Cement production is an energy intensive process. In South Africa the cost of energy increased since 2006, while cement sales have dropped dramatically. It has become important to focus on methods to optimise energy consumption to achieve cost savings in the cement industry. Various methods of reducing production cost by improving energy efficiency are available, but require extended installation periods and high initial capital expenditure. Other methods such as operational optimisation can reduce production cost, but offer limited savings. The aim of this study is to integrate the optimisation of multiple component operations to improve savings and reduce interruption during implementation. Although integrated optimisation models have been developed, no literature could be found on the application of these models in the cement industry. This thesis reports on the development and implementation of an energy management system at four South African cement plants. The total electricity costs were reduced without installing costly infrastructure upgrades. The results summarise the success of the improved production planning. A conclusion regarding the feasibility of this implementation is compiled by comparing the savings achieved by the implementation of the energy management system to other energy saving methods. Recommendations are also made for further study and the implementation of the energy management system in similar industries. / Thesis (MIng (Mechanical Engineering))--North-West University, Potchefstroom Campus, 2013.

Sustainability is one of the most important performance measurements in this fast changing business environment, as climate change and customer satisfaction is becoming real issues that managers have to face. Not only does it reflect the impact the company has on the economy, environment and society but also communicates corporate responsibility and smart business practices to the relevant shareholders. The Johannesburg Stock Exchange Limited (JSE) is the first global stock exchange to compel listed companies to integrate sustainability reporting with their annual report in the form of an integrated report. This requirement came into effect on 1 March 2010. It will enable managers to assess their organisation’s ability to create and uphold sustainability over the short, medium and long terms. It also allows managers and stakeholders to evaluate their business from a holistic perspective to report on a wider context of how it creates value for their shareholders and customers. The GRI identified the global challenges regarding sustainability reporting and launched their first Sustainability Reporting Framework in 2000 to clearly and openly report on relevant sustainability issues. The GRI also provide Sector Supplements that focuses on sector specific performance measurements. The balanced scorecard which celebrated its 20th anniversary in 2012, has been proven to be one of the most influential business management strategies of the last 20 years. Adjustments can be made to the traditional BSC by using an effective social responsibility framework, such as the GRI, to provide a sustainable balanced scorecard. It will express long-term organisational strategies, both financial and non-financial that is linked to sustainability. The oil and gas industry is a multifaceted, global industry and a key player in the South African economy, which has a fundamental impact on safety, health, environmental and social issues. The research was performed based on all the JSE listed companies in this industry based on an observational, ex post facto and descriptive research methodology. The integrated reports for both 2011 and 2012 were obtained and compared against the G3.1 Oil and Gas Sector Supplement indicators. It was found that selected oil and gas companies include sustainability issues in their integrated reports with a focus on social aspects. The contribution of the study was the development of a Sustainable Balanced Scorecard for the oil and gas industry. / MCom (Management Accountancy), North-West University, Potchefstroom Campus, 2014

According to s 23, 24 & 25 of the MPRDA, mining companies must submit a Social and Labour Plan (SLP) when applying for mining rights, and the local economic development (LED) of the SLP must be aligned with the local and district municipality Integrated Development Plan (IDP). The alignment between the SLP and IDP local economic development initiatives provides a platform for investment opportunity, economic growth, poverty reduction and infrastructure development (ICMM, 2006). The main objective of this research was to determine the extent to which the mining SLPs are aligned with municipal IDPs. The research was conducted using a qualitative method for three case studies, a literature review, a documents review (of the SLPs and IDPs), questionnaires and interviews. The mining industry charter gives mining companies targets for the development of local communities through their SLPs. The King reports on corporate governance also give the industry ways to report on corporate social responsibility and sustainability. The local government Municipal Systems Act governs the development of local communities through the development of IDPs as per s 29.There are also debates on the increase of local beneficiation by mining companies, thereby creating jobs and accessing incentives in the form of royalty payments and tax relief. In addition there is a growing demand for a portion of such royalties and taxes to be paid directly into the municipalities to improve the LED and infrastructure challenges. The main challenge with alignment is how mining companies deal with related community grievances and risks, capacity constraints at local government and the DMR, poor stakeholder engagement and the backlog of service delivery. Overall, in the three case studies the KPIs were generally aligned (criteria B) with the municipal IDPs, which indicates that there is a general compliance with the DMR regulations and guidelines. The SLPs, socio-economic background and key economic activities were aligned (criteria A) with the IDPs, while projects and programmes were also generally aligned (criteria B). The negative social impacts were just aligned (criteria C) with the IDPs while no KPI was found to be not aligned (criteria D) with IDP. Some of the initiatives to improve the positive social impacts were the continuous Social Impact Assessment (SIA) throughout the life of mine. Most importantly the research identified that there is a need to improve capacity in local government for dealing with local economic development as this will also aid/improve the alignment of IDPs and SLPs. / M Environmental Management, North-West University, Potchefstroom Campus, 2014

