Stora Enso Oyj is a Finnish pulp and paper manufacturer, formed by the merger of Swedish mining and forestry products company Stora and Finnish forestry products company Enso-Gutzeit Oy in 1998. It is headquartered in Helsinki, and it has approximately 29,000 employees. Following the merger, English became the lingua franca of the company, with implications for the effectiveness of internal business communications. In 2002 it was the fifth largest pulp and paper manufacturer in terms of revenue and in 2005 it was the world's largest pulp and paper manufacturer in terms of production capacity. Solidium is the biggest owner in the company. The Wallenberg family through their foundation asset management company FAM is the second biggest shareholder in the company. Wikipedia.

The invention relates to a polymer-coated packaging material, a method of manufacturing the same, and products, such as a disposable drinking cup, made from the material. The packaging material comprises a fibrous base (1) of paper or board and an extruded polymer layer (2) containing a blend of (i) 0 to 25 wt-% of a branched low-density polyethylene (LDPE)with a lower melt viscosity and (ii) 75 to 90 wt-% of a linear low-density polyethylene (LLDPE) with a higher melt viscosity. The packaging material of the invention comprises multilayer coatings, e.g.an adhesive innermost and a heat-sealable outermost layer (2, 4) of said blend and a vapour barrier middle layer (3) of at most 90 wt- % of high density polyethylene (HDPE). The layers (2, 3, 4) are brought and adhered to the fibrous base (1) by coextrusion. To maximize renewability of the materials HDPE and LLDPE as used for the structure are of biologic origin.

The invention discloses a method of continuous cooking cellulose fibrous material in a digester, said digester having a top and a bottom. The method of the invention comprises the steps of: -feeding a slurry comprising cellulosic fibrous material and cooking liquor into the top the digester, -feeding a first washing liquor into the bottom portion of the digester, which first washing liquor moves counter currently up through at least part of the digester, -removing pulp from the bottom of the digester, -feeding a second washing liquor into the center of the digester at least at the level of a first screen section, -feeding a third washing liquor into the center of the digester at the level of a second screen section, and -withdrawing the cooking liquor and the washing liquors from the first screen section and from the second screen section, which first screen section is arranged in a lower part of the digester and which second screen section is arranged below said first screen section. Thus, in accordance with the invention, a third washing liquor is added to the center of digester at the level of an additional, second extraction screen section arranged in the lower part of the digester. The method makes it possible to increase the production rate in the digester but still maintain or even increase the washing efficiency.

The European paper industry is at the core of the bioeconomy, using wood, a renewable material, and Paper for Recycling (PfR) as its main raw materials for producing paper products. This industry is a strategic sector in the EU economy, actively contributing to the re-industrialisation of Europe. Currently, the production of paper and board in the EU is 91 tonnes per year, while PfR represents 63%. The contribution of PfR has increased over the last few years (from 25 t to 40 t). This increase in the availability of PfR has not taken place in all EU states, and this is especially true in Eastern European countries. Besides, although high collection rates are achieved, the quality of this material does not always meet the requirements of paper recycling. Both facts make difficult to keep up with the increases in PfR collection rates observed over the last few years if specific actions are not taken. IMPACTPapeRec aims to put Europe at the forefront of PfR collection, ensuring raw material procurement from mainly European sources through an innovative approach based on the participation of the whole paper value chain including citizens and municipalities, which is also open to other sectors. Main objective is to provide an innovative and common knowledge platform, which will enable present and future cooperation. Analysis on best practices in PfR collection and assessment procedures are delivered, considering specific local conditions. They will encourage reliable decisions and make solutions available to decision-makers ensuring the procurement and supply of PfR in Europe through the improvement of municipal paper collection. Medium-long results are: increases in PfR collection (up to 75%); 1.57 Mt/year and raw material savings of 385 million. This proposal has positive support from the EU of the commitment approved within the EIP on raw materials IMPACT - Introduction and Improvement of Separate Paper Collection to avoid landfilling and incineration.

EFFORTE draws a red line through critical, cost/benefit driving processes, and environmentally concerns of todays forestry. Starting with efficient fulfilment of various customer demands the red line goes along efficient utilization of Big Data sources, present knowledge and critical new knowledge foreseen as outcomes from this project. Technical development and mechanization has been a winning concept for high productivity now emphasizing more gentle methods and just in time deliveries to different industry customers. This is possible to reach if new knowledge, improved methods and technical development are combined with better transfer of information and data from different sources (e.g processes, geo data from LiDAR scanning, other conditions such as weather data etc).These Big Data sources have been available for some years, but it is not until recently that hardware, data communication and merging possibilities enable full potential for a revolution of new applications. In the EFFORTE proposal we have identified three main subjects that have specific importance for efficiency, productivity and environmental concern in forest practice. Two of these implies to increasing crucial knowledge and the third, Big Data applications, combines the new knowledge with high resolution information sources into practice increasing efficiency in forest management and the connected value chains. The main objectives of EFFORTE are: i) To develop scientifically firm and techno-economically feasible methodology to predict trafficability prior to forest operations. ii) To increase forest growth and productivity of tree planting and young stand management iii) To develop, customize and pilot modern Big data solutions that will increase productivity and decrease negative environmental impact (e.g. soil, water and reduced fuel consumption). By EFFORTE we expect to make difference in efficiency, productivity and sustainability for a growing Bio-based economy in Europe.
