The paper and pulp industry saw an increase in the number of mergers in 1980s and 1990s. There had been consolidation of a number of smaller companies into larger corporations, which have greater management, financial, and marketing power. This merging trend has resulted in a fewer number of firms and an increasing concentration in the industry. Although the number of firms has decreased, the total industry capacity has been increasing. The combination of these interesting factors has motivated the topic of this masters thesis. The primary purpose of this research is to explore the factors that positively influence a firms decision to vertically integrate into producing its own pulp.

ACPEL devices were fabricated onto various paper substrates. The dielectric and phosphor layers were mask printed, a PEDOT:PSS/SWCNT ink was inkjet-printed for the cathode and a translucent conductor was applied with a paintbrush for the anode resulting in a maximum luminance of 8.05 cd/m2 at 300 VAC and 60 Hz. It was found that the conductivity of the PEDOT:PSS/SWCNT ink on the various paper types was affected by the coating and paper thickness. Novel ACPEL devices were also fabricated by incorporating paper as the dielectric layer of the device. The maximum luminance achieved was 7.24 cd/m2 at 300 VAC and 60 Hz. It is shown that the dielectric constant of the paper and hence the performance of the resulting EL device may be enhanced by filling the sheet with BaTiO3 and by the surface treatment of the sheet.

North America is the world’s largest pulp and paper producing region as well as the largest consuming region. An understanding of market integration is critical for designing relevant policies since it is important to improve national welfare and ensure long-run competitive market equilibrium. In addition, it is crucial for the Canadian industry to maintain the competitiveness for its pulp and paper products in the world market, because any deterioration in the performance of the Canadian pulp and paper industry will have negative social and economic impact on the well-being of Canada and affect Canadian balance of payment. This thesis contains three essays that investigate the market integration of the combined markets of Canada and the US, and the competitive position of Canadian pulp and paper products in the US market. The first essay presents an econometric analysis of spatial integration of the US and Canada newsprint markets as reflected in newsprint prices. It applies the Johansen multivariate cointegration procedure to test the law of one price for five regional markets (British Columbia, Ontario, Quebec, US east, US west) of newsprint using monthly data for the 1988 to 2004 period. Preliminary data analysis shows that all price series are non-stationary I(1) processes. The hypothesis that the Law of One Price (LOP) holds for all five regional newsprint markets simultaneously was not supported by the Johansen multivariate test. The LOP was also tested for national markets, and it was found to hold between US west and US east newsprint prices. The results suggest that there is a single newsprint market in the US, whereas there are several distinct newsprint markets in Canada. The second essay examines the degree of market integration among US import markets for three pulp and paper products, and further analyses the dynamic interaction between US domestic and US import markets. Persistence profile results show that long-run equilibrium exists in the US import markets for three pulp and paper products of interest; moreover, given a system-wide shock, a new equilibrium could be reached in a relatively short period. Forecast error variance decomposition suggests that US markets are critical since shocks to domestic US prices for relevant pulp and paper products explain a substantial amount of movements in import prices. The third essay studies substitution between main categories of imported pulp and paper products and between imported and domestic pulp and paper products in the US market. A restricted translog subcost function approach was employed to derive the elasticity of substitution. The results suggest that Canadian pulp and paper products are still competitive and have maintained their competitiveness in the US market. However the consecutive demand decline for pulp and paper in the US has brought hard times to Canada. It seems that if Canadian pulp and paper industry wants to retain a dominant position in the world market place, it will have to create global reach and develop new markets.

