Humins is a biomass-derived material, co-product of the acid-catalyzed conversion of cellulose and hemicellulose to platform chemicals. This work presents a thorough study concerning the crosslinking kinetics of humins by chemorheological analysis and model-free kinetics under isothermal and non-isothermal curing. Humins can auto-crosslink...
Several equations have been compared for the modelling of semi-cristalline polymer crystallization on cooling from the melt and on heating from the glass. The temperature dependence was described with the Hoffman–Lauritzen (HL) equation, where U* and Kg were first determined by fitting the activation energy (Eα) dependency with temperature...

Poly(ethylene 2,5-furandicarboxylate)(PEF), an emerging biobased polyester, was compounded with cellulose via twin-screw extrusion. Different extrusion parameters such as mixing time, screw speed and temperature were employed. Composite thin films containing 1, 2 and 4% cellulose w/w were prepared and compared with neat PEF films. The...

Industrial humins from biorefining process of sugars were used as reactive thermoset matrix for the preparation of humins-jute fibre composites. This material was investigated and benchmarked with jute composites prepared with polyfurfurylalcohol (PFA), a well-known biobased thermosetting resin The Dynamic Mechanical Analyses (DMA) showed glass...

The concept of circular economy is aiming at promoting innovative use of wastes, residues, or byproducts into marketable chemicals and intermediates, while enhancing process economics and environmental sustainability. Within biorefineries, the focus has now shifted toward "humins", polymeric condensation byproducts far less investigated than...
