New developments in the Extraction department 04 Avr 2013
CELABOR is active in plant extraction and possesses laboratory and pilot scale extraction equipment. The centre gives priority to the development of environmentally friendly processes. Those various green processes enable a major decrease in the volume of fossil solvents and/or the energy needed for the extraction.
Amongst these eco-processes, the use of heated and pressurised solvents is an excellent alternative to classical solvents: supercritical CO2 (in place of hydrocarbons) for apolar compounds and subcritical water (in place of alcohols) for polar compounds. The use of these extraction processes will be the focus of the conference given by Stéphane KOHNEN, PhD, on April 16th for the ... Read more

New pelletiser for natural fibres used in composite materials 25 Fév 2013
In the context of the CILAB project, supported by the Walloon Region and FEDER, Celabor has jus acquired a laboratory machine to produce pellets.
During some projects about reinforcement of plastics by natural fibres, it appeared that it is very difficult to feed and above all to dose fibres into the melted polymer.
The method consisting of transforming the fibres into “pellets” allows a correct and even feeding and thus a more homogeneous dispersion of the fibres in the compound.
Those pellets must have a density such that they can disintegrate easily in contact with the polymer, which is the composite matrix.
Therefore Celabor decided to invest in a laboratory pelleting machine, in order to be able to produce the pellets themselves ... Read more |
Agrocalage: Development of cushioning materials derived from agro-regional resources 20 Fév 2013
Since 2009,CELABOR is involved in the project Agrocalage to develop new cushioning materials derived from agricultural resources.
Agrocalage, it’s…
… An Interreg IV project
European cross-border cooperation program that aims to strengthen economic and social exchanges between Nord-Pas de Calais, Champagne-Ardenne and Picardy in France, and Wallonia and Flanders in Belgium.
…Two partners
CELABOR (Wallonia) and l’Ecole Supérieure d’Ingénieurs de Reims (France).
… An initial problem
Border regionsof Wallonia and the French Ardennes are characterized by 'traditional' industries requiring an economic transformation. New activities, such as plastics, effectively contribute to the diversification of the industrial base. Another common point of these two border regions is the predominance of agriculture and the availability of agricultural resources. The AGROCALAGE project is set in ... Read more

Analysis of short natural fibres for composite materials 15 Jan 2013
In the context of the CILAB project, supported by the Walloon Region and FEDER, Celabor had already acquired two devices based on image analysis to be able to characterize the granulometry and morphology of natural fibres used as reinforcement of polymers in the injection and extrusion processes. Every device having its own limits as far as fibre dimensions are concerned, Celabor has just purchased a 3 rd system, the brand new Occhio analyser based on the scanning principle (Scan600). This device will be complementary to the 500Nano system and will allow a better knowledge of the longest fibres thanks to bigger image dimensions.
A complete set of devices for the analysis of short natural fibres or particles is therefore available at Celabor.

SOLAPACK : new project on preventing the migration of critical substances from the packaging into foodstuff 16 Nov 2012
SoLaPack is an acronym for Sorption Layers for paperbased Packaging materials. The project has started in May 2012.
The objective of this CORNET project is the development of concepts to ensure that critical substances cannot migrate in to the packaged food. Therefore sorption materials have to be incorporated into coating formulations to selectively sorb benzophenone, bisphenol A, phthalates and mineral oil from inks, varnishes, adhesive and recovered paper. A coating on the product side should prevent the contamination of food by migration of these substances, so that the critical values are not exceeded.
There are several steps in this project: characterisation of sorption materials, production and characterisation (by migration tests amongst others) of sorption layers, functionalisation and optimisation of sorption layers and finally a profitability study of the ... Read more |
New subcritical water extraction pilot 04 Oct 2012
CELABOR recently acquired a unique equipment, used to extract solids with pressurized superheated liquids up to 200°C and 250 bars.
This allows for a significant reduction of the extraction time and the volume of solvent needed for the extraction.
One of the main goals of this installation is subcritical water extraction, i.e. liquid water heated at more than 100°C under pressure.
In addition to improved efficiency, water can sometimes substitute for solvent such as ethanol, with a significant improvement in terms of costs and explosion hazards.
First tests show that the treatment of vegetal matter done by CELABOR gives promising results.
Finally, the equipment is Atex certified and can be used with flammable solvents such as ethanol, acetone or hexane, ... Read more |
