The quality of education is significantly influenced by occupational health and safety (OHS) measures. To this end, a safety incident at a university could have far-reaching negative effects on facilitating teaching and learning for both lecturers and students. Although OHS standards are widely established in numerous industries, they are often overlooked in the academic setting. It is for this reason that, to date, research gap exists in OHS systems in academic settings. While universities primarily focus on education, they also pose significant health and safety risks to staff and students due to their design and setup. Effective implementation of an occupational health and safety management system (OHSMS) within universities can mitigate these risks. However, there is a notable lack of research focusing on the efficiency of OHSMS in South African universities. This study, therefore, aimed to fill this gap by assessing the efficiency of the OHSMS at a South African university. Data were collected using in-depth interviews, observations, and document analysis qualitative research methods. Data analysis was carried out using the thematic analysis approach. Inductive logic was used in the interpretation of the current study results. This study highlights that while there is strong awareness of the OHS Act 85 of 1993 (>90%) among university staff, significant gaps exist in the communication and enforcement (5%) of OHS policy, alongside the poor communication of hazards and risks (30%). Amongst other challenges are infrastructure maintenance (>35%), as well as the lack of standard operation procedures (>5%). To address some of these setbacks, the current study recommends enhancing policy communication, conducting regular hazard assessments, increasing training participation, and improving documentation practices. These steps aim to improve the efficiency and effectiveness of the university’s OHSMS, ensuring a safer environment for all stakeholders.

Solid waste disposal methods within indigenous communities present unique challenges and opportunities for sustainable development. However, the current knowledge on solid waste management focuses on formal waste collection systems, neglecting the practices and sustainability aspects of solid waste management in indigenous communities. Thus, it becomes imperative to undertake research studies that evaluate the sustainability of these practices as they play a pivotal role in ensuring sustainable development. The current study systematically evaluates the views and judgments associated with the sustainability aspects of indigenous waste management practices in the rural communities of South Africa using the Analytic Hierarchy Process (AHP) model. The data analysis was carried out using the AHP model. The findings of this study showed that the rural communities of Bushbuckridge Local Municipality prioritize the sustainability of the environment (weight: 0.590) over the economic (weight: 0.240) and social sustainability (weight: 0.165) based on the AHP evaluative framework. The validity of the priorities was tested through the computed degree of consistency ( 50%, waste trading proved to be of economic efficacy. Using the AHP model to evaluate the sustainability aspects associated with indigenous solid waste management practices addresses a substantial gap in the comprehension of the role of indigenous knowledge towards sustainability in the discipline of solid waste management. However, it also offers a valuable sustainability perception that is associated with indigenous waste disposal methods that local governments and policymakers should include for consideration in integrated waste management plans. This can lead to the development of waste disposal programs that are well-coordinated and in accordance with indigenous sustainable waste management practices that advance the circular economy and promote environmental protection.

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 scarcely documented in the scientific literature despite their position as potential alternative disposal methods. This gap persists amid limited municipal budgets, inadequate waste collection services, and poor infrastructure in economically marginalized indigenous rural communities in developing nations. Subsequently, in the discipline of solid waste management, this obstacle impedes the recognition and inclusion of indigenous waste management practices into integrated waste management plans. As a result, this causes a delay in their progress or elevation to the same level of credibility as mainstream scientific knowledge. In the process, this relegates the waste management practices of indigenous communities to the background. Against this background, the current study sought to investigate the indigenous solid waste management practices of rural communities in Bushbuckridge Local Municipality. As such, ten cases that captured the spatial cultural diversity of indigenous communities’ practices across Bushbuckridge Local Municipality (BLM) were selected for sampling. Data were collected using ethnographic research methods. Data analysis was carried out using the thematic analysis approach. Inductive logic was used in the interpretation of the current study results. The results of the current study indicate that indigenous communities of Bushbuckridge Local Municipality, in the absence of formal waste management services from the local authority, resort to an indigenous knowledge system to manage solid waste. Waste burning (100%), open-air dumping (100%), and backyard pits (90%) are some of the indigenous waste management practices espoused by the rural communities of BLM. The similarity in practices was corroborated by statistical inferences that revealed that between BLM communities, the amount of indigenous waste management practices is not significant (p > 0.05). However, there are concerns that despite the sustainability aspect associated with recycling (<25%) practices, these disposal methods are not common in the rural communities of BLM. This is a setback for an indigenous knowledge system that is supposed to advance environmental sustainability practices.

