energy could be attributed to the relative fixed carbon content. SEM morphology images of ash obtained from the combustion of coal and Coalgae® 5% - 20% confirmed changes in devolatilization and combustion behaviour of solid raw fuel. The ash of Coalgae® blends had higher fluxing elements (Fe, Ca, K and Mg) than coal and this shows possibility of slagging and fouling in combustion systems. The Coalgae® blends showed a synergistic effect due to different combustion characteristics of coal and Scenedesmus microalgae. The combustion results obtained from the fixed-bed reactor showed significant reductions in concentrations of CO2, SO2 and NOx emissions for Coalgae® blends compared to baseline coal. Microalgae reduced CO2 emissions from baseline coal by 14.9%, 19.5%, 23.5% and 31.4% for Coalgae® 5%, 10%, 15% and 20%, respectively. SO2 reductions of 1.9%, 10.6%, 15.8% and 18.2%, and NOx reductions of 22.4%, 26.1%, 24.4% and 16.9% were achieved with Coalgae® 5%, 10%, 15% and 20%, respectively. Moreover, the combustion efficiency of Coalgae® blends increased significantly by up to 14.5% from baseline coal (86.4%) to Coalgae® 20% (98.9%). Based on the above findings, the co-firing of coal and Scenedesmus microalgae biomass was necessary for the reduction of CO2, SO2, and NOx emissions. As such, Coalgae® blends can be considered as alternative fuels in any coal driven process for energy generation. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: Waste tyre is becoming a global environmental problem due to challenges in its disposal management and the fact that it poses fire hazards and metal leaching risk. Waste tyre can also breed mosquitos if it traps water thereby becoming an environmental health problem. There is also a portion of unused tyre in a waste tyre that is valuable and should be recycled. In South Africa waste tyre recycling is in three industries, one of which is crumb rubber where waste tyre is applied into various sized particles called crumb rubber. Crumb rubber can be applied in environmental remediation as an organic and inorganic pollutants’ adsorbent. Considering the fact that South Africa’s environment is loaded with heavy metal pollutants due to contributions by mining and agriculture as examples, it is postulated that crumb rubber produced in South Africa could be used to remediate the environment of these toxic metals. In this study adsorption of Pb (II) and Cu (II) from the synthetic waste water using waste tyre crumb rubber produced in South Africa was studied. Crumb rubber was activated using aqueous NaOH (0.02%) to make crumb rubber wettable followed by it being treated with 0.02 % acidified KMnO4 for modification of its ability to sorp positively charged metal species. Trial sorption experiments on 50 mg / L Cu (II) were successful with sorption of over 70% in 250 minutes. Final optimization of the sorption of combined Pb (II) and Cu (II) was studied using a full factorial design and optimum conditions of sorption were found to be pH 5.4; [metal] 0.617 mmol / L for Pb (II); and pH 5.4; the optimization of Cu (II) was found to be pH 5.4; [metal] 0.777 mmol / L. In Pb (II) sorptions the mechanism of adsorption on the activated crumb rubber was found to be following the Freundlich model indicating that the adsorption seemed to occur on a multilayer adsorbent, while the mechanism of copper(II) adsorption on to the activated crumb rubber was found to be following Langmuir model, indicating that the adsorption seemed to occur on a monolayer. With adsorption percentages ranging from 98.2 % to 100.0 %, for Pb (II), the crumb rubber produced under the conditions of this study, can be used in South Africa for selective removal of Pb (II). , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: Investment in youth development for a country like South Africa, where social issues such as unemployment, lack of quality education, high levels of school dropouts, difficulty in accessing post-secondary education and training are of high prevalence is crucial. There are different strategies that key players in youth development such as the government, private sector and NGOs can implement in advancing the youth. This study sought to examine one of these strategies which is mentorship.

- Description: Investment in youth development for a country like South Africa, where social issues such as unemployment, lack of quality education, high levels of school dropouts, difficulty in accessing post-secondary education and training are of high prevalence is crucial. There are different strategies that key players in youth development such as the government, private sector and NGOs can implement in advancing the youth. This study sought to examine one of these strategies which is mentorship. Consequently, the purpose of this study was to scrutinize the essential role that a mentorship program can play in progressing youth development. The objectives of this study are as follows: to investigate the key challenges facing the teenage girls that participated on the Vision4 Mentorship Program; to investigate the effectiveness of the strategy of using mentorship programs as a tool in achieving youth development in Motherwell, Port Elizabeth and to come up with the recommendations with the view of addressing some of the problems faced by the youth in Motherwell, Port Elizabeth.

An assessment of the key factors that may impact the future demand for red meat in South Africa

- Description: The global human population is estimated to be in excess of nine billion by the year 2050, and the added population is expected to put further pressure on already over- extended resources such as food and water. Increased demand, positive growth and record high prices should be encouraging for the red meat industry. Despite all the positives such as the growth in the world population and the consumer’s ability to spend, the popularity of red meat around the world and in South Africa is continually declining in favour of white meat and other non-meat proteins. Although red meat will often be the most expensive component of any diet, the nutritional value that red meat offers as part of a healthy and balanced eating plan, should not be understated. This study intends to identify and assess factors that may impact on the future sustainable demand for red meat. Sixty-two adults were surveyed through an electronic questionnaire to assess their views on red meat consumption in South Africa. A set of 52 questions were deduced from the main focus and objectives. The data was analysed and conclusions derived from it. The results show that the demand for red meat is sustainable if outlets selling red meat are accessible and the preference for red meat remains, even with stiff competition from substitutes like pork, chicken and vegetables. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021
