Capsule recycling system for domestic coffee machines
Guglielmo Milan, Fernando Castañeda, Luca Massera
The system and method for used capsules (11), such as coffee capsules, with a lid and a capsule body, comprises at least cutting means (17) to cut the lid from the body, capturing means to extract the cut lid from the body, compacting means (12, 14) to com ...
2018Heat expandable biopolymers for one-step production of foam core sandwich composites
The overall aim of this work has been to develop sustainable solid thermally activated foam precursors suitable for the in-line production of lightweight bio-based foam core sandwich structures with consolidated wood particle facings, using a non-inflammab ...
EPFL2016Photocatalytic and Electrocatalytic Reduction of Carbon Dioxide in Pressurized Systems
The depletion of carbon-based fossil fuels and the rise in atmospheric carbon dioxide concentration will force an inevitable change in the future global energy landscape. CO2 reduction presents the advantages of decreasing its atmospheric concentration and ...
EPFL2016Processing of Sustainable Cellular Biocomposites
Petroleum-based polymers and composites are commonly used in a wide variety of application fields. However ecological concerns, increasing oil prices and dwindling natural resources explain why nowadays industrial and public interest is more than ever focu ...
EPFL2012Bioresorbable Nanocomposite Foams for Bone Tissue Engineering
The present work forms part of an ongoing effort at the Laboratory of Polymer and Composite Technology (LTC) to develop novel solvent-free processing methods for next generation resorbable porous scaffolds for bone replacement, based on supercritical carbo ...
EPFL2011Interfacial Photoreduction of Supercritical CO2 by an Aqueous Catalyst
Hubert Girault, Manuel Alejandro Méndez Agudelo, Patrick Voyame
Not just a solvent anymore: CO2 reduction under supercritical conditions was achieved in a biphasic water–supercritical CO2 system using an aqueous soluble catalyst (see picture). The introduction of such an interface provides a suitable reaction medium wh ...
2011Intégration énergétique d’un procédé agroalimentaire à l’aide de la plateforme internet PinchLight
Résumé : Les procédés agroalimentaires sont des procédés industriels consommateurs de grandes quantités d’énergie, aussi bien de refroidissement que de chauffage. Il est donc intéressant d’optimiser cette consommation. L’analyse pinch, méthode systématique ...
2010Hydrocarboxylation of Terminal Alkenes in Supercritical Carbon Dioxide
The catalytic hydrocarboxylation of linear alkenes to carboxylic acids using supercritical carbon dioxide as a solvent was studied. High selectivities in acids have been obtained. The best results were achieved when adding a perfluorinated surfactant to th ...
2008Optimised accelerated solvent extraction of PCBs and PAHs from compost
Joseph Tarradellas, Rahel Christine Brändli
This study is the first thorough method optimisation for accelerated solvent extraction (ASE) of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from chemically dried compost. For PCBs, optimised solvent composition, temperatur ...
Taylor & Francis2006Polylactic Acid–Phosphate Glass Composite Foams as Scaffolds for Bone Tissue Engineering
Dominique Pioletti, Pierre-Etienne Bourban
Phosphate glass (PG) of the composition 0.46(CaO)–0.04(Na2O)–0.5(P2O5) was used as filler in poly-L-lactic acid (PLA) foams developed as degradable scaffolds for bone tissue engineering. The effect of PG on PLA was assessed both in bulk and porous composit ...
