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 ...
A Holistic Approach to Integrate and Evaluate Sustainable Development in Higher Education. The Case Study of the University of the Basque Country
(MDPI, 2021-01-04)
Since the United Nations (UN) approved the Agenda 2030 for Sustainable Development in 2015, higher education institutions have increasingly demonstrated their commitment by supporting several initiatives. Although a great ...
Metal Extraction and Recovery from Mobile Phone PCBs by a Combination of Bioleaching and Precipitation Processes
(MDPI, 2021-09-15)
Bearing in mind the metal rich composition of printed circuit boards (PCBs), this material represents a secondary source of valuable metals and offers an entrepreneurial opportunity in the metal sales market. Based on the ...
Kinetic modelling for concentration and toxicity changes during the oxidation of 4-chlorophenol by UV/H2O2
(Nature, 2021-08-03)
This work develops a kinetic model that allow to predict the water toxicity and the main degradation products concentration of aqueous solutions containing 4-chlorophenol oxidised by UV/H2O2. The kinetic model was developed ...
Fe/Olivine As Primary Catalyst in the Biomass Steam Gasification in a Fountain Confined Spouted Bed Reactor
(Elsevier, 2021-07-25)
The performance of Fe/olivine catalysts was tested in the continuous steam gasification of sawdust in a bench scale plant provided with a fountain confined conical spouted bed reactor at 850 degrees C. Olivine was used as ...
Tools for Embedding and Assessing Sustainable Development Goals in Engineering Education
(MDPI, 2021-11-03)
This paper presents three tools developed within the framework of the project EDINSOST2-SDG, aimed at embedding and assessing the Education for Sustainable Development (ESD) in Engineering curricula. ESD is promoted through ...
Characterization of Bio-Inspired Electro-Conductive Soy Protein Films
(MDPI, 2021-01-28)
Protein-based conductive materials are gaining attention as alternative components of electronic devices for value-added applications. In this regard, soy protein isolate (SPI) was processed by extrusion in order to obtain ...
Degradability of Polyurethanes and Their Blends with Polylactide, Chitosan and Starch
(MDPI, 2021-04-08)
One of the methods of making traditional polymers more environmentally friendly is to modify them with natural materials or their biodegradable, synthetic equivalents. It was assumed that blends with polylactide (PLA), ...
Morphology, Thermo-Mechanical Properties and Biodegradibility of PCL/PLA Blends Reactively Compatibilized by Different Organic Peroxides
(MDPI, 2021-07-28)
Reactive blending is a promising approach for the sustainable development of bio-based polymer blends and composites, which currently is gaining more and more attention. In this paper, biodegradable blends based on ...
Residues from rigid foams and graphene for the synthesis of hybrid polyurethane flexible foams composites
(Elsevier, 2021-06)
Hybrid biobased polyurethane flexible foam composites containing a residue from surf industry (polyurethane powder) as filler and graphite or graphene residue were synthe-sized. It was observed that the addition of the ...
