This report describes the work of developing a specification of requirements for Waste Heat Recovery Units. The main part of the paper describes how the work with the specification of requirements has been performed. One specific question to be answered is:What are the customer?s demands in case of properties for the Waste Heat Recovery Units and how is that information collected as an order documentation to suit the business area Oil & Gas?The report begins with a description of the assignment and continues with the aim and background. A theoretical part describes the different areas and methods that have been important during the process.
Kompostering av köksavfall och användning av kompost i köksträdgård i Chazuta, Peru : jordförbättring och/eller lösning på ett avfallsproblem?
All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well.
One solution to handle organic waste is to compost, which means a controlled decomposition
of organic waste under aerobic conditions at certain temperatures.
Identifiering av deponerat material i en deponi samt metodikförslag för upprättande av vattenbalans.
Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.
Reducering av kassationer på Cloetta Fazer AB
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.
Val av komplementmaterial för våtkompostering av klosettvatten
Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.
Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam
Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.
Slöserijakt i betongdjungeln : En tidseffektivisering av monteringsprocessen inom stål- och betongprefab
The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Resurseffektiv livsmedelsproduktion : Tillämpning av industriell symbios för ökad resurseffektivitet inom den svenska tomatodlingsbranschen
Industries with energy costs as a large proportion of their total costs are greatly affected by the instruments deployed to cope with the Swedish climate and energy policy goals. With energy costs representing more than 30 % of the total costs, tomato cultivators are one of the affected industries. In order to remain competitive with other countries, a more resource- and cost-efficient cultivation of tomatoes in greenhouses is desirable in Sweden. Based on the concept of industrial symbiosis, this study investigates the prerequisites for a resource-efficient production of locally grown tomatoes in Sweden through the utilization of low grade industrial waste heat. The study is based on the foundry industry as the supplier of waste heat.To investigate the environmental, technical and economic potential of the exchange of waste heat, a comparative life cycle assessment, an inventory of the supply of industrial waste heat in Sweden, a compilation of potential technologies for the recovery of low grade industrial waste heat for heating greenhouses and a comparative life-cycle cost calculation were carried out.
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.
Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping
This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.

Hållbar utveckling är en vision som hela världen eftersträvar att uppnå. Hushållsavfallshanter-ing är ett sätt för att uppnå en hållbar samhällsutveckling. Bra kunskap, information och sam-verkan mellan olika aktörer är ytterst nödvändigt för att kunna uppnå en hållbar samhällsut-veckling. Syftet med fallstudiet är att kartlägga en del av stadsdelen Augustenborg i Malmö för att se över hur hushållsavfallshantering fortskrider. Det är även vårt syfte att identifiera möjligheter och hinder för en ökad källsortering i området.
Återvinning av dryckeskartonger : En studie som syftar till att öka återvinningsgraden av Tetra Paks förpackningar i Indonesien
People of the modern world consume more than they ever used to do. Because of the close correlation between consumption and the amount of waste, the waste volume is also expected to increase. The purpose of this study is to examine if some measures in the recycling process from Sweden could be implemented in Indonesia. In fact, Indonesia is one of the countries in which the waste management system is struggling. Tetra Pak, one of the world leading producer of food packaging, is studied in this report.
Avfallsdirektivets påverkan på efterbehandling av förorenad mark
The purpose of this report is to increase the awareness about the problem that occur when the waste hierarchy is applied to management of contaminated land. The work with remediation of contaminated land in Sweden is part of the efforts towards reaching the national environmental objectives. Therefore a subsidiary aim is to analyze how this influences the prospects of reaching the objectives. The work consists of two parts; a case study and a comparative literature study that focus on England, the Netherlands and Sweden. The case study is intended to provide a practical perspective through a comparison of the climate impact from two methods.
