Miljöbedömning av olika behandlingsmetoder för organiskt hushållsavfall, slakteriavfall och flytgödsel

Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household waste, slaughterhouse waste and liquid manure. Other than biogas production, the possible treatments for organic household waste and slaughterhouse waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

Opera i Stockholm, Frihamnen

Operabyggnaden placeras längst ut på piren och tar hela dess udde i anspråk. Operan riktar sig mot staden. Byggnadens storlek och koncept kräver viss rymd och ljus runt sig varför valet av plats blev naturligt. Den stora operavolymen skärs itu i flera delar och de olika volymerna binds sedan samman av en stålkonstruktion som på vissa ställen fungerar som ett orangeri medan den på andra ställen är en öppen pergolastruktur. Växtligheten används som ett material och ger intressanta rum, skuggspel och klimat. Orangeriet/pergolan löper igenom och runt byggnaden och såväl personal som besökare rör sig på gångar genom orangeriet/pergolan och upplever olika typer av rum, på olika nivåer. En önskan med uppdelningen i flera volymer är dels för att få in ljus på ett vackert sätt i en annars djup och mörk byggnad, dels för att försöka bryta ner skalan, samt även för att kunna ge personalen bra arbetsmöjligheter.

Från alger till biodiesel - Den italienska drömmen?

This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

Bearbetning av befintligt bostadsprojekt med syfte att uppnå passivhusstandard

I detta examensarbete har energiberäkningar och analyser enligt FEBY12 gjorts på ett radhusområde för att undersöka vad som krävs för att lågenergihusen ska uppnå passivhusstandard. Att uppföra energisnåla byggnader är i dagens samhälle viktigt för alla företag eftersom människor blir allt mer energimedveten och krav från beställare blir allt högre. I arbetet har en modell av radhusområdet modellerats i Revit Architecture för att på ett smidigt sätt få korrekta värden i de olika energiberäkningsprogrammen Vasari, Energihuskalkyl och PHPP. Programmen har helt olika kvalitéer därför har en jämförelse och analys av programmen utförts. Analyser har tydligt visat att det krav som finns för att uppnå passivhusstandard på värmeförlusttalet är betydligt svårare att uppnå än det krav som ställs på den levererade energin. För att uppnå passivhusstandard vidtogs diverse åtgärder såsom U-värde för väggar förbättrades, ventilationsaggregatets verkningsgrad höjdes samt fönsterpartierna reducerades avsevärt.  .

Kan perfluorerade ämnen i kläder bidra till förhöjda halter i reningsverk?

Perfluorinated substances (PF) are environmental pollutants that are used to coat fibres of so called ?all weather clothes? to make them water resistant. PF are effectively spread through water. Waste water treatment plants (WWTPs) are a pollutant source of these substances. PF are poisonous to different kinds of organisms, and supposedly also to human beings, if concentrations are sufficiently high.Perfluorinated substances have been investigated at three waste water treatment plants in Stockholm during the 2000?s.

Metallersättning inom byggbranschen

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

Lönsamheten vid nystart av slaktsvinsproduktion : en fallstudie

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

Temperaturens och den fotosyntetiskt aktiva strålningens effekt på avgång och inlagring av kol på en dikad torvjord

The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. It has earlier been thought that less tilling and higher water table levels would decrease the activity of soil microbes and thereby the decomposition, but recent experiments has showed that this has little or no effect. In this bachelor thesis a field experiment was made on drained peat soil with ley, outside Björklinge, Uppsala municipality, Sweden. The experiment was carried out in May 2011. The objective was to develop a method to examine how the net exchange of carbon diox-ide from plant covered peat soil is affected by temperature and photosynthetically active radiation (PAR).

Studie i att ersätta kärnkraftsreaktor med biobränslealternativ

This report contains a study of replacing nuclear power with biofuel. The nuclear plant, OKG north of Oskarshamn in Sweden has been chosen and an extensive literature study about the nuclear plant has been implemented. The main aspect of this report is the availability of biofuels and whether it would be economically sustainable. Sweden?s most common biofuels are examined with regard to scope of use and potential.

Gud, moder eller mask? : Om konceptuella metaforer i svensk dagspress från Internationella kvinnodagen 2010

This paper is an account of the work around the arrangement and registration of the archive of the Swedish Art-ists? Association?s archive. The Swedish Artists? Association is an association of artists that both makes exhibi-tions for their members? works and handles the Artists? House, called Konstnärshuset in Swedish. During the work with the archive the author faced a number of challenges and problems.

Husen under bron Förskola : Houses Under the Bridge Kindergarden

Kindergarden - How can we create different synergies between different fields that they can benefit from each other? What different activities will suit the kindergarden? How will our perception of the kindergarden, of its need and function in society, change?In this Degree Project in Architecture I will be investigating the combination of the kindergarden together with a restaurant and a dance studio. I believe these activities will harmonize since they have overlapping benefits: We all eat, move and grow.With the new architectural activities in mind, I will further investigate the importance of the kindergarden as a part of society, more specifically our perception of what function it may, may not or could fill. I share the idea with a lot of authors, scientist that we are headed toward a society where children are kept too safe, thus minimising their chance to experience and learn to cope with a harsh reality when they grow up as adults. It's ok to get hurt to an extent, as long as they do not endanger their lives..

H?llbarhetsrapportering i svenska industrif?retag

Sustainability and the role of companies in terms of emissions and environmental impact has become increasingly more relevant. In 2014, the EU decided to introduce the NFRD, a directive that makes it mandatory for companies that meet the requirements to report on sustainability. This thesis aims to examine how four large Swedish industrial companies report about sustainability in connection with the introduction of NFRD, looking at the years 2015 (2014), 2017 and 2022 from an environmental viewpoint. Furthermore, the study also intends to investigate how the companies write about their sustainability work, as actual achievements or what they have ambitions to do in the future. In order to carry out the study, a content analysis with elements of both qualitative and quantitative features has been used called the CONI method.

Utformning av förslag till privatträdgård på Stavstensudde :

In the west part of Trelleborg, on previous farmland a new society is under construction. It is situated right next to the ocean and close to the European freeway. Eight types of villages, all with different kind of architecture will be built in the area, one of them is Torns Village built by Skanska and Ikea. A concept called BoKlok. This specific village consists of twelve houses and five apartment buildings. They are all somewhat classical in their appearance with wooden panel, but at the same time they have a modern touch.

Södra Thailand: Civila samhället - roten till våldet?

Using Varshney's theory about intra- and interethnic networks, this thesis examines how civil society in southern Thailand is built up.During 2004 the violence between Muslims and Buddhists rose in southern Thailand. The government tried to fight the insurgency using violent police and military forces, resulting in hundreds of deaths and part of reason why Thailand is loosing rank in Freedom House's democracy index. Varshney means that a civil society built up on intraethnic networks works favourable to violence between different ethnic groups. Sorting out and defining what is meant by ?ethnic? and ?civil society?, this thesis shows why to look at the insurgency in southern Thailand as an ethnic conflict surviving partly because of an intraethnic civil society.

Åtgärder för biologisk mångfald i parker : Fallstudier i Botkyrka, Haninge och Nynäshamn

Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.
