- Description: Abstract: The purpose of this study is to examine how SMEs in emerging markets can benefit from the use of big data and to look at challenges that SMEs encounter when using big data. SMEs play a critical role in growing the economy of developing, emerging, and also developed countries. In South Africa, SMEs account for 98.5% of the total businesses. This study is exploratory and adopted a desk-review approach where journal articles and government reports were reviewed. It was found that SMEs that use big data are more profitable, productive, and innovative. SMEs find it difficult to use big data tools and technologies. This study recommends that institutions of higher learning should introduce short learning programs or continuous education programs to train SMEs on how to use big data tools and technologies. The government should provide both financial and non-financial support to SMEs so that they are able to use advanced technologies and compete with big corporations. Future studies should look at refining big data tools and technologies for SMEs to provide them with technologies and tools that they can easily use.

- Description: Abstract: The quantum of minerals extracted from ore is critical for the success of mineral processing, hence the necessity to optimize the process flows in order to recover as much minerals as possible. The aim of this research was to identify bottlenecks and recovery-hampering factors within the comminution and flotation circuits of the concentrator plant at a platinum processing company in Zimbabwe. Modelling and simulation of the circuits were carried using Arena and Limn simulation software to optimize the process flows for improved throughput, maximum mineral recovery and enhanced efficiency and productivity. Alternative configurations of the layout of equipment were experimented on and compared with the original setup. The recommended reconfiguration of the circuits achieved increases of 2.97% in mineral recovery and 4 grams/ton in productivity resulting in a maximized output for the sustainable processing of platinum ore.

- Description: Abstract: Municipal solid waste (MSW) data sources in Harare metropolitan province show significantly varying data with regards to generation and composition. The sources of variations include data lumping; exclusion of MSW managed outside the formal system and remain uncol-lected, lack of a clear definition of what constitutes MSW within the Zimbabwean context as well as temporal variations. It is therefore important for waste generation and characterisation studies to be undertaken building upon the already existing datasets to ensure the accuracy and reliability needed for data credibility for use in MSW management planning.

- Description: Abstract: This paper assesses the gap between an established QMS at the South African national electricity company in the metering division compared to ISO 9001:2015 requirements standard and finding ultimate ways to close the gaps. The study follows a quantitative approach with questionnaires distributed and semi-structured interviews conducted to collect the data for more reliability and validity of the study. A sample of 200 employees was selected form the metering division, however, the response rate translated to 82.5%. It is found that some of ISO 9001:2015 clauses are not respected, and the expected requirements were not met in terms of process approach, with 77% of respondent indicating that there is a lack of resources and competencies, while 73% indicated that there is a deficiency in design and operation compatibility. Recommendations made on the failure in the process approach include the use of internal and external audits and the development of quality awareness programs of metering employees.

- Description: Abstract: A reliable and sustainable means of human transportation is vital for the world’s increasing pollution emissions and congestions on the motorways. The research aimed at and focused on developing an affordable electric drive train for cycles using the principle of Continuously Variable Transmission (CVT) to provide an interminable number of speed ratios by varying the pulley diameters. The planetary gears designed and installed within the CVT chamber provided a locking mechanism for the ring gear to provide forward transmission to the rear wheel where motion was stepped up through an open differential gear to propel the cycle forward. For stability and ease of manufacture and assembly, a tricycle concept was chosen and developed as a sustainable and alternative means of transportation. The developed electric drive train provides a ‘green’ and affordable means of human transportation in a world geared towards the elimination of pollution.

- Description: Abstract: Six municipal solid waste management options (A1– A6) in Harare were devel-oped and analyzed for their eutrophication impact potentials under the Life Cycle Assessment (LCA) methodology. All the options started with waste collection and transportation to a cen-tralized waste treatment centre where a combination of various municipal solid waste manage-ment and treatment methods were considered under the different options. Results show that landfilling and material recovery for reuse and recyle are the only MSW management processes that contributes to negative eutrophication potential giving options that had landfilling (A1, A4 and A6) an overall edge. The doubling of recycling rate under A5 and increasing it to atleast 25% under A6 result in below zero eutrophication impact potentials. Results reveal that anaero-bic digestion and incineration contribute to increased eutrophication potential under all the op-tions they were considered hence need for further assessments considering other impact catego-ries to determine the most sustainable option.

