|More value from raw material by fractioning|
|New value chains can be created by wood fractionation. Pine logs with three different growth rates were fractionated and pulped. Fractionation of chips was done using so called dense media fractionation method. The mechanical pulping trials revealed that density is very important raw material parameter in terms of energy consumption and pulp quality. The energy consumption difference of the fractions was 47 %. Paper samples made from pulp were also analysed.|
|New products from forest bio-refinery|
|A more efficient recovery of value components from the wood material and by-products at existing pulping mills provides them with the opportunity to gain additional value from the wood raw material in addition to pulp production.|
|Effect of the thermal conductivity of synthetic and metal fabrics on the drying efficiency|
|Dryer capacity can be increased by using preheated fabrics with higher thermal conductivity. In the conference presentation the fabric thermal conductivities were determined and this information was used to estimate the dryer capasitities. Both synthetic and metal fabrics were used. See the conference presentation behind the read more link.|
|Lean development with renewable resources|
|Lean development with renewable resources (LEADER). The aim of the LEADER project (2007-2010) was to study the environmental impacts occurring during the life cycle of print products. The scope of the project was focused on printed media products. The main products in the print media product group are newspapers, magazines, books and advertisements. Project final report is now published.|
|Ongoing project: IQ-Freshlabel (2010-2013)|
|IQ Freshlabel project aims at promoting the implementation of novel smart labels (intelligent packaging) through investigation of consumer, retailer and industry interest. Development of novel smart label to monitor temperature abuse of frozen foods and to monitor oxygen content in modified atmosphere packaged products is also carried out. Have a look of project participants and focus behind the link.|
|Health and environmental safety aspects of friction grinding and spray drying of microfibrillated cellulose|
|Health, safety and environmental issues of nanomaterials have recently raised many concerns. In this study we evaluated the worker exposures to nanoparticles in air during production of nanocellulose. We also exposed mouse macrophages and human monocyte derived macrophages to nanocellulose in vitro and studied the viability and cytokine profile of the cells thereafter (study carried out at Finnish Institute of Occupational Health). In addition, we studied ecotoxicological effects of nanocellulose using the kinetic luminescent bacteria test with Vibrio fischeri.|
