    • Functionalising lignin in crude glycerol to prepare polyols and polyurethane 

      Muller, Louis Christiaan; Marx, Sanette; Vosloo, Hermanus C.M.; Chiyanzu, Idan (Sage, 2019)
      In this work, crude glycerol liquefaction of lignins produced in the pulp and paper industry, as well as an organosolv lignin (sugarcane bagasse), was studied with the ultimate aim of preparing biobased polyols for ...
    • Preparation of polyurethane foam from lignin and crude glycerol 

      Muller, Louis Christiaan (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 ...
    • Rigid polyurethane foams from unrefined crude glycerol and technical lignins 

      Muller, Louis Christiaan; Marx, Sanette; Vosloo, Hermanus C.M.; Fosso-Kankeu, Elvis; Chiyanzu, Idan (Sage, 2018)
      The need for green materials has driven interest in the preparation of rigid polyurethane foam (PUF) from various biomass types. The present study aims at increasing bio-based content by utilizing by-products from both ...
