Degradation of glyphosate using environmental lignocellulolytic fungal isolates and extracellular enzymes
(North-West University (South Africa), 2023)Glyphosate is the most used herbicide in the world. Having been detected in food and water systems, glyphosate raises several concerns around food safety and its environmental impact. Recent studies have found an increase ... -
Influence of extraction methods on antimicrobial activities of lignin-based materials: a review
(Elsevier, 2020)Lignin is an abundant biomass-derived polymer that can be utilized as an antimicrobial agent. However, its antimicrobial properties depend on the method used for its extraction. Amongst the extracted lignin, lignin-based ... -
Polyol preparation by liquefaction of technical lignins in crude glycerol
(Scrivener Publishing, 2017)This work reports a study of polyol synthesis through liquefaction of technical lignins in crude glycerol by means of 1H and 31P NMR spectroscopy. The polyols are intended for preparation of polyurethane foam; thus, it is ... -

Preparation of polyurethane foam from lignin and crude glycerol
(North-West University (South Africa), Potchefstroom Campus, 2018)The development and implementation of lignocellulose-based biorefineries which produce renewable fuels, chemicals and pharmaceuticals are expected to grow, but still face technological challenges. Economic feasibility could ... -
Production of bio-degradable polyurethane foam from sugarcane bagasse and biodiesel-derived crude glycerine
(ETA-Florence Renewable Energies, 2015)As the threat of the depletion of fossil based fuels becomes more of a reality, there is a need to find alternative carbon sources for the production of a wide range of chemicals, polymers and plastics. One plastic that ... -
Separation of lignin from industrial prehydrolysis liquor using a solid acid catalyst
(ETA-Florence Renewable Energies, 2019)The concept of a biorefinery has been introduced in the pulp and paper industry in order to improve the industry’s profitability and competitiveness by generating new revenues from new products. Prehydrolysis liquor (PHL) ... -
Valorisation of waste lignin for phenol derivative compounds using hydrothermal liquefaction
(EUBCE, 2019)Approximately 95% of global phenolic compounds (such as catechol, guaiacol, syringol, and vanillin) used in the pharmaceutical, fragrance and industrial industries are produced from petroleum-based phenolics such as benzene. ...
