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 ...
Sustainable Sheep Wool/Soy Protein Biocomposites for Sound Absorption
(MDPI, 2022-12-01)
The wool fibers of the Latxa sheep breed were combined with a soy protein isolate (SPI)
matrix to develop sustainable biocomposites with acoustic properties, adding value to Latxa sheep
wool, which is currently considered ...
New algorithm for the elucidation of functional properties of gelatin-based materials
(Pergamon-Elsevier, 2021-10)
In the present work, fish gelatin was employed to develop renewable and biodegradable materials, reducing environmental problems associated with conventional petroleum-based materials. Glycerol was used as plasticizer and ...
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 ...
Galernas: A history of coastally trapped disturbances (2003−2020) with hidden frontogenesis in the Bay of Biscay
(Elsevier, 2023-01)
Galerna is the term accepted for an abrupt westerly change that affects the north coast of Spain. The wind surge travels from the mid-north coast of Spain to France, generally reaching their maximum intensity at the Basque ...
Assessment of Biomass Energy Potential and Forest Carbon Stocks in Biscay (Spain)
(MDPI, 2016-03)
The aim of this research is to identify, quantify and characterize the potential available forest biomass of Pinus radiata D. Don and Eucalyptus globulus Labill. across Biscay province in northern Spain. In order to do ...
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, ...
Closing the loop: Waste valorisation from vegetal sources to develop fruit active films
(Elsevier, 2024-07)
Cellulose-rich residue after agar extraction was incorporated into gelatin film forming formulations in order to revalorize it and improve film properties. This revalorized cellulose was compared with the commercial sodium ...
