    • Preparation of polyurethane from lignin and crude glycerol 

      Muller, L.C.; Marx, S.; Chiyanzu, I.; Vosloo, H. (ETA-Florence Renewable Energies, 2015)
      Polyurethane foam (PUF) was prepared by a novel approach, using a renewable polyol derived from only biofuel production by-products, lignin and crude glycerol. This could potentially be a high value bio-refinery application ...
    • 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 ...
