Samhällsekonomisk analys av ett djupförvar för använt kärnbränsle i Forsmark :
This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark.
Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it.
The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.
Inventering och analys av framkomligheten till Hisingen, GöteborgEn studie på 10-15 års sikt på uppdrag av Ericsson, Volvo Car Corporation och AB Volvo
AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.
Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB
The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Vad är en hållbar produkt? - En studie med svenska klädföretag och organisationer
Miljö och hållbarhet är något som kommit att uppmärksammas allt mer sedan startskottet på 70-talet i samband med ökat fokus från regeringshåll och grundande av miljöorganisationer. I takt med konsumenters ökade medvetenhet har kraven höjts på svenska klädföretag och deras arbete med hållbar utveckling och hållbara produkter. Problematiken ligger i att svenska klädföretag utför sitt arbete på olika sätt och därav finns olika tolkningar av hur en hållbar produkt är framställd och vad denna ska innehålla. Det är även svårt för kunder att få ett grepp av en hållbar produkt, då de inte finns någon konkret definition.Den övergripande problemformuleringen i arbetet har berört hur olika svenska klädföretag och miljöorganisationer definierar en hållbar produkt. I uppsatsen presenteras olika definitioner av hållbar utveckling och den lagstiftning som ligger till grund för de produkter som produceras och säljs på den svenska marknaden.
Beteende på offentliga platser
Several theoretic and environmental psychological models establish a connection between the environment and the reactions of humans and the research support that there is a mutual influence between individual, environmental and behavioral factors. You often assume that a person both can influence and be influenced by the surrounding environment. This is evident, but it is less obvious how a given physical design influence people?s immediate behavior in the city. The aim of this study was to investigate if the physical design of a place influences people in an urban environment and to investigate how the behavior is influenced.
Finansiärer ur ett hållbarhetsperspektiv : En aktörsstudie av Europeiska Investeringsbanken, Nordiska Investeringsbanken och Svensk Exportkredit
Today a major part of the energy produced steams from fossil fuels, finite resources, and a change towards an energy sector based on renewable energy is necessary. Sweden is one of the leading countries with regards to investments in renewable energy but most other countries have a long way to go. This makes it interesting in developing renewable energy projects in new markets in countries like Poland where still a lot of fossil fuel is used. Large infrastructure development projects are very costly and therefore external investors needs to be involved. The investors play an important role in changing the usage of fossil fuels towards renewable energy sources.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
Value Creation Through Corporate Social Responsibility - An illustrative study of five Swedish insurance companies
Corporate Social Responsibility is a concept whereby companies integrate social and environmental concerns into their core business and in their interaction with stakeholders on a voluntarily basis. The purpose with our thesis is to study how Swedish insurance companies work with Corporate Social Responsibility and to analyse the underlying strategies of the companies? social, environmental and economical activities. We will analyse where, how and for whom value can be created with CSR. Where does the value creation take place, how can it be created through these activities and who will benefit from Corporate Social Responsibility? Theories point out that companies need to assemble and value the total package of benefits to be able to create successful corporate initiatives.

Hur hushållas det med mark och vatten? en studie av tillämpningen av hushållningsbestämmelserna i 3 och 4 kap MB
The national spatial planning guidelines
and the subsequent legal regulation
in the Natural Resources Act and the
Environmental Code has been a part of
the Swedish planning system for almost
40 years. In the recent years, critics have
claimed that the regulations are outdated
and does not work the way it was intended.
This paper examines closer why it is
perceived that the regulations does not
work, with a focus on how the national
interests are managed in the municipal
planning. Why is the national interests
not applied in the municipal planning as
intended? Is the error in the system or in the
implementation of it?
The aim of this essay is to study the gap
between theory and practice by studying
how the land management provisions in
the Environmental Code is applied in five
selected municipalities. The aim is also to
find interesting issues for futher studies of
the topic.
Bygg- och rivningsavfall utifrån ett miljöperspektiv : Med fokus på EU:s avfallsmål och en hållbar avfallshantering
The purpose of this report was to identify the current waste management of non-hazardous construction and demolition waste in a few Swedish construction companies, based on the different steps in the waste hierarchy with a focus on waste prevention, reuse and recycle. Additionally, the purpose was to attempt identifying opportunities, obstacles and as well as to propose possible solutions from an environmental perspective. The method used was a qualitative study using interviews conducted through emails and phone with employees occupying positions that could answer this reports questions. The results of this report indicates that waste management of construction and demolition waste has improved, and less waste goes into landfills. The concern is that the overall amount of waste being produced is not decreasing, thus calling for actions preventing the production of waste.
Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern
Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).
Exercise pens as an environmental enrichment for laboratory rabbits
This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.
