?R KUSTN?RA ALK?RR I BOHUSL?N ETT ?BLUE CARBON? HABITAT?

In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Hur påverkar förtätningen stadens grönstruktur? :

Urban density is not new, but rather one side of the continous processes of change underway in the city. During the urbanizing boom of the industrialization, when the cities grew bigger, the first spaces to be built on were vacant and planted areas in the interior of the district. The gardens that once were there were replaced by yardhouses. The idea of urban density is that a dense city means less distance between residential areas and workplaces, resulting in fewer shipments and travelers, which ultimately leads to lower energy consumption and lower emissions. Urban density may lead to shorter distances, but not necessarily. In the wake of urban density the greenstructures of the city is shattered. The possibilities for green areas to contribute to the health of the city and its inhabitants is dramatically reduced.

Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor

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.

Regeringens reglering av hållbarhetsredovisning : En tvärsnittsstudie av hur fyra företag inom energibranschen kan påverkas

Bakgrund: I Sverige ska de statligt ägda bolagen från och med den första januari 2008, upprätta en hållbarhetsredovisning. Motsvarande skyldighet finns inte för icke-reglerade bolag, dessa kan dock frivilligt välja att presentera hållbarhetsinformation. Institutionell teori menar att organisationer inom en institution efterliknar varandra som ett reslutat av samhällets påtryckningar. Regeringens riktlinjer gällande en obligatorisk hållbarhetsredovisning för statliga bolag skulle på så sätt kunna resultera i en indirekt reglering av de icke-reglerade företagen. De undersökta bolagen i denna studie är det statliga bolaget Vattenfall AB samt de icke-reglerade bolagen E.ON Sverige AB, Tekniska Verken i Linköping AB och Mälarenergi AB.Syfte: Syftet med uppsatsen är att undersöka huruvida de fyra undersökningsföretagen kan ha påverkats av Regeringens riktlinjer för en obligatorisk hållbarhetsredovisning för statliga bolag.

Val av energisystem för en hållbar stadsdel : En fallstudie av Östra Sala backe

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

"What is it like to be one of these people?" : Narrativa strategier för att skapa inlevelse i reportage

The eyewitnessed reportage has a pronounced character of narrating. The imaginative power of the text helps the reader to empathise with the characters. That makes constructing empathy a necessary skill of reporters. But how can this be done?Despite a tradition of story telling among reporters, narratologists virtually have neglected the reportage genre.

Rötning av matavfall ? en studie av metanutbytet hos matavfall förbehandlat med skruvkrossteknik samt vid samrötning med bioslam från pappersbruk

Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.

3D-modellen som kommunikationsverktyg

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Karaktärisering av avfallsbränslen

All products will eventually end up as waste, which in a sustainable society has to be handled in an efficient and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed.The study concerns the region of Borås, Sweden, where the waste plant Sobacken has provided a good starting point. On this site, fuel to the Energy-from-Waste plant of Borås Energi is prepared and the biological waste is treated through anaerobic digestion.One important part of the study has been to collect experience-based knowledge from the technical staff at Sobacken and Borås Energi. This information was compiled into an overview of wanted and unwanted fractions to the preparation plant and the boilers respectively.

Användning av svenska stiftelser i fåmansföretagskonstruktioner

Denna uppsats syftar till att utreda huruvida ändamålet med fåmansföretagsreglerna kan kringgås genom företagskonstruktioner med svenska stiftelser. I utredningen läggs fokus på fåmansföretagsreglerna samt de regler som behandlar kontrollmöjligheten av en stiftelse. Även de skattemässiga konsekvenser som medförs i en fåmansföretagskonstruktion med en svensk stiftelse behandlas.Syftet med fåmansföretagsreglerna är att motverka att en delägares inkomst som härstam-mar från arbetsinsats i företaget omvandlas till kapitalinkomst. Om en utomstående, direkt eller indirekt, i betydande omfattning äger andel i ett företag eller direkt eller indirekt har rätt till utdelning, tillämpas utomståenderegeln som är en undantagsregel från fåmansföre-tagsreglerna. Tidigare lagstiftning har inneburit att utomståenderegeln har kunnat tillämpats vid ett indirekt ägande.
