Analys av framtidens system för hantering av avloppsvatten och matavfall i Eskilstuna
Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.
Humanurin till åkermark och grönytor : avsättning och organisation i Göteborgsområdet
This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.
Återanvändning - Sättet att ge hemelektronik ett andra liv
Increased consciousness about environmental and sustainable issues has led to consumers and companies who are more in favor of reuse and recycle. Even though this is a fact, people today are buying new things more often compared to before. For instance for a mobile phone the functionality lifecycle is eight years which can be related to the economic lifecycle today which is 1.5 years compared to 3 years in 1995. Only 1-2 percent of the mobile phones thrown away in Sweden today are handed in for recycling. The purpose of this study is to investigate whether an international company within the recycling and reuse of mobile phone industry has a market in Sweden.
En jämförelse av Sveriges och Storbritanniens producentansvar för förpackningar :
The purpose of the thesis is to compare Sweden's and Great Britain's total costs for their systems regulating producer responsibility for waste packages. Producer resonsibility is a strategy implying that producers are responsible for their waste also after its use. Sweden and Great Britain introduced different systems systems after an EU directive was adopted in 1994 (94/62/EC), and they have resulted in entirely different recycling levels in the two countries.
In the Swedish system, responsibility has been delegated to the industry who are responsible for reaching the determined goals. The economic instrument used is a fee, set and managed by the industry. The British system is more centrilised, and the economic instrument used to finance recycling of waste is a system based on transferable permits.
The thesis compares the four different alternatives: delegated and centralised methods, and fees and transferable permits analytically.
Information overload? En kritisk begreppsanalys
Information overload is by no means a new concept, but has come to prominence the last decade. A generally accepted definition of the phenomenon does not exist. The main question in this master thesis is how to define information overload in order to create a connotative concept for information science. This thesis reviews the nature and causes of information overload, and considers possible solutions, both individual and technical, and their relevance to the information professional. The review of the results shows that researchers seldom or never give a legible definition of what the concept information holds.
Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme
This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.
Jewellery in the logic dreams - på jakt efter drömkänslan i konsten
Nina Johansson starts her essay by making some examples of dreams to show the diversity of the ?dream world?. She speaks of how all humans dream, that it ties us together.

Problemidentifiering vid införandet av ett tågprojekt - En fallstudie för Stena Recycling AB
Stena Recycling AB använder sig i dagsläget av både externa lastbils- och interna tågtransporter i Norrland för att frakta material söderut. Företagets vision är att minska andelen lastbilar till förmån för tågen både av kostnads-, konkurrens- och miljöskäl. Studien har genomförts eftersom tågen nu utnyttjas till 90 procent och företaget vill använda dess maximala kapacitet. Det material som är tänkt att fraktas med det lediga tågutrymmet går i dagsläget med externa lastbilstransporter. Det är ur ett helhetsperspektiv vi vill undersöka lönsamheten samt kartlägga tänkbara problem som Stena Recycling AB står inför, när de vill överföra delar av sina vägtransporter till en intermodal lösning.
Undersökning av avfallshantering i Stockholms innerstad
According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.
Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen
The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.
Levande Skogsbruk : om problem i ett naturvårdsärende
In this study, some aspects of communication that are creating problems in a
chosen forest conservation case are explored. Focus is on how the manager of a
forest experience how he is treated during a formal decision of conservation.
The paper also gives introduction to communication theory as well as to
present forest policies in Sweden. Explanations of the most common concepts
and terms in forest conservation is presented and such a understanding is necessary if the reader is to acquire enlightment from the material and the following
discussion.
This paper focus on a conflict between the county administrative board, a
Swedish regional authority, and a private forest-manager. This is a case where
the manager feels that the authority is forcing a sale of land, because the forest
is being turned into a conservation area. The problems are not just economical,
the manager feels mistreated and left out of the discussion, and the negotiation
is long and problematic as shown in the interview and the case study.
In the study, an in-depth interview is made with the manager of the forest,
and a case study has been made based on the documents in the case attained
from the county administrative board.
Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun
Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.
Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam
In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status.
The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.
Statens rätt i konkurs : Lika rätt för borgenärerna?
This essay is questioning if the state as an unsecured creditor in a bankruptcy proceeding, according to the principle of equal treatment, has the same rights as the other unsecured creditors. The principle of equal treatment means that creditors with unsecured claims are supposed to have mutually equal rights to dividends in a bankruptcy. In the Swedish bankruptcy law from 1987 there are recycling rules which means that some legal actions taken by the bankrupt debtor before the bankruptcy can be recycled to the bankruptcy estate. These rules do not apply on taxes. This essay analyzes whether the state should have this advantage or not.
