Effect of Deterpenated Origanum majorana L. Essential Oil on the Physicochemical and Biological Properties of Chitosan/β-Chitin Nanofibers Nanocomposite Films
(MDPI, 2021-05-07)
Herein, the effect of three deterpenated fractions from Origanum majorana L. essential oil on the physicochemical, mechanical and biological properties of chitosan/β-chitin nanofibers-based nanocomposite films were ...
Microwave-Assisted Extraction of Curcuma longa L. Oil: Optimization, Chemical Structure and Composition, Antioxidant Activity and Comparison with Conventional Soxhlet Extraction
(MDPI, 2021-03-10)
Curcuma root (Curcuma longa L.) is a very important plant in gastronomy and medicine for its unique antiseptic, anti-inflammatory, antimicrobial and antioxidant properties. Conventional methods for the extraction of curcuma ...
Wood Flour Modified by Poly(furfuryl alcohol) as a Filler in Rigid Polyurethane Foams: Effect on Water Uptake
(MDPI, 2022-12-16)
The use of lignocellulosic fillers in rigid polyurethane foams (RPUFs) has been receiving great attention due to their good mechanical and insulation properties and the high sustainable appeal of the obtained cellular ...
Cross-Linked Carboxymethylcellulose Adsorbtion Membranes from Ziziphus lotus for the Removal of Organic Dye Pollutants
(MDPI, 2022-12-08)
The goal of this study is to assess Ziziphus lotus’s potential for producing carboxymethylcellulose adsorption membranes with the ability to adsorb methyl green from wastewaters by the revalorization of its cellulosic ...
Fractionation of non-timber wood from Atlantic mixed forest into high-value lignocellulosic materials
(Taylor & Francis, 2020-03-10)
[EN] The forestry industry in the Basque Country has experienced an abandonment of small-sized forests in which native and introduced species tend to regrow if unattended; thus, requiring an intervention under which proper ...
Extraction of flavonoid compounds from bark using sustainable deep eutectic solvents
(Elsevier, 2021-12)
[EN] The use of green solvents in extraction processes, especially for applications of lignocellulosic biomass, has been extensively studied over the last years. Among the range of different green solvents, deep eutectic ...
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 ...
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 ...
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 ...
