Scenerier i glas - ett projekt om mönstermoduler
The present project was initiated with the aim to create pattern modules for use in public environments. My intention was to let the properties, of the specific materials used, have a marked influence on the realisation of the final form. I also wanted to find a material, which is suitable from the perspective of sustainabilityand possibilities to create modules from it. The work was initiated with a study of some candidate materials and many sketches before I finally made my choice. My decision was clear after a visit to the company Glasfabriken inKalmar.
Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
Process optimization in the steel plant
Blast furnace is the heart of every steel plant. Steel production is based on the blast furnace process, as it is where the iron is extracted from the iron ore and turned into liquid iron, which will subsequently be used to make liquid steel. Therefore, without hot iron, steel can not be produced. Blast furnaces in this process are supplied among others with pulverized coal. Raw coal should be prepared for the blast furnaces in the form of fine coal powder.

Jämförelse av solhybrider
Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.
Bachelor thesis Re : bottle
There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.
Utvärdering av den gröna smileyn inom livsmedelsinspektion : En intervju och enkätstudie i Halmstads kommun
With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.
Utvärdering av miljönytta för olika miljöcertifieringssystem för byggnader : En jämförande fallstudie på Swecos kontor i Stockholm, Göteborg och Malmö
This thesis examines the environmental benefits resulting from the choice of environmental certification scheme, with focus on energy. This was carried out by studying the measures that were implemented as a result of the certification of Sweco's three largest office buildings in Stockholm, Gothenburg and Malmö. The office property in Stockholm has been certified with the Swedish Environmental Building, Gothenburg with the British BREEAM and Malmö with the U.S system LEED.The results from the study indicate that an environmental certification can reduce the energy consumption by up to 59 percent and the water consumption by 20 to 66 percent. However; the interviews, literature study and simulations in MATLAB indicate that the size and scope of these environmental benefits depend on several identified factors: the type of building and its conditions, system selection, grade level, the choice of indicators, the ambition of those involved and when in time the certification process begins. The comparison between Environmental Building, LEED and BREEAM showed that Environmental Building for the office property in Stockholm gave the largest environmental benefit in terms of reduced energy consumption thanks to several large measures.

Hägglunds has a wide background of engineering, where they have manufactured all from airplanes to lifting cranes. Currently they only produce track vehicles at Hägglunds, where they manufacture the CV90 and BVS10 models. This thesis concerns the BVS10 which is an all-terrain-vehicle. The main purpose with the BVS10 is to enable transportation of material and personnel thru tough terrain.
Ett re(el)lt hot? Om elprisets betydelse för investeringar inom basindustrin
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..
Optimering av interna trucktransporter vid Emhart Glass i Sundsvall
Resurssnål produktion är en teori om hur produktionsplanering i ett företag kan förbättras, vilket syftar till att öka effektiviteten och skapa en bättre arbetssituation för medarbetarna i företaget. Examensarbetets övergripande syfte har varit att med stöd i denna teori ta fram ett optimerat och verklighetstroget truckkörschema för dagens interna transporter vid Emhart Glass i Sundsvall. Målsättningen har varit att jämföra de interna transporterna med de behov som finns i företaget, att identifiera hur ofta transporter av tomma lastpallar sker samt att klar-göra om en dubbelpallshantering innebär tidsmässigt vinst. En kart-läggning av de interna transporterna och arbetsställenas behov av lastpallar har genomförts. Informationen från kartläggningen har implementerats i programmet Matlab, där en algoritm för beräkning av ett körschema har skapats som tar hänsyn till dagens tidshantering av lastpallar och sannolikheten att truckförarna lastar av och på lastpallar vid olika arbetsställen.
Applicerbarheten av produktanpassade supply chain-strategier inom stålindustrin : En fallstudie
AbstractThis study aims to investigate the applicability of well-recognized supply chain strategies based on product characteristics. Choosing the right supply chain strategy can be the difference between winner and loser in today?s competitive climate and science offers several recommendations as to which aspects that should be considered. Fisher (1997) and Christopher and Towill (2002) suggest that supply chain strategies should be based on what kind of product the company is handling and that, in order to know which strategy is the most appropriate, the products must be categorized. Some criteria developed for the categorization are lead time, forecast in demand and profit margin.
Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB
The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

Mikroföretag och dess marknadsföring : Thermo Steel i fokus
Bakgrund: Vi fick under hösten i uppdrag att hjälpa till med en marknadsföringsplan till mikroföretaget Thermo Steel. När vi gick igenom den teori som fanns på området marknadsföring märktes ett stort gap när det gällde marknadsföring för mikroföretag. Det finns ett flertal rapporter som ifrågasätter den traditionella marknadsföringens relevans för mikroföretag. Det motiverade oss att först undersöka hur mikroföretag marknadsför sig och om det finns några generella riktlinjer att följa när det gäller mikroföretags arbete med marknadsföring.Syfte: Med stöd av ovanstående resonemang är syftet med föreliggande uppsats:1. Att undersöka hur mikroföretag marknadsför sig samt om möjligt försöka fastställa några generella rekommendationer när det gäller marknadsföring i mikroföretag.2.