- Description: Abstract: Conventional refrigerators impact on the environment contributing to ozone depletion and global warming. Common refrigeration methods make use of Chlorofluorocarbons (CFCs), Hydro chlorofluorocarbons (HCFCs) and Hydrofluorocarbons (HFCs) which all have negative effects on the environment. Legislation in some countries has been enforced to ban the use of some refrigerants due to their harmful effects. It was therefore prudent to develop alternative methods of refrigeration such as thermos-acoustic, magnetic or thermoelectric that do not utilise the harmful refrigerants. Alternative refrigeration methods can be applied in a variety of industries such as the food, agriculture and health establishments. This research established the disadvantages of conventional refrigeration and the potential for alternative refrigeration methods for the storage of vaccines. A portable thermoelectric prototype refrigerator was developed from locally available and sustainable materials at an estimated cost of $129. Although its performance was below that of conventional refrigerators, it managed to accomplish the desirable range of temperature for storing and transportation of vaccines, positively impacting on the environment by avoiding the harmful effects of refrigerants.

- Description: Abstract: Technology rejection phenomenon manifests itself differently across different societies. Over the past two decades, low income households in Soweto have persistently rejected prepaid electricity meters. Until now, the basis of the rejection in the region remains scientifically underexplored. We therefore conduct an exploratory study of pertaining prepaid meter rejection in Soweto. Through triangulation research and survey approach, 88 households based in Orlando East and Diepkloof were interviewed by means of a questionnaire. Our findings show that three aspects contributing to this phenomenon, namely: lack of quality consultation and education, the high levels of electricity consumption, and unattainable politically motivated promises are the main reasons that currently fuel prepaid meter rejection. We emphasise that the current state of the Free Basic Electricity (FBE) (2003) policy also fuels rejection, as it remains socio-economically inadequate and irrelevant for indigent households. We therefore note the need for an FBE policy review and update as well as the establishment of a policy monitoring committee to ensure implementation and enforcement.

- Description: Abstract: The appropriate handling of materials in manufacturing is essential for the realization of reductions in direct and indirect costs. This research was carried out at a plastic manufacturing company in Zimbabwe where polymer pellets are used to produce plastic packaging. An in-depth work study was carried out at the plant followed by the feasibility, review and analysis of available and affordable conveying systems. A semi-automated pneumatic conveyor system comprising of a prime mover, feeder, and mixer was designed to replace the manual handling of materials. The analysis and eventual development of the optimal conveying system assisted the company in not only freeing up space for the uninterrupted movement of materials, but also improvements in safety and reduction in transportation and operational costs for the sustainable recycling and manufacture of plastic packaging. The research also contributed to the company’s product quality and variability.

- Description: Abstract: Poor municipal solid waste (MSW) management practices impact negatively on freshwater availability in terms of both quality and quantity. A review on the MSW practices currently being practiced and their impacts on water resources management in Harare was car-ried out to give recommendations towards sustainable MSW management and reduce the pollu-tion of water bodies. There is urgent need for the development and implementation of a local level integrated MSW management plan tapping from the national plan that was pronounced in 2014. Such a plan should incorporate material and energy recovery with the best option combin-ing anaerobic digestion of biodegradable MSW and incineration of the non-biodegradable MSW fraction. Legislative reforms to enforce source separation, the prohibition of dumbing waste at dumpsites together with the landfilling of biodegradable waste need to be urgently institutional-ized.

Such a plan should incorporate material and energy recovery with the best option combin-ing anaerobic digestion of biodegradable MSW and incineration of the non-biodegradable MSW fraction. Legislative reforms to enforce source separation, the prohibition of dumbing waste at dumpsites together with the landfilling of biodegradable waste need to be urgently institutional-ized.

- Description: Abstract: Source separation of municipal solid waste (MSW) is an integral part of sustaina-ble and integrated MSW management. In Zimbabwe, the national solid waste management plan of 2014 provide for source separation under goal 2 and public education for awareness raising on the importance of source separation under goal 7. This provides the necessary commitment and necessity for source separation at national level. This study reviewed the available opportu-nities and limitations for MSW source separation in Harare. Such opportunities for source sepa-ration that exists include the availability of a national plan, MSW composition which eases source separation of organics to either anaerobic digestion or composting, recyclables and non-recyclables of a low heating value amenable to incineration with energy recovery. However, limitations with regards to enabling legislation, municipal capacity to spearhead source separa-tion in light of their failure to provide MSW receptacles to over 75% of households, equipment and technical expertise exist.

