Indigenous knowledge systems related to solid waste management in economically marginalized communities have been largely overlooked in the scientific literature, even though the indigenous communities of developing nations struggling to manage solid waste rely on these practices. It is startling that indigenous solid waste management practices are...
In recent years, a surge in studies concerning indigenous knowledge (IK) has been observed, yet a clear definition of IK remains elusive. Discrepancies in international studies lead to fluid interpretations of the concept. The present study seeks to delineate the key elements characterizing knowledge as either indigenous or foreign to a specific co...
Introduction and Aim
The uThongathi Estuary was found to be in a poor ecological state and the water pollution was due to the discharge from the wastewater treatment plant, industrial, agricultural and residential sectors of Tongaat. The aims of this paper were therefore to explore the need for phytoremediation, as well as to show the importance of...
Many households have restricted access to various energy types and, as a result, are faced with a daily challenge of having to make appropriate energy choices to meet their energy requirements. This paper aimed to review empirical studies on the households' energy choices and consumption patterns to establish local, regional and global trends. Our...
This chapter presents the influence of households’ demographics on food waste generation. A mixed method research approach consisting of meta-analysis, survey (structured interviews), and experimental were used to collect opinions and weigh the amount of waste generated in each household. Although not all demographic variables were investigated, th...
This paper presents the environmental health risks associated with indiscriminate dumping of solid waste in Lekwa Local Municipality. Structured observations were used to collect data from the identified waste dumping spots. The primary data collected involved the characterization of waste streams, estimation of distances between dumping spots, wat...
This paper presents the extent to which kitchen structures influence household exposure to firewood-induced volatile organic compounds (VOCs). The sample consisted of 69 firewood users who were conveniently sampled from Senwabarwana Villages. An Integrated Environmental Health Risk Assessment framework (IEHRA) was adopted as the research methods of...
Nearly 290,000 tons of electronic waste was generated in Nigeria during the year 2017, which is likely to increase further due to high population growth rates, accelerated urbanization, high demand for electronic products, as well as disposal at their end-of-life. At the same time, e-waste is associated with negative human health impacts, as well a...
This paper presents the factors that influence firewood use among electrified Bapedi households in Senwabarwana Villages. The study follows explanatory and exploratory methods of data analysis, through survey (structured interviews) and meta-analysis. In-depth content analysis was followed to establish trends and identify factors that influence the...
This paper reviews the influence of municipal sustainable chain management on South Africa’s recycling performance. In this study, municipal supply chain management systems are identified as one of the major factors that influence the lack of municipal solid waste services in communities (including recycling performance in South Africa). Through an...
This article presents the association between energy saving in guesthouses and guest comfort. The study was conducted in the Mpumalanga Province, one of the nine provinces of South Africa and a leading tourism destination. The focus was to determine the relationship between energy reduction and its impact on the quality of services in selected gues...
One of the major hidden secrets about recycling success is understanding the pull and push factors that influence recycling performance. A myriad of studies have explored several factors according to their circumstances and professional interests. However, not much has been done to examine the influence of government procurement systems on recyclin...
Indigenous South African (SA) communities (former homelands) have no access to municipal refuse collection. These communities use indigenous knowledge for refuse disposal. Unfortunately, in SA indigenous practices are:
1. Not documented
2. Not recognized by government
3. Not as a formal system of services delivery
4. Not funded through public fun...
A number of households in South Africa use indigenous systems to dispose their waste, because they have no access to municipal services.
A recent study identified a mixed stream of waste in Badplaas, Carolina and Elukwatini landfills. However, the risks associated with the situation in the three selected towns remains unknown. Thus, this paper fills this gap of qualitatively assessing the potential environmental health risks associated with specific waste streams identified. Secondl...
This study presents a characterization framework for energy efficient hotels. It builds on existing frameworks of energy efficiency and the adopted characterization framework advances from the input-output framework. The theoretical framework was developed through an in-depth literature analysis. In contrast with other frameworks, this framework in...
This paper presents an energy characterisation framework that is based on environmental and carbon management accounting principles and practices that promote green growth in societies. Primary data was collected through survey questionnaires, observation checklists, energy account records, light meters and thermometers. In addition, an exploratory...
Meat is highly nutritional and rich in proteins, which makes it a good substrate for possible microbial growth. As a result, in its raw state, meat is easily susceptible to colonization by microorganisms. This study describes the possible sources of contamination associated with food handlers in butcheries, as well as the microorganisms that are ab...
Most developing countries grapple with management of solid waste and environmental health risks associated with insanitary conditions. Indiscriminate dumping of household and industrial waste remains an alternative means of waste disposal for communities that have no access to reliable refuse removal services. This phenomenon affects not only devel...
Household energy consumption, transport and waste disposal contribute 51.2%, 32.8% and 16% of anthropogenic carbon to the atmosphere, respectively. Although most of the waste based carbon is convertible into various forms of energy for households and transport needs, much of the available technologies are not sufficiently used in South Africa. Thus...
This article presents the association between energy saving in guesthouses and guest comfort. The study was conducted in the Mpumalanga Province, one of the nine provinces of South Africa and a leading tourism destination. The focus was to determine the relationship between energy reduction and its impact on the quality of services in selected gues...
The characterisation of unregulated landfills as general landfills is misleading particularly because these landfills are used to dispose of a mixed stream of general and hazardous waste. Unregulated landfills are unlicensed on-land waste disposal facilities that are not designed, constructed or operated according to any regulatory framework. These...
This paper presents the results of an investigation undertaken on the influence of energy saving on the quality of lighting services on selected hotels in Mpumalanga, one of the nine provinces of the Republic of South Africa. This paper adopted a multiple case study methodology in which eight hotels were selected for in-depth study. Questionnaires,...
The number of South African hotels has doubled between 1997 and 2004. Literature shows that an increase in hotel numbers is proportional to economic growth and energy demand, respectively. This is evident from a study in Greece. The life cycle of a hotel depends entirely on energy availability. Hence, studies show that energy costs in hotels are th...
The increase in the number of guest houses is applausive for its socio-economic benefits through income generation, job creation and entrepreneurship growth. However, the increase in the number of guest houses is proportional to energy demand. Thus, increase in energy efficient guest houses is more desirable in order to achieve sustainable developm...
