Naturhänsynen i FSC-standarden : vetenskap eller gissningar?

The Swedish FSC standard (Forest Stewardship Council) is a level standard used to certify forestry. All the major Swedish forest companies are using the FSC standard, and approximately 50% of the Swedish forests are FSC certified today. In the essay six items within the chapter on environmental issues and biodiversity are examined: the proportion of protected forest, the proportion of annually burnt clear-cut stands, the number of trees with large diameter, the amount of dead wood, the proportion of deciduous trees within a stand and the proportion of deciduous-dominated stands. The FSC standard states a level for all items, and the purpose of the essay is to analyse whether these levels are supported by research within the field of conservation biology. The validity of the levels of the six items is them discussed to evaluate whether changes are required to the next revision of the FSC standard.

Hållbar konsumtion av nötkött och mjölk

Sustainable beef and milk consumption. The consumption of beef and dairy products in Sweden is high. A lot of greenhouse gases are emitted from the production of these products. The production of beef in Sweden has decreased but the import has increased. The number of dairy cows has decreased while beef-production with suckler-cows has increased in Sweden.

Ansvarsfull produktion ? vägen till kundens hjärta?

Responsible production is a subject of increasing importance for companies toadopt and communicate to their environment and many companies choose to implementenvironmental ? and ethic considerations into their brand strategy. There is, however, adividing line between companies according to what extent they choose to implementresponsible production into their brand strategy and to which extent they choose tocommunicate it to their stakeholders and surroundings. It is the hypothesis about a dividingline that is the foundation for this essay and something we believed could be interesting forfurther analysis.The purpose of our essay is to find out how the brand strategy of a company is affected by theresponsible production and in what extent they communicate it to their environment. Byanswering those questions we hope to find out why some companies communicateresponsible production more actively than others.We have conducted in-depth interviews with the Swedish clothing companies; MariaWesterlind, Zion and Dem Collective and we have through our analysis reached interestingconclusions.

The effect of new raw materials on pellet prices

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

Skördemetoder av industrihampa :

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

Reducering av ledtid genom en värdeflödesanalys En fallstudie på Lammhults Möbel AB

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

Humanioran och Open Access ? en kvalitativ studie i drivkrafter och strategier hos litteraturvetare inför publicering

The natural sciences and the humanities are associated with differentpublishing patterns. Open Access publishing are mainly associated withthe publishing patterns of the natural sciences. Many Swedishuniversities and research funders are proponents of Open Accesspublishing, what will that trend mean to the scholars with a publishingpattern not corresponding to Open Access? In this paper literary scholarsare interviewed for the purpose of learning the motives and strategieswhich form their publishing pattern, and how they relate to Open Accesspublishing. The results show that literary scholars are less competitiveand hold a more gentle knowledge-sharing ideal, than natural scientists.The drive to gain acknowledgment and the recognition of colleagues inorder to collect academic capital as Bourdieu describes the academicfield is still present though.

Förbättring av upplösningen i Landsat 7-bilder med hjälp av bildfusion

The purpose of this master's thesis is to evaluate whether it is feasible to use the panchromatic band of Landsat 7 in order to improve the spatial resolution of colour images. The images are to be used as texture in visual databases for flight simulators and for this reason it is important that the fusion preserves natural colours.A number of methods for fusing panchromatic and multispectral images are discussed. Four of them are implemented and evaluated. The result is that standard methods such as HSI substitution are not suitable for this purpose since they do not preserve natural colours. However, if only high frequencies of the panchromatic image are used the resolution can be improved without noticeable colour distortion..

Miljövärdeflödesanalys av Risifruttiproduktionen : En utvärdering av värdeflödesanalys och miljövärdeflödesanalys

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

Sockerproduktionens skilda utveckling i u-länder : En jämförande fallstudie av Moçambique och Tanzania

How affected are the sugar production in Mozambique and Tanzania by EU sugar regime? What does the EU sugar reform constitute in these countries?Using theories regarding free trade and anti-free trade, I am able to answer these questions. The aim of this paper is to study how the various sugar agreements with EU affect the sugar production in Mozambique and Tanzania. Therefore I am using a method called a most similar system design in this comparative case study. The conclusion is that the EU sugar regime is the main reason to how the sugar productions in developing countries are.

Natur på skolgård : värdet av naturlika miljöer och deras utformning för barn

As a result of my fascination for nature I have chosen to study the possibilities to introduce natural environments on schoolyards. Too many schoolyards are lacking vegetation and many of them look like sterile asphalt deserts. The master thesis consists of two parts. The first part is based on literature studies and the second part in which findings from part one are put into practice. Five examples are presented; four schoolyards in Malmö; Kryddgårdsskolan, Kirsebergsskolan, Rörsjöskolan and Lindängeskolan and one in Kalmar; Åbyskolan. Malmö Naturskola has been working with the chosen areas on the schoolyards in Malmö.

Fiberföstärkning av Limträbalkar

Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.

The wine production in FYROM : does the wine sector have a comparative advantage?

The aim of the thesis is to see if the wine production in FYROM has a comparative advantage compared to other countries that produce wine and if FYROM is able to sustain the advantage in the future. The countries chosen for comparison are Bulgaria, Croatia, France and Italy. The methods used in the thesis are the Balassa Index and Porter?s Diamond of National Advantage.

Design of Production Contracts : an examination of the Findus pea production contract

The Swedish processor Findus contracts approximately 500 pea producers annually to secure the company?s supply of green peas for human consumption. A production contract, which has had roughly the same design for decades, regulates the relation between Findus and the pea producers. Agriculture is typically a risky business. The main sources of risk in agricultural production are production risk and price risk.
