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.

This thesis is a feasibility study into how Fresenius Kabi may rationalize their destruction process in regards to cost, recycling, and work environment. The two main objectives are to identify scrap flows and the possibility to improve or replace the equipment that is now carrying out the physical scrapping. The flow has been visualized by a flow chart of the material and communication. A chart of the problem established to visualize where improvements are necessary. Based on the problems proposals are presented on how to improve the flow thru the plant.During analyze of the physical scrapping equipment it was also necessary to take a deeper look at how they are carrying out there work today, how does the procedure look like, working environment and where are the weaknesses.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.

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.

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.

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

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.

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.

This master?s thesis was performed during the fall of 2006 at Cloetta Fazer AB in Ljungsbro. Cloetta Fazer is the market leader in Scandinavia of manufacturing confectionary and chocolates. The purpose of the project has been to identify causes that impact the quantity of waste in production as well as a cost/benefit analysis of the solutions that can reduce the problem of production waste.The work includes four production lines that are individually designed depending on what kind of product that are produced on the line. By using qualitative and quantitative methods such as focus groups, interviews and observations data has been collected.

A Swedish company, company F, will establish a new factory in China. Company F is adivision within Company F. The factory in China will manufacture wire products.

A material-balance was analysed according tothe flowchart of the production.

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.

The core process is responsible for internal business development and is the process that runs through the organization and the results which creates a value for the customer. Some research suggests that identification of the client's conscious or unconscious needs clarifying the so-called core process in the organization and operations can thus be more effective. The study aims to identify and analyze the experience of the core process within child health care. The method has been interviews with nine managers and 10 clinic nurses in a county. The results show a lack of knowledge regarding core process and process work.

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.

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.
