Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.

This study will identify the environmental impact in terms of carbon dioxide for a boiler house on behalf of Kvänum energi. The boiler central consists of a main building, which in turn contains multiple components such as boilers, pipes, etc, the boiler central uses pellets fuel. It also includes a silo and an ash container. The total weight of the boiler is about 63 tons. Each boiler has an output of 600 kW; the central includes three boilers with room for a fourth if necessary.

SammandragDetta examensarbete utförs i samarbete med företaget Componenta Wirsbo AB. Componenta smider detaljer till den tunga fordonsindustrin. Företaget använder sig av sänksmide där materialet formas genom slag från två rörliga verktyg. Smitt material har mycket goda hållfasthets egenskaper samt en mycket homogen struktur.Företaget har som miljömål att minska sin uppvärmningsenergi med 5 %. Componenta arbetar även med ett Leanprojekt som ska leda till en mer kontinuerlig produktion.

SummaryAt the summer festivals and it?s campsites there are each year thousands of tents left behind. Last year, at the Peace and Love festival in Borlänge, 220 tons of garbage was left behind at the festival area, much of which is tents. 69% of festival goers have at some point left behind a tent on a festival campsite. Many of these tents is purchased very cheaply, for a single festival.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Kalmarhem AB har uppmärksammat att det existerar ett ohållbart beteendemönster bland hyresgästerna inom studentgruppen. För att kunna bryta detta mönster avser vi att genom denna uppsats  utreda vilka attityder och beteenden som existerar bland hyresgästerna samt ge förslag på förändringar som företaget kan genomföra för att skapa en positiv beteendeförändring.Vi avser att lyfta fram vilka åtgärder som är mest lämpliga att använda av bostadsföretag för att motivera studenter till att agera mer miljömedvetet i hemmet. För att utveckla effektiva marknadsföringsåtgärder valde vi att utreda vilka attityder som råder och hur de förhåller sig till det aktuella beteendet.Vi har använt oss av en abduktiv ansats där vi utgått  från vår fallstudie av Kalmarhem AB. Vi har använt oss av både kvalitativa och kvantitativa undersökningsmetoder i form av en enkätundersökning, fokusgrupper, panelintervjuer, en telefonintervju och en gruppintervju samt observation för att insamla nödvändig data.För att erhålla större förståelse för ämnet presenterar vi i referensramen de olika teorier och begrepp som ligger till grund för vår uppsats. Vi presenterar även den forskningsmodell vi utgått från i våra empiriska undersökningar.Vi kunde konstatera att problemet med bristfällig källsortering inte härstammar från negativa attityder gentemot miljöansvar, med andra ord såg vi ett svagt samband mellan beteende och attityd.

The purpose of this study is to facilitate sustainable building by the use of BIM. The goal is to determine which aspects of sustainable building, which can be analyzed mainly with BIM tools, but also other aids.The study is based on literature studies and interviews. The literature review examines aspects important for sustainable building by studying environmental certification systems applicable in Sweden, as well as the BIM tools available on the market to analyze these aspects. The literature also includes the concepts of BIM and sustainability in order to provide a clearer view of its meaning. The interviews have brought the study's overall understanding of the industry and guidance on the subject.The results are presented in a table, where the aspects relevant to sustainable building are listed.

Varje år uppkommer det stora volymer av jord- och bergmassor vid jord och schaktarbeten. Dessa massor måste hanteras, ofta körs de iväg till deponering och ersätts med nytt material. Det finns inga exakta siffror på hur stora massor det rör sig om. Men uppskattningsvis så kör var fjärde lastbil i Stockholms län omkring med jord- och bergmassor på sin last, detta är både kostsamt och resurskrävande. Förr fanns det upplag och täkter centralt, men i och med förtätningen av Stockholm flyttas dessa längre och längre bort från byggnationerna, med resultatet att transporterna blir dyrare, samtidigt som det sker en långsam utarmning av jord- och bergresurserna.

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.

During the spring semester of 2012 did Petra Hollsten independently a thesis on reducing the environmental impact of capsule for coffee, tea and chocolate. The work was performed at Karlstad University, Faculty of Technology and Science under the Bachelor of Science program in innovation, technology and design. The project's scope is at 22.5 points.The employment for this project is the company Löfbergs Lila AB in Karlstad. Supervisor at the Principal has been Maria Herou Wallner and Sandra Lyxell, product managers. Supervisor at Karlstad University is Monica Jakobsson, lecturer and program leader for innovation and design engineering program.

I samband med att konsumtionen av kläder och textilier ökar i världen slängs också allt mer kläder i hushållssoporna. Studier visar att den genomsnittliga svensken köper cirka 15 kg kläder varje år varav hela 8 kg hamnar i soporna. Endast 20 % av det totala textila avfallet återvinns. Trots att återvinning av textilier visat sig ha mer miljönytta än till exempel återvinning av tidningspapper så finns i dagsläget inget producentansvar för textilbranschen, vilket gör att all insamling av textilier sker på frivillig basis genom bland annat välgörenhetsorganisationer. Oavsett om ett producentansvar kommer att införas för branschen i framtiden eller inte krävs att samtliga parter, både konsument och producent engagerar sig i processen för att insamlingen ska fungera.

AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.

At the moment in central Täby there are small district heating network operated by Fortum Heat. The distribution network has an annual heat demand of about 70 GWh, which is supported by the network's two plants, Galten and Farmen. Täby as a region is rapidly growing and there are grand plans to develop the area. Estimated market potential for a future district heating expansion in Täby is very high and as early as in 2007 Täby decided to invest in a large-scale expansion. In autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to find a partner that could implement those expansion plans. To secure a cheap basic production the partner also need to build a power plant at Hagby recycling center. Despite high interest during initial state of the process, only one procurement offer were received and Täby suspended the contract in March the following year.
