Krav på exportlicens vid gränsöverskridande transporter av farligt avfall inom EU
The purpose of this essay is to draw attention to the obstacles that affects the internal trade of waste within the EU. The essay doesn?t in any way encourage pollution or illegal handling of waste but unfortunately there are large profits to be made from illegal destruction and recycling of waste and especially hazardous wastes. Therefore the dependable companies handling waste must access a market with fast and flexible (but predictable) regulations as well as lower transaction costs to help make the environment better and encourage a strive for increased recycling. There are examples where some waste only can be sent to a land-fill within the country but could be recycled in other EU-countries.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work
effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of
the feeding can be very simple or include high degrees of mechanisation.
Three different farms, representing different levels of mechanisation are presented.
Descriptions and analysis of the feeding systems including mechanisation, work effort and
estimations of the feed waste are made on each farm. The herd with the most advanced feed
mechanisation included a rolling feed band and mix wagon. The other farms were partly or
little mechanised including ad lib feeding from big bales and manual distribution of hay and
concentrates.
The most mechanised farm was able to feed a large herd of sheep at a low work effort and
little feed waste. However, the investment in machinery has to be weighed against the
improved efficiency.
Byggnadslogistiskt arbete för minskat slöseri ? En studie över arbetsfördelningen vid innerväggsmontage på Tuve Bygg AB:s projekt Stapelbädden etapp 3
The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.
Utvärdering av miljöarbetet vid nybyggnad av butik : miljöledning och avfallshantering
According to recent statistics the construction industry is responsible for the largest waste discharges of both dangerous and non-dangerous waste, when disregarding the "non-dangerous" amount of granite waste produced by the mining industry and the waste produced by the pulp and paper industry. Preventive work within waste management is an ongoing practice so to be able to reduce negative environmental effects. One of the most common actions for the companies to take is to separate the different kinds of waste from one another at the construction site. Although by working with the problem in earlier stages of the process a large amount of the waste could already have been reduced.Companies in the construction business that are actively working to decrease environmental impact in their operations often use an EMS (Environmental Management System). By using environmental management as method the company can manage their environmental work so that actions can be taken where they are needed the most.
Äntligen kvinnan i centrum! Eller? : En studie av nyandlighet och genus i läroböcker i religionsvetenskap för gymnasiet

The material used in this study consists of five textbooks in religion used for education in upper secondary schools in Sweden. In total, 18 pictures from these books that describe new age, constitutes the subject of analysis. The method used is picture analysis.
Utveckling av substratmixen vid Mosseruds biogasanläggning : Substratkartläggning och rötningsförsök i laboratorieskala
The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.
Undersökning av avfallshanteringssystem : För ett nyexploaterat område i Ekhagen, Jönköping
Outside of many Swedish households today, you will find a typical green wastecontainer. This container has not changed since its introduction, despitecomplaints about foul-smelling and its impractical system. Even if the system usedtoday, still is the most optimal choice, there is a lot of newly developedalternatives out there.Its purpose is to get a broader perspective on how a waste management systemcan be developed into a working, land efficiently and aesthetically pleasing systemof humans and the environment in a small residential area.The authors treat the residential area of Jära, Ekhagen, in Jönköping, which ismanaged by JM AB as a problem area in regards to waste management.The issues raised by the authors are the different waste management systems usedin the corresponding areas of the world, how to apply technical andenvironmental as well as the waste management facilities from financial aspects.In the process, the methods used were literature reviews, case studies and aninterview. The case study was done through a modeling of waste managementsystems in the area Jära and an interview was conducted with the company Envacworking with vacuum systems. Studies have been made by different systems n theareas around the world.The results show that using directives and guidance will reduce the environmentalimpact done without replacing the traditional system.
Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall
Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.
Skillnader i vatten- och avloppshantering inom EU : En jämförelse mellan Slovakien och Sverige
The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).
Kravspecificering av avgaspannor
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.
Kloridutlakning från flygaska : möjligheten till en lokal hantering
In Sweden, there are limits to how much leachable substances waste must contain in order to be deposited as hazardous waste. Fly ash from waste incineration often end up over the limit, mainly due to the chloride content. Fly ash is therefore often deposited abroad. The purpose of this study was to investigate the possibility to handle fly ash locally. To clarify how the law is applied, environmental reports and permit documents from ten waste sites with permission to deposit fly ash were studied.
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.
Analytic Hierarchy Process : en kritisk genomgång
Analytic Hierarchy Process, AHP, är en spridd och mycket omdiskuterad metod för att analysera multikriterieproblem. Syftet med uppsatsen är göra beslutsfattare som använder AHP uppmärksamma på några av de problem som kan finnas med att använda AHP. Uppsatsen redogör detaljerat för hur beslutsfattarens indata behandlas av AHP och visar både med ett konkret exempel och med en formell beskrivning hur en rangordning av alternativ genereras av AHP. Den detaljerade redogörelsen illustrerar att AHP bygger på additiv nyttofunktion vilket döljs för användare av programvaror utvecklade för AHP. Vidare belyses andra drag i AHPs behandling av indata, drag som i flera fall döljs för användaren..
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.
