Antioxidant, Antifungal and Phytochemical Investigations of Capparis spinosa L.
(MDPI, 2021-10-19)
The antioxidant and antifungal activities of crude hydro-ethanolic extract from Capparis spinosa L. (Capparidaceae) leaves and their fractions, obtained by liquid-liquid extraction (LLE) using solvents with increasing ...
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 ...
Eco-friendly isolation and characterization of nanochitin from different origins by microwave irradiation: optimization using response surface methodology
(Elsevier, 2021-07-09)
[EN] The extraction of nanochitin from marine waste has attracted great industrial interest due to its unique properties,
namely biodegradability, biocompatibility and as a functional reinforcing agent. Conventional acid ...
Optimization of Ultrasound Assisted Extraction of Bioactive Compounds from Apple Pomace
(MDPI, 2021-06-22)
In the present work, the optimization of the extraction of antioxidant compounds from apple pomace using ultrasound technology as an environmentally friendly and intensification process was developed. Different sonication ...
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, ...
Direct lignin depolymerization process from sulfur-free black liquors
(Elsevier, 2019-09-03)
Agricultural residues (olive tree pruning and almond shell) were subjected to different delignification treatments (organosolv and soda) and the obtained liquors were treated in a high-pressure reactor at 300 °C for 80 min ...
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 ...
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 ...
Study of a renewable capping agent addition in lignin base catalysed depolymerisation process
(Elsevier, 2020-07-13)
The aim of this work was to study the influence of a renewable capping agent (CA) in the production of monomeric compounds from the depolymerization of an organosolv lignin (Pinus radiata) by a base catalyzed depolymerization ...
