An analysis of the potential impact of carbon emission tax on unemployment in South Africa
(North-West University (South Africa), 2019)This study sought to investigate the impact of carbon emission tax on unemployment in South Africa. This particular focus of the study comes at a time when the South African unemployment rate is at a staggering 27.5% ... -
A critical evaluation of the environmental law framework applicable to carbon capture and storage in South Africa
(2013)The objective of this study is to conduct a critical evaluation of the environmental law framework applicable to carbon capture and storage (hereafter CCS) in South Africa. The discussion begins by confirming that CCS has ... -
Development and evaluation of an R–744 evaporator model
(North-West University, 2013)In recent years carbon dioxide (CO2, R-744) has moved to the foreground as an environmentally friendly alternative to commonly used CFCs and HFCs, which are being phased out due to its high ozone depleting and global warming ... -
Evaluating the feasibility of a carbon reducing project : a case study in the mining industry
(2013)Today, global warming is commonly known due to the major impact on the earth’s weather conditions. The increase in the average temperature of the lower atmosphere is causing a drastic change in weather conditions. Human ... -
Evaluation of the gasification reactivity of Highveld coals for application in the coal to liquids process
(North-West University (South Africa) , Potchefstroom Campus, 2017)Coal is a very heterogeneous substance with widely varying properties from one source to another, requiring continuous analysis to determine the properties and reaction behaviour of coals as new sources become mined. There ... -
The impact of carbon taxation on the triple bottom line of the South African motor vehicle manufacturing industry
(2014)Climate change has become an important concern for most governments in the current day. The impact of global warming on economic productivity, human welfare and environmental sustainability is becoming increasingly apparent ... -
The potential utilization of nuclear hydrogen for synthetic fuels production at a coal–to–liquid facility
(North-West University, 2010)The production of synthetic fuels (synfuels) in coal–to–liquids (CTL) facilities has contributed to global warming due to the huge CO2 emissions of the process. This corresponds to inefficient carbon conversion, a problem ... -
Supercritical fluid extraction of Sclerocarya birrea kernel oil
(2015)Sub-Saharan Africa is a treasure chest of natural materials remaining to be explored for commercial applications and as alternative foods to diversify and improve food sustainability. The Marula tree is available in abundance ... -
The use of hydrogen as a reductant in the smelting industry
(North-West University (South Africa), 2022)Both the smelting of chromite and manganese (Mn) ores consume a significant amount of carbon (C) and electrical energy. The smelting processes contribute to the elevation of carbon dioxide (CO2) emissions in the atmosphere ...
