Fourth "EFPG Days 2005", a huge success
(in French)

The fourth “EFPG Days” session took place in Grenoble
last October during the IP exhibition.
The “EFPG Days” are an annual international workshop aiming at presenting the
lastest research results in certain areas that have been researched at the EFPG.
Just like the last three sessions, this fourth edition was greatly appreciated
by the audience who came from pulp and paper producing companies, equipment and
chemical suppliers of these industries and researchers. This
fourth session of "EFPG Days" was focus on ozone bleaching, improvement of
chlorine dioxide bleaching, and chemical modification of fibres.

"EFPG Days", a large and
international audience
The content of the lectures was specially organized to fit an audience of
industry people interested in pulp bleaching and fibre chemical modification
issues, as well as suppliers willing to know about new opportunities for their
products or equipments.
30% of this audience consisted of foreign participants, originating from
Brazil, Sweden, Finland, Switzerland and Slovakia.

Session |
|
Ozone bleaching, improvement of chlorine dioxide bleaching, and chemical modification of fibres
The topics presented at the fourth session included the following :
 |
|
Bleaching and treatment of chemical and mechanical pulps with ozone (40% of the
presentations). The EFPG has a strong expertise on ozone bleaching and chemistry
and participated to several industrial developments. Michel Muguet, Manager /
Pulp & Paper Industry, from l’Air Liquide, gave a status of the industrial
development of ozone in the pulp and paper industry : 26 mills are using ozone
today compared to zero, fifteen years ago; |
 |
|
|
New ways to improve chlorine dioxide bleaching.
Chlorine dioxide has been the
major reagent used to bleach chemical pulps for the last thirty years. There is
still room for optimisation of this reagent as it has been shown that about 40%
of the chlorine dioxide is wasted in secondary reactions during the bleaching
process |
|
|
|
Chemical modification of cellulose fibers
to improve their papermaking
properties or for new products development and potential of use of micro and
nano cellulosic particles. The EFPG has been working on these topics for many years
and presented some of their results. For example, different ways to create
carboxyl groups on cellulosic fibers, as well as the interest of chemically
modifying the surface of fiber for their incorporation in composites for
packaging applications were presented. |
|
|
|
Production of micro and nano sized
vegetal particles, and their potential usages were also discussed |

Next "EFPG Days" Session
Please note that the 5th edition of the "EFPG Days" will be held between May 9-12, 2006 and
will focus on the use of cellulose fibres in different composites for packaging
application, as part of the European SUSTAINPACK project.
