Sustainable production of cellulose nanofiber from sugarcane trash: A quality and life cycle assessment
(Elsevier, 2021-09-29)
Developing green processes in the chemistry and engineering domains is one of the most significant challenges for sustainable production. Sugarcane trash (ST) generated during the sugar extraction process is an excellent ...
Study of the influence of reutilization ionic liquid on lignin extraction
(Elsevier, 2015-04-09)
The development of green techniques for biomass processing and fractionation is crucial from the point of view of sustainability and environmental protection. Lignin is the second most abundant bio-renewable material on ...
Willow lignin oxidation and depolymerization under low cost ionic liquid
(ACS, 2016-05-10)
Willow biomass was subjected to different pretreatmentconditions with triethylammonium hydrogen sulfate as solvent, andthe produced lignin solutions were treated by oxidation either homo-geneously using H2O2as oxidant or ...
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 ...
Solvent and catalyst effect in the formic acid aided lignin-to-liquids
(Elsevier, 2018-09-13)
[EN] The effect of the type of solvent, ethanol or water, and a Ru/C catalyst were studied in the formic acid aided lignin conversion. The best results were obtained in the presence of the Ru/C catalyst and using ethanol ...
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 ...