Mondi Dynäs is a pulp and paper producer in the north of Sweden close to the town Kramfors. Last year Mondi Dynäs produced 231,404 tons of Kraft paper. In order to increase their production to 300,000 tons of paper per year this study was done in order to investigate how the increased biomass flow would affect the generation of steam along with the steam and condensate balance. This study started with a mapping of the current steam and condensate balance for one winter period January – Mars and one summer period July – September 2015. The resulting balance is used as reference period for the development of the future steam and condensate scenario where Mondi Dynäs will achieve the targeted production of 300,000 tons of paper per year. The future model shows that the future production of paper will give an abundance of biomass since the generation of steam will be more than sufficient. For the winter period the venting of steam over roof could be derived to 11.9 tons per hour and 34.4 tons per hour during the summer period. This can be compared to the current situation where the winter period gave an average steam blow out of 8.7 tons per hour and for the summer period 13.1 tons per hour. To utilize the accumulated energy from these energy streams, three different scenarios was studied. The first scenario were a future installation of a backpressure turbine along with a condensing turbine section. The new turbine would be attached to the highest pressure level at 65.5 bar and have a backpressure exhaust at 20 bar which will give a power of 7.6 MWe. The second scenario included the implementation of a new condensing turbine with the current system design for the steam network and boilers. This turbine would be attached to the 3.5 bar network and give the electricity power of 1.9 MWe. The third scenario included the installation of a new bark dryer. This would give Mondi Dynäs the possibility to sell bark to an external actor on the energy market. From derived figures in the future scenario model it would be possible to sell 108,144 MWh of bark while running the bark boiler. Mondi Dynäs AB is recommended to add a new condensing turbine to their steam network. The new turbine would be able to produce 1.9 MWe and need a cooling water flow of 190 tons of water per hour. Derived figures for the investment shows a NPV of 0.6 MEUR and the IRR value of 31 %

The aim of the thesis is to investigate local impacts of large investments. This problem has been approached from three directions and, therefore, the study consists of three themes, namely: the changing spatial patterns of corporate activities, the short-term local economic impacts of invest­ments, and the long-term socio-economic impacts of investments on the local municipality. In order to put the impact studies of investments into a broader context the first theme provides an analysis of the macro-orientated processes that change the spatial pattern of a forest- based industry. The empirical investigation is based on a case-study of a major Swedish forest company (SCA — Svenska Cellulosa Aktiebolaget), analysing its development from the 1950s to the present (Paper I). The locational changes of production plants, sales units and headquarters have been mapped and, parallel to this study of the company's spatial evolution, the underlying corporate strategies are discussed. The second theme focuses on the short-term local economic impacts of investments which are carried out at production units. The empirical data has been collected from a major investment introducing a new technology (Light Weight Coated paper - LWC) at Ortviken, an SCA-owned paper mill in Sundsvall. The point of departure for the analysis is the identification of contracted suppliers and their location in order to obtain a picture of the investment's diffusion in the local economy. As the choice of supplier is an important part of the study, criteria on how suppliers are chosen have also been examined (Paper II). Moreover, by using results from a number of similar investment studies, an attempt is made to summarize general experiences within a tentative model for estimating the share of local purchase deriving from major investments: the Local or Non-Local (LNL) model (Paper III). The third theme of the thesis pinpoints long-term local impacts of large investments. The investment generates impacts not only concurrently with the implementation phase, but also during the operation period of the invested item. The investigation of long-term socio-economic impacts has been performed by two studies employing different methodological approaches. The first study (Paper IV) deals with ex ante local impacts of locating a nuclear waste repository in Storuman or Mala, two sparsely populated municipalities in northern Sweden. The model is a traditional macro- formulated cohort model which is combined with a 'basic/non-basic' assumption regarding the intcrdependency within the local trade and business. The second study (Paper V) refers once again to the forest-based industry by emphasising the long-term socio-economic impacts of the investment examined in Paper II. This paper employs a micro-analytical modelling approach, so that, the municipal population is represented individually within the model. A microsimulation model is elaborated in order to analyse the long-term (15 years) local population and labour market dynamics induced by the LWC-investment. Some major findings of the thesis are: * The share of local purchase is connected to the composition of the investment. Analyses have shown that the higher the technological demand and the more technically advanced the goods and services related to the investment, the smaller is the local share of the purchase. *  It has proved possible to trace chain effects on different local labour-markets induced by changes in production at a particular place of work. Through linkages between the partial labour markets the closure of a major place of work will not only affect the occupational groups to which laid-off employees belong, but also give rise to changes in unemployment levels in many other occupations. / digitalisering@umu

