The advancement of the waste resource optimization and scenario evaluation model: the inclusion of socio-economic and instituitonal indicator.
(2018)This study explored Novice Teacher Educators (NTEs) experiences of Relational Learning in a private Higher Education Institution (HEI) in South Africa. The main purpose of this study was to gain a deeper understanding ... -
Anaerobic digestion of energy crop (cassava)
(2019)Global energy demand is on the rise due to continuous increases in population, economic growth, and energy usage. Methane production through anaerobic digestion of organic materials provides a resourceful carrier of ... -
The applicability of C&D waste material in South Africa road construction.
(2015)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
An assessment of carbon emissions reduction potential through zero waste activities in South African municipalities.
(2010)The inception of global warming has resulted in mitigation efforts across all relevant sectors. Waste management activities produce approximately 12% of methane emissions in South Africa. The current scope of waste ... -
Assessment of permeable reactive barriers alternative media for the remediation of nitrate-contaminated ground-waters.
(2013)The increase in the contamination of ground-water (GW) with nitrates in both developing and developed countries mainly results from agricultural activities and improper sanitation systems, and is a recent phenomenon that ... -
Building a framework for the sustainable African city of the future.
(2021)The increase in rural to urban migration rates have resulted in the rapid urbanization and uncontrolled growth of modern day cities. This trend is expected to continue in the coming years, thereby increasing the demand for ... -
Characterisation and management of landfill emissions under a sub- tropical climate using full-scale landfill cells.
(2002)It is now widely understood that landfills, compnslng municipal solid wastes, typically undergo biological degradation processes in what are referred to as Bio-Reactor Landfills. These microbiological processes cause the ... -
Circular economy design visioning: exploring industrial and urban symbiosis in South African cities.
(2017)Cities of tomorrow will be at the coalface of the complex challenges posed by climate change, e.g. resource scarcity. Climate change adaptation strategies will include circular economy (CE) practices (e.g. industrial and ... -
A comparative analysis of waste to energy scenarios to achieve sustainable smart mobility in the Durban Aerotropolis.
(2021)The aim of this dissertation was to develop a multi-criteria decision making tool which could assist Transport Engineers at the eThekwini Municipality to decide which bus propulsion technology to select for Line C8 of the ... -
Denitrification of high strength landfill leachate using garden refuse compost and pine bark.
(2009)Landfill leachate, a toxic by-product formed through the decomposition of organic matter, is harmful to the environment and human health. After nitrification, the concentration of nitrate in discharged leachate may still ... -
Denitrification of high strength nitrified landfill leachate using raw and lightly composted commercial garden refuse (CGR) as carbon sources.
(2011)Waste is commonly disposed in landfills, this result in the formation of leachate which needs to be treated to acceptable standards before being discharged to the environment. High concentrations of pollutants, particularly ... -
Denitrification of leachate using domestic waste at different levels of stability : simulations in batch test.
(2011)Disposing of waste on land has been a method practiced by many countries because it is relatively inexpensive. This has led to the fast increase of landfilling option which is also due to increase of waste generation, ... -
Development of an integrated model for urban sustainable resilience through smart city projects in the Southern African context.
(2021)The construct Smart City has gone through a few phases in the last decades. Today there is still no consensus on an accurate definition of Smart City, even though a few concepts are now accepted by most stakeholders, ... -
An economic comparison of the waste management schemes employed in Cape Town and Johannesburg.
(2006)The disposal of waste into landfill sites is currently the most commonly employed method of dealing with waste in South Africa as well as internationally. However the global trend towards operating waste management systems ... -
The efficacy of using the microalgae chlorella sp. for the treatment of hazardous landfill leachate.
(2015)Abstract available in PDF file. -

(2011-01-14)Storm water runoff is a leading cause of degradation in the water quality of receiving water bodies. Although legislation requires that Environmental Impact Assessments (EIA) are performed and Environmental Management ... -
Environmental management strategy : Krantzkloof Nature Reserve, a case study.
(2006)KZN Nature Conservation Services budgetary cuts for the KrantzkloofNature Reserve (KNR) has led to economic shortfalls in important areas like facilities maintenance and invader plant control. The study has found that the ... -
Further development of WROSE, decision-making tool for KZN municipalities.
(2016)Abstract available in PDF file. -
Garden refuse composting as part of an integrated zero waste strategy for South African municipalities.
(2010)Garden refuse has been seen to constitute a significant proportion of the total waste stream received at landfills in the eThekwini Municipal Area (EMA). With the growing demand for conserving “precious landfill airspace” ... -
The impacts of climate change in relation to plastic waste on the Umgeni River system.
(2021)The use of plastics and plastic by-products have become so profusely common in everyday life of society that the issues attached to its recycling, disposal and preventing contamination to our soils, rivers and oceans have ...
