Study of a renewable capping agent addition in lignin base catalysed depolymerisation process
(Elsevier, 2020-07-13)
The aim of this work was to study the influence of a renewable capping agent (CA) in the production of monomeric compounds from the depolymerization of an organosolv lignin (Pinus radiata) by a base catalyzed depolymerization ...
Valorization of cheese whey: closing the loop from protein extraction to whey protein film composting
(RSC, 2024)
Whey protein extracted from cheese-making by-products was analysed as a potential alternative for both food waste valorisation and food packaging waste reduction. Whey protein was ultrafiltered from local cheese whey and ...
5-Methoxymethyl furfural production by acid heterogeneous catalytic etherification of 5-hydroxymethyl furfural
(Elsevier, 2024-01)
The use of non-edible raw materials from agriculture as a form of biomass to obtain carbon-based compounds is the most viable solution to replace fossil resources. Within this, 5-hydroxymethyl furfural (HMF) is a platform ...
Effect of Sulphate-Reducing Bacteria Activity on the Performance of Thermally Sprayed Aluminium and Polyurethane Coatings
(MDPI, 2024-03-06)
In the present work, we studied whether the exposure of synthetic seawater with anaerobic sulphate-reducing bacteria (SRB) on some steel samples generates a bacterial biofilm in their surfaces. Bare steel belonging to a ...
Kraft and organosolv lignin-activated carbon composites for supercapacitor electrode materials
(Elsevier, 2024-03)
Lignin-activated carbon (AC) composites were employed as electrode active materials to develop more environmentally friendly Supercapacitor (SC) materials with enhanced properties. This way, the hydroquinone/quinone moieties ...
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 ...
Chitin nanowhisker-containing photo-crosslinked antimicrobial gelatin films
(Elsevier, 2024-02)
Nearly 57 Mt of food waste are generated annually in the EU for many reasons, for instance, because of microbial food spoilage. So, actions to reduce food loss and waste are needed and active packaging could offer a new ...
Pectin and pectin/chitosan hydrogel beads as coffee essential oils carrier systems
(Elsevier, 2024-06)
Two pectin fractions extracted from coffee pulp, one high-methoxylated (Coffea arabica pectin, CAP) and other low-methoxylated (chelating agent-soluble pectic fraction, CSP), were used for the development of hydrogel beads ...
Valorisation of Sub-Products from Pyrolysis of Carbon Fibre-Reinforced Plastic Waste: Catalytic Recovery of Chemicals from Liquid and Gas Phases
(MDPI, 2024-02-21)
Waste carbon fibre-reinforced plastics were recycled by pyrolysis followed by a thermo-catalytic treatment in order to achieve both fibre and resin recovery. The conventional pyrolysis of this waste produced unusable gas ...
Strategies for Improving Sustainability in the Development of High-Performance Styrenic Block Copolymers by Developing Blends with Cellulose Derivatives
(MDPI, 2024-03-21)
Next-generation high-performance polymers require consideration as sustainable solutions. Here, to satisfy these criteria, we propose to combine high-performance styrenic block copolymers, a class of thermoplastic elastomer, ...
