Assessing the financial viability of renewable independent power production in South Africa
(2014)The cost of energy and national power utility Eskom, is currently under heated debate after the cost of electricity has more than doubled over the past three years, with another five annual increases of 8% approved by the ... -
Chemical and physical characterization of spent coffee ground biochar treated by a wet oxidation method for the production of a coke substitute
(Elsevier, 2020)Coke production relies on the availability, cost and quality of coking coal. Depleting coking coal resources and environmental pressure force the metallurgical industry to search for alternative methods to produce coke. ... -
Co-pyrolysis of coal and raw/torrefied biomass: a review on chemistry, kinetics and implementation
(Elsevier, 2021)Thermochemical conversion via co-pyrolysis has the potential to be an efficient route for converting biomass to bio-energy and bio-refinery products. In this review, the implementation of co-pyrolysis of torrefied biomass ... -
Co-pyrolysis of torrefied biomass and coal : product evaluation and reaction modelling
(North-West University (South Africa)., 2022)The co-utilization of biomass and coal in existing coal-based conversion technologies has received increasing interest for its ability to reduce the dependence on fossil fuels and produce high quality products. However, ... -
A comparison of selected enhanced (coated) and non-enhanced grass seed types for re-seeding of disturbed areas
(North-West University, 2007)Restoration and rehabilitation activities are presently considered to be a major priority in environmental management, whether the activity implies the restoration of neglected cultivated pastures or degraded rangelands ... -
Composition and diversity of Mopaneveld herbaceous vegetation : an exclosure experiment
(North-West University (South Africa), Potchefstroom Campus, 2015)The herbaceous vegetation layer of the semi-arid Mopaneveld savanna possess a distinctive homogeneity and is highly dynamic in its response to disturbances such as herbivory. Understanding how this ecosystem reacts to ... -
The cultivation and harvesting of micro–algal biomass from the Hartbeespoort Dam for the production of biodiesel
(North-West University, 2011)Renewable energy sources such as biomass are becoming more and more important as alternative to fossil fuels. One of the most exciting new sources of biomass is micro-algae. The Hartbeespoort Dam, located 37 km west of ... -
An econometric analysis of energy poverty and sustainable development in Blantyre (Malawi)
(North-West University, 2013)Energy is the driver of activity in every economy and, therefore, its importance cannot be overemphasised. However, Sub-Saharan Africa (SSA) faces general problems of access to modern energy. Most households and industry ... -
Effect of biomass feedstock composition on biochar properties produced through hydrothermal liquefaction
(EARET, 2018)The effect that 6 different biomass feedstocks have on biochar was investigated. The biochar was produced through hydrothermal liquefaction at temperatures of 260˚C and 300˚C. The effect of temperature was also investigated. ... -
Effect of different plant substrates and growth hormones on the development characteristics and nutrient content of Pleurotus ostreatus in semi-arid conditions
(North-West University (South Africa), Mafikeng Campus, 2017)With the global and local need to identify low-cost sustainable sources of protein and essential minerals for human nutrition the study was undertaken to investigate effect of different plant growth substrates and hormones ...
