SUNPAP workshop 2011 - First results and main challenges

Sustainable Nano Fibrillar Cellulose production, factors affecting quality and needs to modify Nano Fibrillar Celluloses for different paper and board applications.

October 5th, 2011 at VTT, Vuorimiehentie 5, Espoo, Finland

What is SUNPAP?

Scale-Up Nano Particles in Modern Papermaking (SUNPAP) is a large-scale integrating project in the European Community’s 7th Framework Programme under the NMP programme. The general aim of the SUNPAP project is to direct the paper and board production to even more sustainable use of materials and production technologies. Special attention will be paid to sustainability assessment and life cycle analysis throughout the project. The project is coordinated by Dr. Ulla Forsström from VTT Technical Research Centre of Finland (VTT), Finland. Contact: ulla.forsstrom@vtt.fi.