The loss of ecosystem resilience and rangeland (often referred to as veld in South Africa) productivity is a major problem in the semi-arid Savanna environments of southern Africa. The over-utilization of rangelands in the Molopo region of the North- West Province in South Africa has resulted in profound habitat transformations. A common regional indicator of rangeland degradation is the imbalance in the grasswoody ratio, characterized by a loss of grass cover and density with increased shrub or tree density. This can result in major reductions of rangeland productivity for the grazing animal, forcing land users to apply active or passive restoration actions to improve rangeland condition, control the thickening of woody species (bush thickening), mitigate economic losses and restoring the aesthetical value of the Savanna environment for ecotourism and game hunting aspects. This study formed part of the multinational EU-funded PRACTICE project (“Prevention and restoration actions to combat desertification: an integrated assessment”). The first aim of the study was to evaluate locally applied restoration actions using a participatory approach, followed by interviews with certain stakeholders that formed part of a multi-stakeholder platform (MSP) related to the livestock and game farming community in the Molopo. Participants of the MSP ranked indicators according to their relative importance regarding the restoration actions on an individual basis. The individual ranking results were combined with quantitative bio-physical and qualitative socio-economic measurements for each indicator in a multi-criteria decision analysis (MCDA), whereby the alternative actions were ranked according to their relevancy and performance. The results were then shared with members of the MSP in order to stimulate discussion among the members and contribute to the social learning of the project outcome. The overall positive response and acceptance of results by members of the MSP changed the perceptions and objectives of the land users regarding rangeland management. This type of participatory assessment was therefore found to be very promising in helping to identify more sustainable actions to mitigate rangeland degradation in the Molopo Savanna region. There is, however, still an urgent need to create legal policy frameworks and institution-building, to support local-level implementation in all socio-ecological and economic settings, particularly in communal areas. The second aim was to evaluate the effect of two chemical bush control actions (chemical hand- (HC) and aeroplane control (AC)) as well as rotational grazing (RGM) on the Molopo Savanna vegetation. Results show that rangeland productivity, i.e. forage production and grazing capacity, was found to be negatively related to the woody phytomass in the savanna system studied. Bush thickening influenced grass species composition which was commonly associated with a decline in the abundance of sub-climax to climax grasses, respectively. All three actions (HC, AC & RGM) significantly reduced the woody phytomass and increased forage production and grazing capacity. Although AC resulted in the highest reduction of woody phytomass, the highest forage production and grazing capacity was found under RGM. The second highest grazing capacity was found in HC sites, which was due to a high abundance of perennial, palatable climax grass species. Results from this study also show that the patterns and compositions of grass species, grass functional groups (GFGs) and woody densities indicated by RGM and chemical HC, best resemble a productive and stable savanna system that provides important key resources to support both grazing and browsing herbivores. / MSc (Environmental Sciences), North-West University, Potchefstroom Campus, 2014

