Fine-tune of lignin properties by its fractionation with a sequential organic solvent extraction
(Elsevier, 2022-01)
[EN] In this work, different lignins were obtained from two different extraction methods (kraft and organosolv) but from the same raw material (Eucalyptus globulus sp.). They were subsequently fractionated to determine the ...
Life Cycle Assessment of various biorefinery approaches for the valorisation of almond shells
(Elsevier, 2021-10)
In the near future, sustainable and efficient biorefineries would be essential for the production of commodity chemicals and high-added value compounds. Therefore, in this work, six scenarios differing on the delignification ...
Optimisation of lignin liquefaction with polyethylene glycol/ glycerol through response surface methodology modelling
(Elsevier, 2023-08)
In order to diminish the dependence on oil lignin, which is the most abundant biopolymer of phenolic origin on Earth and can be utilised in different industrial endeavours, such as, the production of polyurethanes. In this ...
Valorisation of crude glycerol in the production of liquefied lignin bio-polyols for polyurethane formulations
(Elsevier, 2023-08)
Bio-polyols, produced by liquefying lignin with polyhydric alcohols, offer a promising alternative to conventional polyols for polyurethane production. To enhance the sustainability on the production of these bio-polyols, ...
