Bio-catalytic upgrading of phenolic components present in waste water of a hydrothermal liquefaction plant
Chimbazaza, Edson (North-West University (South Africa)., 2021)Vanillyl alcohol oxidase is a flavoenzyme naturally sourced from Penicillium simplicissimum. It is a potential candidate in the commercial production of vanillin, an expensive natural flavourant in the cosmetic, food, ... -
Biodiesel production from plant oils of African origin
Chilabade, D. (North-West University, 2018)As the search for alternative sources of energy to supplement traditional fossil-derived energy has intensified across the globe, biodiesel derived from biolipids has emerged as a promising alternative to diesel fuel. This ... -
Characterization of lignosulphonate and its changes during purification
Naude, Leané (North-West University (South Africa)., 2023)The world needs an environmentally friendly renewable resource that could satisfy future energy needs and lower the impact on climate change. This need has driven many countries to fund research into biomass and biomass ... -
The effect of cellobiohydrolase I on low consistency refining and handsheet properties
Makubo, Ntokozo Ivory (North-West University (South Africa)., 2022)Papermaking is an energy-intensive process, with mechanical pulp refining accounting for 30% of the total electrical energy consumption during papermaking. Presently, with significant economic and environmental concerns, ... -
The effects of kneading and enzymatic treatments on properties of viscose-grade dissolving wood pulp
Sandham, Devon John (North-West University (South Africa)., 2022)Dissolving wood pulp (DWP) is a high-purity form of cellulose that is produced by pulping and bleaching lignocellulosic biomass to obtain a cellulose content greater than 90%. DWP is used as the feedstock for many applications ... -
Establishing a techno-economic base case for a second generation bio-refinery : a South African perspective
Van Coller, Ruveix Hurter (North-West University (South Africa)., 2023)A baseline techno-economic assessment for converting organic municipal waste via a novel continuous hydrothermal liquefaction (cHTL) pilot plant is presented. Feed streams, product yields, and product quality were based ... -
In-situ biodiesel production using liquefaction and supercritical extraction
De la Rey, J.H. (North-West University (South Africa), 2016)Biodiesel is an alternative source of energy with the potential to replace diesel fossil fuel. Full scale production however, has been hampered by high production costs since the extraction of oil causes excessive losses ... -
Modification of dissolving wood pulp using endoglucanase
Reichel, C. (North-West University (South Africa), 2021)Dissolving wood pulp, a final product of the pulping and bleaching processes, with a cellulose content greater than 90%, has many applications. Each application requires specific properties of the dissolving wood pulp and ... -
A South African perspective investigatingfive nitrogen application levels for optimumsweet sorghum juice yields needed for theproduction of bio-ethanol
Snijman, J.L. (North-West University (South Africa), 2020)The rasionale behind this study was merely to determine whether the tested sweet sorghum genotypes can be utilised as a renewable bio-ethanol resourse and whether different nitrogen (N) application levels have an effect ... -
Wastewater remediation using municipal solid waste-derived hydrochar
Dewah, ChristineTambudzai (North-West University (South Africa)., 2023)Industrialisation and population growth increase solid waste generation and the release of toxic pollutants into the environment. Therefore, novel approaches are necessary for both wastewater remediation and solid waste ...
