Inventering och karakterisering av brännbart avfall i
Norrköpingsregionen

The purpose of this study has been to make an inventory of combustible waste in the region around Norrköping and to investigate the composition of domestic waste, industrial waste and two different types of sludge. The work was performed at the request of Norrköping Miljö & Energi, due to the planning of an incineration plant. The inventory of the waste was performed through inspection of environmental impact reports, from waste disposal plants in a number of local government areas in the region. The quantities were also compared to another inventory, carried out in a different way. The characterisation of the wastes was compared to the fuel specification determined by Norrköping Miljö & Energi.

Reuse, reduce & recycle : planning for sustainable solid waste management in Stone Town - Zanzibar

In the low-income countries of the world, rapid urbanization and decaying infrastructure results in an increasingly unsustainable situation when it comes to solid waste management. Often, the solution tends to focus on introducing technical advanced interventions based on the conditions of the high-income world. However, this thesis aims to ?nd site-speci?c solutions on solid waste management at a local scale. By taking in consideration of local conditions a customized approach is possible where the solution is not dependent on expensive structural changes.

Med avfall upp till knäna - En osteologisk studie av tafonomi och medeltida avfallshantering i kvarteret Blekhagen i Lund

The subject of this master level thesis in historical osteology, is a study of waste management in the medieval town of Lund. The aims of the study is achieved through looking at the taphonomic aspects of bonefragments from the quarter Blekhagen. The study is divided in two separate sections, one that is a litterature study of what is known about waste management, and another one that contains a taphonomic and spatial analysis. Through examination of the taphonomic variables weathering, average weight and trampling and a spatial analysis, I am able to deduce that there are signs of controlled waste management in the material. It is not possible to draw any general conclusions about waste management in the medieval town however.

Vinster med återvinning, Stena Recycling

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

Vätedriven förbränningsmotor : Klarläggande av framtida hållbarhet

Today when new and harder demands on CO2 emissions are developed, vehicle manufacturers must work to develop new engine solutions to new kinds of fuels to replace fossil fuels. A fuel that could be applied is hydrogen. When hydrogen is combusted only water vapor occurs. Hydrogen is known to be explosive and flammable. These properties are both good and bad for combustion.

Kunskap, attityd och beteende kring hushållsavfall : En jämförelse mellan elever i Göteborg, Sverige och Iloilo City, Filippinerna

Waste management is a major challenge for several countries around the world. Sweden and the Philippines have similar waste management legalization but different potentials to effectively achieve the goal of sustainable waste management. Education is the key to sustainable development and both countries promote the subject environment in the curriculum. Based on scientific articles, reports and personal meetings, a survey was conducted among 510 students from Gothenburg, Sweden and Iloilo City, Philippines. The survey aimed to investigate the knowledge, attitude and behavior regarding waste management and was analyzed to answer questions of possible reasons to differences and also, linkages to sustainable development.

Undersökning av miljöstatusen i Gothemsån / Dalhem i anslutning till utsläpp av lakvatten från sopdeponi i Roma 2010

In October 2010 it was discovered that leach water had been released from a waste deposit directly into a ditch during a period from March until October 2010. The river Dalhemsån runs close to the waste deposit, just about 10 meters from the ditch. By studying the benthic fauna it was discovered that the environmental status of Dalhemsån is bad in this part of the river, but the discharges of leachate from the waste deposit does not seem to have deteriorated the water further since May 2010..

Aktiv ventilstyrning

To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

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.
