During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.

At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.

The technical development is advancing at high speed and now the turn has come for the traditional paper to digitalize into the so called e-paper. The newspaper industry has started to investigate the future possibilities of publishing the traditional newspapers on e-paper. Today?s newspapers are mostly financed by advertisement incomes, which makes the advertisers important players, who must be taken into consideration at an introduction of the e-paper. Since the e-paper does not exist as a finished product in the market today, in this essay we look into what kind of functions or services that can attract advertisers to the e-paper on the basis of the experiences made with the breakthrough of the web-newspapers.

Jag har ett huvudsyfte och ett delsyfte med denna uppsats. Huvudsyftet är att studera familjehemmet som ett komplement till det biologiska hemmet och delsyftet är att se i vilken utsträckning John Stuart Mills teorier är tillämpbara i Förenta Nationernas (FN) konvention om barns rättigheter. För att kunna genomföra studien kommer jag att ha följande frågeställningar: Vilka barn ska enligt lagstiftningen placeras i familjehem? Vilka mål finns det med en familjehemsplacering? Hur går en utredning till när ett barn ska placeras i familjehem? Vad krävs av familjehemmet för att barn ska placeras där? Jag behandlar endast familjehem i Sverige och de barn som uppfyller kraven för att placeras i familjehem. Slutsatsen är att barn som utsätts för bland annat misshandel och sexuella övergrepp i det biologiska hemmet kan placeras i familjehem.

The aim of this thesis is to investigate the correlation between the price of electric power and investments within the Swedish basic industry. Using regression analysis, the authors test for correlation between the electricity prices and the basic industry, defined as the pulp and paper industry, the mining industry, the steel and metal industry and the basic chemical industry. Moreover, five variables found in the literature on investment decisions are being used as a means of comparison. The results suggest that the electricity price affects the investment decisions within the basic chemical industry as well as the steel and metal industry. On a more abstract level, this thesis contributes to the understanding of one of the properties of the Swedish GDP..

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.

The need of raw material does of course fluctuate but the long term view is an increasing demand due to the growing consumption of sawn timber products, pulp, paper and lately also biomass. This has led to a keener competition for wood. At the same time there is an ongoing structural change of a significant part in the Swedish wood supply market, the private forest owners. In 1992, 22 % of Sweden´s 335 000 private forest owner lived apart from their forest. In 2007 this figure had risen to 36 %.

This paper examines the structure of The Golden Notebook and in which way it reflects thethemes in the novel. This paper also describes the context of the 1960`s in which a certaintype of ideas were developing and wants to place The Golden Notebook in this context. Finallythe paper investigates what can be understood by reading the novel as a part of that context..

Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.

This paper focuses on the employers? responsibility as described in the 11th section in the Employment (co-determination in the workplace) Act of 1976. The questions asked are to determine whether the law in the 11th section is followed in real life and if the consequences for breaking the law are a deciding factor. This paper summarizes the law as it is interpreted today and in what situations it is applicable. Since the law and especially section 11 affects certain individuals and organizations, the paper also describes who these individuals and organizations are and how they are affected.

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.
