Integral valorisation of walnut shells based on a three-step sequential delignification
(Elsevier, 2022-05)
[EN] Walnut kernels represent no more than 50-60% of the total weight of the fruit, so the sum of walnut shells generated every year is immense. Nonetheless, these shells could be further valorised for the extraction of ...
Recovery of Bioactive Compounds from Hazelnuts and Walnuts Shells: Quantitative–Qualitative Analysis and Chromatographic Purification
(MDPI, 2020-09-24)
Hazelnut (HS) and walnut (WS) shells, an abundant by-product of the processing industries of these edible nuts, are traditionally considered as a low-value waste. However, they are a source of valuable compounds with an ...
Thermochemical and Mechanical Properties of Pine Wood Treated by In Situ Polymerization of Methyl Methacrylate (MMA)
(MDPI, 2020-07-17)
The impregnation of low-molecular-weight monomers prior to polymerize them inside the wood may be an efficient way to improve some important wood properties. This work aimed to determine some technological properties of ...
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 ...
Energy and environmental analysis of flavonoids extraction from bark using alternative solvents
(Elsevier, 2021-05-04)
[EN] Tree barks are rich in extractive compounds, among which the flavonoids are considered as products of interest. Due to the increase in the demand for these natural products, the development of efficient and sustainable ...
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 the extraction of galactoglucomannans from Pinus halepensis
(About De Gruyter, 2021-06-25)
The effectiveness of pressurized hot-water extraction conditions for obtaining galactoglucomannans (GGMs) from Pinus halepensis suitable for applications like coatings and films packaging was investigated. For this purpose, ...
Evaluation of Bioactive Release Kinetics from Crosslinked Chitosan Films with Aloe Vera
(Elsevier, 2021-07-01)
Thermocompression was employed to prepare citric acid-crosslinked chitosan films with Aloe vera (AV) as bioactive compound. Films were easy to handle and mechanical properties did not change with the addition of AV up to ...
Multiple Intelligence Informed Resources for Addressing Sustainable Development Goals in Management Engineering
(MDPI, 2022)
The competence-based model focuses on acquiring skills and abilities, yet each student’s individual circumstances condition the way in which they learn, develop, and implement them. Accordingly, there is a growing interest ...
One-Step Lignin Refining Process: The Influence of the Solvent Nature on the Properties and Quality of Fractions
(MDPI, 2022)
Heterogeneity of kraft lignin is one of the main limitations for the development of high-performance applications. Therefore, refining lignin using organic solvents is a promising strategy to obtain homogenous fractions ...