- Description: Abstract: The demand for electricity has escalated and cannot be fulfilled by conventional energy sources alone. There has been a rising demand to seek new renewable energy sources. Although solar and wind energy are the most cost effective renewable energy sources, they are unreliable due to the sporadic nature of their occurrence, if implemented as standalones. In Zimbabwe, solar street lighting has been implemented since 2014 as a solution to the erratic power supplies and outages. Wind potential in Zimbabwe has been identified at elevated heights, with Gweru having the maximum power density of 115 W/m2 at 50 m hub height. This paper presents the optimization of the design of a hybrid renewable energy system (HRES) of solar and wind energy to power a 160W streetlight. The system consisted of a wind turbine, photovoltaic modules, charge controller, battery bank and lights. The system sizing was done in Excel using wind and solar data obtained from the database, HOMER Software Package and PVSyst. The 3D streetlight was modelled using Inventor Professional and a working prototype was manufactured. The results showed that the HRES reduced the energy storage requirements by 38.75% with an overall cost reduction of 14.4%, relative to a standalone solar streetlight. The diffuser effect to the turbine was experimentally assessed, showing 69.3% increase in turbine power output and a 50% decrease in energy storage requirements. Further research can be carried to improve the reliability for standalone systems.

- Description: Abstract : Composting and AD of biodegradable waste were assessed for their benefits from literature and environmental impacts using the life cycle impact assessment procedure. Literature review findings indicate an overall edge for AD over composting largely due to its renewable energy production capabilities, reduced exhaust emissions and cost effectiveness considering the entire MSW life cycle. LCIA results show that both AD and composting leads to increases across the four impact categories considered namely, global warming, human health, eutrophication and acidification. AD however showed lower contributions than composting to global warming, human health and acidification. Composting only showed lower contribution than AD in regards to eutrophication. Overall study results indicate an edge for AD over composting in treating and managing biodegradable fraction of MSW generated in Harare and its surrounding urban and peri urban environments of Chitungwiza, Epworth, Norton and Ruwa.

- Description: Abstract : This study explores the temporal trend in electricity consumption since the introduction of prepaid meters in low income households of Soweto, and compares the findings with high income households. Monthly electricity consumption data (over 96 months: 2007-2014) on 4427 households in Soweto, for both low and high income households, was collected from Eskom. Using a simple linear model to analyse consumption trends in low income households, we ascertain that electricity consumption has decreased by 48% since the inception of prepaid meters. Nonetheless, it is noted that 60% of household incomes are spent on electricity bills, which is way above the threshold set for energy poverty. Comparatively, high income households consume lower electricity than low income households do. Overall, the prepaid meter programme is producing expected results for Eskom but remains a challenge for low income households, which are still entrenched in energy poverty. We call for an energy policy that is tailored for each income groups and the formulation of laws and policies to protect the energy vulnerable households.

- Description: Abstract: South Africa, being a developing country, experiences the impact of global competition which has pushed many organizations to develop plans to respond to a continuous competitive global market. The restaurant, fast food, and catering sector is broad within the service industry involving independent restaurants, quick service restaurants and fast food outlets, outsourced catering companies, just to name a few. This study’s objective is to establish the importance of focusing on the fundamentals of quality management practices and the usefulness of leadership practices in the management process of the above-mentioned sector. This study included a quantitative research method under which an empirical investigation was executed following the literature review. The study consisted of the analysis of data collected from questionnaires administered to 65 restaurants in Gauteng, South Africa. After results analysis and interpretation, it is concluded that the functions of management were not well integrated, mainly the leadership functions. Hence, a need to improve specific aspects of the foundations of management approaches in the restaurant, fast food and catering sector is required.

The study followed a mixed approach, combining both the qualitative and quantitative design approach. In order to collect data, interviews with the employees that constituted the sample were conducted before they later responded to a questionnaire to collect qualitative data. Results demonstrates that the company does not use JIT as a manufacturing strategy. This explained the difficulty experienced with many aspects of the production such as: demand management and forecasting, supply chain relationship and inventory control. A recommendation made in this study was to actively apply JIT in the manufacturing process as this practice would help the company improve its performance as far as the inventory control, the relationship with suppliers and the demand management and forecasting are concerned.
