Transparent plastic-like packaging material from birch fibril pulp
VTT Technical Research Centre and Aalto University have developed a method which for the first time enables manufacturing of a wood-based and plastic-like material in large scale. The method enables industrial scale roll-to-roll production of nanofibrillated cellulose film, which is suitable for e.g. food packaging to protect products from spoilage.
The printed newspaper is, on average, a more ecological news media than a website
The printed newspaper is, on average, a more ecological news media than a website. This conclusion is based on a comparison of the environmental impacts of one hour of consumption of each media channel. However, taking into account actual usage volume and consumption hours at the current level, the annual environmental impacts of print media generally outweigh those of a corresponding website. These are the results of a study carried out by Alma Media in partnership with leading research institutes to determine the life cycle environmental impacts of three of its newspapers and their respective online services. VTT coordinated the research.
"Future of Printing"-Open Call for project participants
Based on the findings of the project "Future of European Printing Industry", VTT is now ready to launch a set of R&D projects aiming to increase the future profitability of the European printing industry. The project themes were introduced in the printing webinar on the 23.11.2011 and the consortia are to be formed in January-February 2012. With the right consortia the projects will be ready to start in March 2012.
New biocide concepts to avoid chemical variations in papermaking
Biocide dosing can generate chemical variations in papermaking. Chemical variations can also originate from breaks and poor management of the broke. This cyclicity, where chemical variations cause breaks and breaks cause chemical variations, should be eliminated in order to restore good runnability. An in-depth study clarified the interactions of microbial activity, biocide usage, and chemical changes in the papermaking process. New biocide production methods and new measurements were applied to papermaking. For papermakers onsite-generated biocides are low-cost solutions based on actual biocide need.
Novel value perceptions and business opportunities through packaging customization
A new type of a packaging concept was developed, demonstrated and tested. In the project VTT developed for the brand owner a beverage package designed for a rock festival. The user centric design was used in the development in order to provide consumers most valuable information of the event. The concept provided also additional use for the physical package. The six-pack beverage package that was demonstrated proved to be a win-win-win -concept. It brought added value not only for the brand owner and the festival organizer but also for the consumers.
Faster drying with improved paper properties
PhD Thesis of Janne Keränen concentrates on paper drying: first on the drying rate in a cylinder covered with fabric, enhanced using hot air impingement through the fabric, and its potential effects on paper quality, and second, on the heat transfer rate from hot steam to paper through the cylinder shell. Impingement through the fabric of hot air has been suggested to cause increase in the water removal and drying of paper.
Thermal modification does not always reduce water absorption of wood
It is a popular belief that thermal modification reduces water absorption of wood and thus prevents wood decay. However an extensive study at VTT shows that this is not always the case. During experiments it was noted that even after thermal modification the water absorption of sapwood and heartwood differ a lot. When sapwood of pine, for example, was modified in different temperatures, it might, in some cases, absorb even more water after the treatment.
