Lignin-ester derivatives as novel thermoplastic materials
(RSC, 2016)
[EN] Spruce and eucalyptus lignins isolated by an organosolv process and lauroyl chloride were used as raw material for the synthesis of lignin-ester derivatives. The obtained products presented new and interesting properties ...
Renewable biopolyols from residual aqueous phase resulting after lignin precipitation
(ACS, 2021-02-19)
The aim of this work was to obtain two biopolyols from the liquid residue resulting from the precipitation of lignin contained in two different black liquors, Eucalyptus globulus organosolv black liquor (EOBL) and Pinus ...
Multistage treatment of almonds waste biomass: characterization and assessment of the potential applications of raw material and products
(Elsevier, 2018-09-06)
Almond shells are waste biomass generated in agro-industrial activities, which represent a resource that can be further valorized upon treatment. The purpose of this work was to assess new value-added products obtained ...
Modification of Eucalyptus and Spruce organosolv lignins with fatty acids to use as filler in PLA
(2016-05-09)
Spruce (softwood) and Eucalyptus (hardwood) woods were used as raw material for lignin extraction by
organosolv process. Chemical, structural and thermal characterizations of the extracted lignin samples have
been performed ...
Multiproduct biorefinery based on almond shells: impact of the delignification stage on the manufacture of valuable products
(Elsevier, 2020-07-22)
In this work, an integral valorisation of almond shells through a biorefinery approach was studied. The three main components of almond shells were extracted, isolated and characterised. The autohydrolysis process permitted ...
Techno-economic analysis of different integrated biorefinery scenarios using lignocellulosic waste streams as source for phenolic alcohols production
(Elsevier, 2021-02)
The whole process of lignin extraction from a lignocellulosic waste streams (almond shell) by sulfur-free methods and its depolymerization by base catalyzed or solvolysis reactions have been addressed in this work. In ...
Lignin oxidation and depolymerisation in ionic liquids
(RSC, 2015-09)
The depolymerisation of lignin directly in the black liquor was studied, comparing two ionic liquids as extracting solvents (butylimidazolium hydrogen sulphate and triethylammonium hydrogen sulphate), under oxidising ...
Liquefaction of Kraft lignin using polyhydric alcohols and organic acids as catalysts for sustainable polyols production
(Elsevier, 2019)
[EN]In this work, three different organic acid catalysts, (acetic acid, lactic acid and citric acid), are proposed as an
alternative to common catalysts used in the liquefaction process of Kraft lignin. These organic acids ...
Kraft lignin as filler in PLA to improve ductility and thermal properties
(Elsevier, 2015-10)
[EN] Kraft lignin (KL) and acetylated Kraft lignin (AKL) were used as filler for the elaboration of composites
with poly(lactic acid) (PLA) in different concentrations (0.5, 1, 5, 10 and 20%) by extrusion method at
200 ...
Hydrothermal treatments of walnut shells: a potential pretreatment for subsequent product obtaining
(Elsevier, 2020-10-08)
Walnuts are nowadays widely consumed. Since the edible part of walnuts does not account more than 50-60% of their total weight, the total amount of shells produced annually is huge. However, as walnut shells are part of ...
