Secondary Raw Materials from Residual Carbon Fiber-Reinforced Composites by An Upgraded Pyrolysis Process
(MDPI, 2021-10-04)
This paper presents a process where carbon fibers and hydrogen can be recovered simultaneously through a two-stage thermal treatment of an epoxy-carbon fiber composite. For this purpose, some pieces of epoxy resin reinforced ...
Bio-Based Polyurethane Networks Derived from Liquefied Sawdust
(MDPI, 2021-06-07)
The utilization of forestry waste resources in the production of polyurethane resins is a promising green alternative to the use of unsustainable resources. Liquefaction of wood-based biomass gives polyols with properties ...
Superabsorbent bacterial cellulose spheres biosynthesized from winery by-products as natural carriers for fertilizers
(Elsevier, 2021-11-30)
[EN]Soil contamination, sustainable management of water resources and controlled release of agrochemicals are the main challenges of modern agriculture. In this work, the synthesis of sphere-like bacterial cellulose (BC) ...
3D-Printed Mucoadhesive Collagen Scaffolds as a Local Tetrahydrocurcumin Delivery System
(MDPI, 2021-10-15)
Native collagen doughs were processed using a syringe-based extrusion 3D printer to obtain collagen scaffolds. Before processing, the rheological properties of the doughs were analyzed to determine the optimal 3D printing ...
Effect of the Addition of Alkaline Earth and Lanthanide Metals for the Modification of the Alumina Support in Ni and Ru Catalysts in CO2 Methanation
(MDPI, 2021-03-09)
In order to reduce greenhouse gas emissions, which are reaching alarming levels in the atmosphere, capture, recovery, and transformation of carbon dioxide emitted to methane is considered a potentially profitable process. ...
Pedagogical Approaches for Sustainable Development in Building in Higher Education
(MDPI, 2021-09-13)
Education for sustainable development (ESD) is one of the great challenges that university faculties have to face. Therefore, a multidisciplinary team from the faculty of Engineering of Gipuzkoa (EIG) at the University of ...
Environmental Assessment of University Campuses: The Case of the University of Navarra in Pamplona (Spain)
(MDPI, 2021-08-01)
Current European environmental sustainability standards call for achieving a reduction in energy consumption and CO2 emissions for a horizon set in the year 2050. It has been verified that buildings and cities have a higher ...
Use of Flat Interwoven Wooden Strips in Architecture and Construction. Simulation and Optimization Using 3D Digital Models
(MDPI, 2021-06-04)
This research aims to promote the use of natural materials in construction. Its purpose is to rediscover the interlacing of flat wooden strips. Attending to environmental criteria, it focuses on the study of wood from a ...
Influence of Lewis acidity and CaCl2 on the direct transformation of glucose to 5-hydroxymethylfurfural
(Elsevier, 2021-06-11)
[EN] Nb-Zr oxides were evaluated for glucose dehydration to 5-hydroxymethylfurfural. A linear relationship was found between the amount of acid sites and niobium content. Pure Nb2O5 showed the highest acid concentration ...
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 ...