In this day and age sustainability is gaining increasing importance seeing as this is of utmost importance to stakeholders. Yet, very few people are aware of the true meaning of sustainability. Stakeholders, also being the users of the annual report, need to be aware of the impact a company has on the environment and the society as well as their financial performance in order, among others, to make informed decisions regarding investments. For all financial years ending on or after 1 March 2010, all companies listed on the JSE have to report on sustainability (this is a JSE listing requirement). Yet, no statutory requirement for adherence to reporting standards relating to sustainability exists. This creates the risk that sustainability reports will omit negative impacts or be otherwise misleading, yet the company is still seen as adhering to listing and thus statutory requirements. The Global Reporting Initiative (GRI) developed their Sustainability Reporting Framework in order to serve as a benchmark for measuring sustainability. This Framework includes the Sustainability Reporting Guidelines (including basic principles and standard disclosures that need to be included in the report), Sector Supplements (including sector specific issues) as well as the Technical Protocol (which guides the entity in defining the content of the report). This is currently the only formal guideline available and is widely used around the world. Given the importance of the mining industry in South Africa, this article considers the quality of integrated reporting of the South African mining industry. This is done by undertaking a quantitative, applied, descriptive methodology in order to answer the research questions. Thus compliance with the globally accepted GRI Sustainability Framework has been evaluated and analysed. Using a sample of 13 of the mining companies included in the JSE Top 40 companies, the results show that these companies use the GRI G3.1 Guidelines in producing their sustainability report and that adherence improves annually. Some companies, however, do not apply the Sector Supplements which was designed to include industry-specific impacts. / Thesis (MCom (Management Accountancy))--North-West University, Potchefstroom Campus, 2013

Milton Friedman’s theory of free market corporate responsibility, which states that the maximizing of profits is the only social responsibility a law-abiding business has, is clearly a concept of the past. A concept that is very relevant today, is the concept of sustainable development, which may be defined as development that meets the needs of the present world without forfeiting the ability of future generations to meet their personal needs. This concept recognises that stakeholders and shareholders require forward-looking information to attend to the economic, environmental and social aspects of a business’s activities. Previous research has indicted that the financial performance of a business alone isn’t the sole reason for its success. This demonstrates the change from a single-bottom-line management and reporting approach to a triple-bottom-line management and reporting approach. The Global Reporting Initiative (GRI) developed a Sustainability Reporting Framework that is generally considered the most widely used framework in terms of social responsibility reporting. In this research project, the unique set of business principles and values of co-operatives were analyzed and evaluated, and congruence were found between sustainable development and co-operative governance. Co-operatives in their diverse forms support the fullest participation in the economic and social development of people since they put people at the centre of their business and not capital. The primary objective of this study was to determine the extent to which the GRI guidelines, as a reporting framework, are feasible or applicable to cooperatives as a business model. In this research project, the abovementioned GRI guidelines are applied on a selected cooperative’s activities. The empirical case study, based on the agricultural co-operative Agri- Com, illustrated that the Level C Reporting Framework as per the GRI, can be used very successfully in the co-operative business model. In the case of Agri-Com, it was found that even though it is a co-operative, its primary management and reporting focus remained primarily on the financial aspects. It can therefore be recommended that in this instance, the guidelines per the Level C Reporting Framework, be considered as a method to better embrace the principles of the co-operative business model. / Thesis (MCom (Management Accountancy))--North-West University, Potchefstroom Campus, 2013

The survival rate and life expectancy of infants with complex health needs have increased overthe last decades, and this increases the number of families who have to care for such infants at home. These families seek support in the community setting, and supporting them has a positive impact on the well-being of both the parents and the infant. In South Africa the needs of these parents are not known, and this fact makes it difficult to adequately support them in the community. The aim of this study was to explore and describe the needs of parents of infants with complex health needs in the community setting. Two objectives were set to reach the aim mentioned above: 1) to critically appraise and synthesise the best available evidence on the support needs of parents of infants with complex health needs and 2) to explore and describe parents’ emic perspective on their support needs as parents of infants with complex health needs in a South African context. A sequential mixed method approach was utilised in two phases, here discussed in five chapters. In an attempt to meet objective one, the support needs of parents of infants with complex health needs were determined by means of an integrative literature review from studies obtained through computerised searches of several electronic databases, supplemented by checking reference lists and consultation with experts. This was followed by individual face-to-face interviews with the stated parents in three different settings. The latter addressed the second objective of the study, namely to provide an emic perspective on the support needs of parents of infants with complex health needs in a South African context. The integrative literature review described five main themes on the support needs of parents of infants with complex health needs: need for information, need for parent-to-parent support, need for professional support, need for self-confidence in the care of the infant and need for social support. All of these themes were confirmed in the South African context through the interviews with parents. However, South African parents added an additional theme: the need for normality. The final chapter offers an evaluation of the study and discusses study limitations and recommendations for nursing practice, education and research. / Thesis (MCur)--North-West University, Potchefstroom Campus, 2013.
