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.
Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun
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.
Jämförelsestudier av Takkonstruktioner med Stora Spännvidder
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
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.
Från spill till produkt
Detta arbete har sin utgångspunkt i ökad återvinning och minskning av sopberg. Ett exempel som vi har använt oss av i vår forskning är ett samarbete mellan Röda Korset och Kriminalvården. Varje år slängs 25 % av de textilier som välgörenhetsorganisationer får in och dessa sopberg skulle man kunna minska genom ökad återvinning. Kriminalvården har registrerat ett varumärke som heter Made in Jail, vilka tillverkar köksrelaterade produkter. Syftet med det här arbetet blev därför att utveckla idéer till hantverksprodukter som slukar mycket spill.Valet av metod blev kvalitativa intervjuer, som utfördes med tre personer med olika kopplingar till arbetet.

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..
Bildernas byggstenar : En studie om pixlar och vektorers egenskaper i form av digitala material
With a new digital world that runs parallel with our physical one, we are also facing a new type of architecture and new materials that this new architecture is built on. In this thesis I examine pixels and vectors, two of the digital materials used to create pictures. By approaching them as digital materials, I have mapped their different qualities, when and where one or the other is more or less applicable and the reason behind it. My main research question asked was the following: Are the (digital) materials challenged outside their primary fields of application, and in that case, in which way? With this question in mind, I carried out a semiotic picture analysis on four pictures, later on dividing them into four different categories, based on their different qualities and their ability to deliver information.
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.
Landet lagom och dess "lagomläromedel" : Om jämställdhet och genus i grundskolans läroplaner och läromedel från olika årtionden
The purpose of this study is to examine two educational materials from different decades, to see if they have a conscious gender and equality perspective, and to see if they have followed the development society made regarding gender and equality. Even the curricula have a part in my study as I will relate them to the educational materials. Equality as a concept means briefly that women and men should have the same conditions, and gender depicts our notions of femininity and masculinity.I have chosen to do textual analyses, focusing on multimodal discourse because I analyze both text and image. I also use both quantitative and qualitative methods.My questions are: In which way do the curricula and the educational materials express equality?; In which way do the curricula and the educational materials express gender?; Do the educational materials express the fundamental values written about equality and gender in the curricula? And, if this is the case, does it mean that educational materials have followed the development of the Swedish society?The conclusion of this work is that equality and gender are presented as goals in both curricula, but the new curricula have developed that section more.
Barns tankar kring sopor : Hur arbetar förskollärare med ämnet?
The purpose of this analysis was by qualitative semi-structured interviews with twelve children 5-years old and six pre-school teachers at three pre-schools, a total of six departments, find out how pre-school teachers worked with waste separation, if it motivated the children to take care of the environment, and if the work was understandable for the children. The results showed that the children did not comprehend what the pre-school teachers expressed that they worked with regarding waste separation and actions connected to caring for the environment. The pre-school teachers also expressed that the children was not mature enough to learn about the process when waste separated garbage is recycled, and that the work with the subject therefore had been carried out on a lower level. The children however expressed knowledge that did not come straight from their actual every day life, but since dialogue about the subject did not seem to exist between pre-school teachers and children, the pre-school teachers appeared to have failed in making the learning meaningful and understandable for the children, from their knowledge, experiences and interests..
Klagomålshantering i den svenska bankbranschen
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.