Indigenous communities have always used their knowledge systems to improve their quality of life. For example, rural communities’ resort to indigenous cultural practices to manage their own waste when local administration lacks coordinated ways to manage waste. In the context of indigenous knowledge systems, the idea of waste is non-existent. As indigenous knowledge is believed to provide a holistic framework for an approach that effectively promotes sustainability. As such, the current study conducted a systematic review to evaluate the extent to which indigenous solid waste management practices contribute to sustainable waste disposal methods. Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, a literature search was carried out in the field of indigenous solid waste management practices. The results indicate a significant imbalance in the amount of conclusive evidence that has been produced to date that suggests the sustainability of indigenous solid waste management practices. It is for this reason that the current study has discovered a substantial literature gap in sustainable solid waste management associated with indigenous knowledge systems. This is an unprecedented trend, especially for a knowledge system that is supposed to promote sustainability practices. However, to improve the likelihood of incorporating indigenous solid waste disposal methods into modern practices, it is imperative to understand the foundational elements that contribute to the advancement of sustainability, lest the sustainability aspect associated with this knowledge system in the discipline of solid waste management remain a mere rhetoric.

This study aimed to analyse the variation of recreational water quality in Plettenberg Bay in an attempt to comprehend the effects of pollution on the environment, and more specifically the potential impacts on the quality of surface water used for recreational activities. Plettenberg Bay is a major destination for tourists in South Africa, with recreational water activities representing an important attraction. For this study, data were obtained from Bitou Municipality, the local au-thority in charge of the water monitoring program in Plettenberg Bay. The selected datasets contained water quality data collected by the Bitou Municipality waterworks department in three sampling sites in Plettenberg Bay. The samples were tested for six water quality parameters namely, Ammonia, Suspended Solids, Conductivity, Nitrates/Nitrites, pH, and E coli. Water quality trends appeared stabile over the five years, with only a few parameters showing variation in their concentration levels. It is recommended that the Bitou Municipality increase the sampling frequency to allow a clearer understanding of water quality variation and to minimise potential uncertainties.

There exists no single optimal way for transporting hydrogen and other hydrogen carriers from one port to the other globally. Its delivery depends on several factors such as the quantity, distance, economics, and the availability of the required infrastructure for its transportation. Europe has a strategy to invest in the production of green hydrogen in Africa to meet its needs. This study assessed the economic viability of shipping liquefied hydrogen (LH₂) and hydrogen carriers to Germany from six African countries that have been identified as countries with great potential in the production of hydrogen. The results obtained suggest that the shipping of LH₂ to Europe (Germany) will cost between 0.47 and 1.55 USD/kg H₂ depending on the distance of travel for the ship. Similarly, the transportation of hydrogen carriers could range from 0.19 to 0.55 USD/kg H₂ for ammonia, 0.25 to 0.77 USD/kg H₂ for LNG, 0.24 to 0.73 USD/kg H₂ for methanol, and 0.43 to 1.28 USD/kg H₂ for liquid organic hydrogen carriers (LOHCs). Ammonia was found to be the ideal hydrogen carrier since it recorded the least transportation cost. A sensitivity analysis conducted indicates that an increase in the economic life by 5 years could averagely decrease the cost of LNG by some 13.9%, NH₃ by 13.2%, methanol by 7.9%, LOHC by 8.03%, and LH₂ by 12.41% under a constant distance of 6470 nautical miles. The study concludes with a suggestion that if both foreign and local participation in the development of the hydrogen market is increased in Africa, the continent could supply LH₂ and other hydrogen carriers to Europe at a cheaper price using clean fuel.

Since food waste is a contemporary and complicated issue that is widely debated across many societal areas, the world community has designated the reduction of food waste as a crucial aspect of establishing a sustainable economy. However, waste management has numerous challenges, such as inadequate funding, poor waste treatment infrastructure, technological limitations, limited public awareness of proper sanitary practices, and inadequate legal and regulatory frameworks. A variety of microorganisms participate in the process of anaerobic digestion, which can be used to convert organic waste into biogas (e.g., methane) and nutrient-rich digestate. In this study, we propose a synergy among multiple disciplines such as nanotechnology, omics, artificial intelligence, and bioengineering that leverage anaerobic digestion processes to optimize the use of current scientific and technological knowledge in addressing global food waste challenges. The integration of these fields carries with it a vast amount of potential for improved waste management. In addition, we highlighted the relevance, importance, and applicability of numerous biogas-generating technologies accessible in each discipline, as well as assessing the impact of the COVID-19 epidemic on waste production and management systems. We identify diverse solutions that acknowledge the necessity for integration aimed at drawing expertise from broad interdisciplinary research to address food waste management challenges.
