A lot of mine waste rock and tailings arise from all mining processes and have to be stored in an appropriate way. Tailings are deposited in impoundments retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction costs and demand of materials are spread more evenly over the period of deposition.The objective of this thesis has been to compile information about and evaluate events at Swedish tailings dams and also to develop a collective database for all Swedish mining companies for all tailings dams and all events that occur at tailings dams.Information about 60 events at Swedish tailings dams has been gathered and evaluated. The evaluation has been performed by comparison between and analysis of individual parameters and also by use of a multivariate statistical method called PLS.

ADORABLE CHILD OF ITS TIMEThis text will describe a inovative project about material, traditions and someideas about furniture for work in an home inviroment. The content is partlyabout exploring ancient marine- and textile techniques to find somethinguseful for furniture of the twenty first century. It is also about the designprocess of creating a sustainable piece of furniture that questions the paradigmathicsabout usage and the context about manufacturing furniture.The text will briefly describe the design process and then reason about theresult in a deeper sense. Questions that has been considered from the verybeginning of the project as well as those one stumbled across during theevolution of the work will be objectives for the discussion. The result will bein focus as a foundation for the discussion and also the values and issuesabout that.

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

Companies become more and more aware of the added values of the packaging. A well chosen and developed packaging can reduce the costs for the companies through reduced costs for transports, reduced quantity of waste and discards and increased goodwill for example. The companies? costs for salaries can also be reduced due to the increased packaging handling efficiency and the reduced costs for sick leave, reduced work capacity and rehabilitation etc. that can arise when handling poorly developed products and packaging.

The voluntary none-financial sustainability report has become a trend within accounting. The environmental issues used to be driven by activists only, but lately it has moved in to the general agenda in many companies. Investors are starting to put more attention to the sustainability reporting as it is considered to add value to the company. There are several standard guidelines to be used when producing a sustainability report, one example is the GRI´s Guidelines that takes the following three dimensions in consideration: economy, environment and social. This Guideline is from an international perspective considered to be of good accounting practice (Ljungdahl 2008).

To get a good economy on the dairy farms the fertility control of heifers and cows is a crucial factor. It is also important to know which key parameters that should be tracked. In this work well established routines for heat detection have to be applied. When the dairy farmers use technical aid in estrus control it is important not to forget that technical aids can not replace the human eye. Approximately 50 % of all opportunities to inseminate are missed because clear signs of estrus have not been displayed and/or recorded. The cattle fertility has been declining over recent years. During the same time the cow?s proceeds have increased, consequently applying a higher pressure on the cow and the manager.

Today´s debate in farming is being focused on tourism, outdoor life and hobbies in the rural areas. This is of interest also for the general public as a way of counteracting the depopulation of the rural areas. Within the last years, the farming has become more technically advanced and hence efficient. This has led to increased production volumes and wider selection of products with lower margins for the farmer as a consequence. When the profitability is reduced, the farmer is faced with the choice of either increasing efficiency or diversification of the business.

Investment aid is a part of the Rural Area Programme, which contains support to Swedish agriculture and the countryside. There is a new programme every seventh year and SLU (Swedish University of Agriculture) has the mission to perform the evaluation of the previous programme, which lasted between 2000 -2006. The investment aid's aim is to support investments that, among other things, support the adaptation or conversion to more environmentally friendly production methods, improves the product quality, develops new or complementing activities, and improves the environment and the animal- and working environment. The question is if it's only money that matters for these kinds of investments to be done and what has happened with the money that was paid? This thesis investigates how the investment aid has affected the receivers.

Avfallslagstiftningen innebär hanteringsbegränsningar och myndighetskontroll i syfte att motverka de miljörisker som avfallet innebär. Efter ett återvinningsförfarande kan den börda som avfallslagstiftningen innebär upplevas tung för återvinningsbranschen att bära i förhållande till de risker som de återvunna materialen utgör. Därutöver anses avfallsstämpeln i sig ha en hämmande inverkan på användandet av återvunnet material då den resulterar i negativa associationer. Det aktualiserar frågan kring när avfall juridiskt sett ska upphöra att vara avfall (avklassificering av avfall). Frågan kring avklassificering av avfall har under lång tid varit oreglerad inom EU och de få riktlinjer som funnits har härrört från ofullständig EG-rättslig praxis.

At the end of 2008, Arla concluded agreements with several supermarkets in southern Sweden. The agreement with the supermarkets excluded Ska?nemejerier from the stores. This meant that Ska?nemejerier lost approximately 7% of sales volume.

Bakgrund Många mammor som fött barn prematurt önskar amning som uppfödning för sitt barn för bröstmjölkens immunologiska faktorer och som en kompensation för att graviditeten avslutats för tidigt. Amningens etablering kan vara komplicerad och kräva tålamod när barnet behöver vård. Beroende på barnets känslighet kan det ta olika lång tid tills barnet kan påbörja amningsträning. En av de viktigaste faktorerna för att amningen ska kunna etableras är att mamman får igång en tillräcklig mjölkproduktion motsvarande den mängd ett fullgånget barn skulle kräva. För att få igång en tillräcklig produktion är det bra att komma igång med urmjölkning så fort som möjligt efter barnets födelse.

Inom byggbranschen omsätts stora mängder byggavfall. Avfallet är svårt att hantera för attdet består av så stora mängder. Restavfall som kommer från en byggarbetsplats källsorteras.Avfall från byggnation och rivning innehåller många olika typer av miljöfarliga ämnen,vilket förorsakar miljöföroreningar. Farliga ämnen riskerar att läcka ut i marken och ut inaturen.Branschen har funderat på om kakel och klinkers verkligen deponeras på rätt sätt idag frånbyggavfall och rivning. Syftet med arbetet var att undersöka om kakel och klinkersinnehåller metaller som kan vara miljöfarliga.

Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals. The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

In the school political debate that is conducted in Sweden the question of grading is an ongoing topic of discussion. During the past year there has been a lively discussion about introducing grade from year four as suggested by the right wing parties. The purpose of this study is to set the teaching faculties? view and arguments in relation to the politicians' opinion in the ongoing debate about the proposal of introducing grades from year four. Furthermore, the aim is to investigate how central the didactic arguments are in relation to other arguments in the current debate.