Coated wood free. For this identification was applied a strategy of data evaluation through structured interviews with four professionals with experience in the Paper Sector. It was used information issued in articles, magazines, dissertations, newspapers and on top of that primary and secondary data from the Pulp and Paper Sector were used, specifically the coated wood free for printing segment. The study had as assumption that there was loss of competitiveness in the Brazilian market, and the main factor responsible for this loss could be attributed to a systemic factor, the exchange rate. There was an increase of importation and reduction of exportation in the period of the study. The main factors identified in the interviews in sequence of importance and according to the interviewers were; exchange rate, the illegal usage of duty free operation during the importation and the lack of update the industrial equipments in the Brazilian Mills The currency, as a main factor of competitiveness loss for the Coated paper sector and it was confirmed through the evaluation of secondary figures of importation grow and exportation reduction in the period of 2003 till 2008. Other factor, the illegal usage of duty free operation during the importation, was based only in the perception of the interviewers; there were no dada available due to the subjectivity of this topic. The third factor, the lack of update the industrial equipments in the Brazilian Mills appointed during the interviews. It could be confirmed in the analyze of the world?s fastest paper machines and more competitive in the world in comparison with Brazilian?s paper machines which speed are very far from the more competitive machines in the world. The Brazil is not even mentioned in this article of machines caparison. When the factors that determine the competitiveness of printing coated papers are analyzed in group, the conclusion is that Brazil is not competitive in this segment due to several business factors. The currency that is a systemic factor and appears in the periods of currency valuation works in the process of exposure of the low competitiveness already existent. / Este trabalho teve como objetivo identificar os principais fatores que levaram a ind?stria brasileira de papel de imprimir revestido, o Couch?, ? perda de competitividade. Para identifica??o desses fatores foi aplicada a estrat?gia de an?lise de dados atrav?s da realiza??o de entrevista estruturada com quatro profissionais experientes ligados ao setor de pap?is, informa??es publicadas em artigos, revistas, teses e disserta??es, alem dos dados prim?rios e secund?rios do setor de celulose e papel, especificamente os do segmento do papel de imprimir revestidos ? o Couch?. Dentro deste objetivo foi adotada a suposi??o de que houve perda de competitividade no mercado brasileiro, e que um dos principais fatores da perda desta competitividade poderia ser atribu?do a um fator sist?mico, o cambio, havendo aumento das importa??es e redu??o das exporta??es no per?odo estudado. Os principais fatores identificados nas entrevistas, por ordem de import?ncia e segundo os entrevistados, foram: o cambio, a pr?tica desleal de isen??o tribut?ria e a falta de atualiza??o do parque industrial brasileiro. O cambio, como principal fator de perda de competitividade do setor de pap?is revestidos, pode ser corroborado atrav?s da an?lise dos dados secund?rios de importa??o crescente e exporta??o declinante no per?odo analisado de 2003 a 2008. O outro fator de pr?tica desleal da isen??o tribut?ria ficou apenas na percep??o dos entrevistados, n?o havendo dados dispon?veis para sua avalia??o pelo pr?prio grau de subjetividade deste tema. O terceiro fator de perda de competitividade apontado nas entrevistas foi a falta de atualiza??o do parque industrial brasileiro. Isto pode ser confirmado pela an?lise dos dados das m?quinas de papel mais velozes e competitivas do mundo em compara??o com as do Brasil, cujas velocidades est?o muito aqu?m das mais competitivas do mundo. O Brasil n?o ? sequer citado no artigo comparativo. Quando os fatores determinantes da competitividade dos pap?is de imprimir revestidos s?o analisados em conjunto, observa-se que o Brasil n?o ? competitivo neste segmento devido a diversos fatores empresarias. Quando a quest?o cambial, que ? um fator sist?mico, aparece em per?odos de valoriza??o cambial, este somente exp?e e agrava mais ainda esta baixa competitividade existente.

Magnesium oxide-based additives have been used in kraft recovery boilers to minimize deposit accumulation on superheater and generating bank tubes. Due to inconclusive results observed in boilers and claims made for additive effectiveness backed by little scientific evidence, only a few mills still use the additives for fouling control. A systematic study was performed to examine the effect of MgO-based additives on deposit accumulation and removal under controlled laboratory conditions, and to evaluate the additive effect in a kraft recovery boiler. The results show that while the additive coating has no effect on deposition, it could ease deposit removal if a coating greater than 5 µm can be applied on the tube surface effectively. Separate injection of additive and black liquor had insignificant effect on deposition and removal. Results of the field study show that the amount of additive collected on the tube is too small to have an impact.
