The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand.

Old industrial sites bear witness of the unsustainable industrial developments in the past. Today many of them stand abandoned and empty, old structures lacking function in our present society. We have in this thesis participated in a visionary student competition arranged by IFLA, International Federation of Landscape Architecture by developing a proposal based on a vision of how Stockholm can stimulate a greener development. We have done this by turning an unsustainable industrial site in the city into an ecological node; Arboretum Lövholmen. Our aim is to develop an entry for IFLA?s visionary student competition by creating a new sustainable design for the industrial area of Lövholmen in Stockholm. We have worked with the following research questions: How can we create a visionary design proposal for Lövholmen that promotes sustainable development with the help of ecological design? How can the competition format be a design tool? How can the working process developing a competition entry progress? The competition demands have shaped our working process and functioned as a platform for the structure of this thesis.

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

Most of the clothes sold in Europe today are produced in developing countries where the production costs are lower. The exploitation of the developing countries has led to that the inferior working conditions in these countries have attracted attention from media and NGOs. Globalisation makes company activities more transparent and the absence of transnational laws calls for alternative regulations. Many companies in Europe has since mid 1990s developed codes of conduct to satisfy the demands of external and internal stakeholders. EU also brought Corporate Social Responsibility to it?s agenda in the beginning of the 2000s and subsequently signals of approaching laws were given.

In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

Problemen med fuktskador i byggnader är många och kostnaderna för att åtgärda problemen är stora. ByggaF är en metod som riktar sig till hela byggprocessen och den dokumenterar, kommunicerar samt säkerställer fuktsäkerheten genom hela den processen. NCC använder sig idag av en egen metod för att säkerställa fuktsäkerheten och den metoden jämförs i detta arbete mot ByggaF. Arbetet inriktar sig mot produktionsskedet av byggprocessen vilket innebär att fuktsäkerhetsarbetet är granskat i det skedet.Syftet med detta examensarbete är att NCC i Umeå ska få en bättre kännedom om vad ByggaF är och hur den metoden kan användas inom byggproduktion. Ytterligare syfte är att visa hur arbetet kan ske för att förebygga fuktskaderisken genom att använda metoden ByggaF, en metod för fuktsäkert byggande.Arbetet är utfört på NCCs byggnation på Öbacka strand etapp 4 och det bygget har fungerat som referens för NCCs fuktarbete.

The Swedish government has a goal of achieving a fossil-free vehicle fleet in 2030. Heavy transport constitutes a significant part of Sweden's transportation sector and the vehicles are driven almost exclusively by fossil fuels. Siemens has developed eHighway, a concept for electric road systems enabling electrification of trucks, in order to reduce the environmental impact of heavy transports. This study aims to investigate the potential that eHighway has on transporting iron ore from the mine of Mertainen to a processing plant in Svappavaara. Electrified trucks are compared with conventional trucks, and diesel and electric trains.The evaluation was made with respect to energy consumption, environmental impact, and cost.

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

Raising pigs in absence of a number of certain diseases is called Seroproduction in Sweden. Internationally it?s called SPF (Specific Pathogen Free) ? Production. It results in higher growth, lower feed consumption, and lower medicine consumption. The pigs are produced under the same concept, but the rules vary a bit between countries.

An increasing global population and a worldwide growing urbanization has raised the questionabout the future food security in cities all over the world. Peak-oil limits the access to cheap fossilfuels which threatens the global food-supply chain. This has resulted in a larger awareness anddiscussion related to urban agriculture. Growing crops and keeping animals within the city-borderscould be one way of creating a more robust and sustainable food supply for city dwellers. However,to enable an expansion of the urban agriculture many theorists argue that policies and institutionalstructures that supports and promotes city farming have to be developed.

Public participation is a key aspect in the planning of Swedish municipalities. It is probably the most important tool of them all in the planning towards a sustainable future within the cities and the municipalities as a whole. Participation from the public can take on several different forms. In this paper I focus to research and discuss in and around the usage of a web-based 3D platform called City Planner. The tool allows the user (the public) to view the municipalities planning in a fairly new (but quickly growing) environment.

By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.

The increased interest in a sustainable environment puts pressure on companies in the manufacturing industry. Rexcell Tissue & Airlaid AB (Rexcell) in Skåpafors produces paper to be converted into tabletop and hygiene products. Rexcell is certified according to the environmental management system ISO 14001, gaining competitive advantages by showing that the company works toward a sustainable environment and that they follow current legislation. The activities at the company are classified as hazardous to the environment according to the Environmental code. Every year, the activities are inspected by an independent inspector.

Sweden?s environmental work is to set out from 16 national environmental quality objectives. It aims to work for a sustainable society and to solve our current environmental problems today and not pass them on to future generations. The purpose of this study was to evaluate Uppföljning av handlingsprogram för miljömål (a follow up-study of a programme for environmental quality objectives) and to propose new methods to work with the revision of Handlingsprogram ? så genomför vi de regionala miljömålen i Hallands län (a programme to implement the regional environmental quality objectives in the County of Halland), a revision which will start in autumn 2010.

The essay examines through semi-structured interviews the experiences of overcrowded housing, as they are portrayed through the eyes of children aged 8 ? 14. Overcrowded housing has an effect on children?s school performance, general health and is often linked to less capacity for normal social consumption. Yet there seems to be little done in terms of interrogating children about how they perceive their situation here and now.
