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.

Ekonomiska styrmedel för förpackningsavfall : En studie om vad som påverkar återvinningen i EU
In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.
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.
Återanvändning som kommunikativ resurs : En samtalsanalytisk studie av kommunikation med PECS hos en pojke med diagnosen autism
Communicative recycling, to repeat utterances uttered by oneself or others, is a common phenomenon in all societies and languages. The talk of persons with autism often features recycling. The aim of this study was to identify different forms of recycling in communication involving a boy with autism and to describe its functions. Communication between the boy with autism, who used Picture Exchange Communication System (PECS) to communicate, and his parents and teachers was videotaped. The conversations took place in familiar settings, in the boy?s home and at his pre-school.
Återvinningsstationer på Lidingö : attityder och lokalisering
When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.
Återvinning av blandmaterial : Polyamid och Polyester
Om människor fortsätter med det konsumtionsbeteende som råder idag kommer jor-den resurser ta slut. Den fossila råvaran petroleum används vanligtvis vid framställ-ning av polyester och polyamid. Petroleum har en 100 000 årlig process, vilket är en ofantlig skillnad i förhållande till den takt som det förbrukas. Därför har eventuella möjligheter att återskapa en ny filament av återvunnet syntetiskt blandmaterial un-dersökts i detta arbete.Det finns befintliga metoder för att återvinna polyester och polyamid som homogena material. Dock vid återvinning i en gemensam process av materialen får den slutliga produkten en försämrad kvalité.
Askåterföring värt besväret? : en fallstudie av följderna av Stora Ensos försöksverksamhet med askåterföring
This thesis reports on a case study of a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company. The pulp industry which produces the ash, the forest division which would be responsible for identifying land and spreading the ash, and Stora Research, which has had a major part in the design and implementation of research trials. Lacking an overall company decision on ash recycling the matter is left to the individual divisions.
Återvinning av textil
Syftet med rapporten var att studera möjliga återvinningstekniker för Ragn-Sells. För detta användes litteratursökning och intervjuer. Återvinningstekniker som studerats är mekanisk bearbetning, mekanisk återvinning, kemisk återvinning och viskostillverkning. Flera underklasser till dessa metoder studerades också, liksom flera sätt att tillverka återvunna produkter. Rapporten nämner ett urval av återvinningstekniker och försöker inte nämna alla tillgängliga återvinningstekniker.Återvinningsteknikerna har sorterats enligt prioriteringen i EU:s återvinningsdirektiv (2008/98/EG).
Nedskräpade återvinningsstationer - En studie om fördelning av ansvar
In Sweden, responsibility for the collection and recycling of packaging and newspapers lies with the producers. Therefore, the major producers created a jointcollection with 5800 recycling stations. The stations are the responsibility of a coordinating body, Förpacknings och Tidningsinsamlingen (FTI) which ensures Government regulations are adhered to by the producers.In 2006, the Swedish Environmental Protection Agency (EPA) carried out an evaluation of the collection of packaging and newspapers. EPA´s research showedthat 80 percent of households were satisfied with the collection but that there were also shortcomings, including problems with littering at the recycling stations.We have tried to approach the litter issue from different angles in order to suggestpossible measures to reduce the problem. An important aspect proved to be uncertainties regarding the concept of operators.As there are currently many parties involved in the collection process this lead to the issue of who is legally considered as the operator of the recycling stations.
En återvunnen och återanvänd förskola : Hur barn lär sig betydelsen av återvinning och återanvändning
This thesis means to find out how preschool teachers are working to demonstrate the importance of recycling and reuse for children. My hope is to contribute knowledge about various practical methods to establish the idea of sustainable development in the operation. I have used the method of qualitative research and done semi-structured interviews with preschool teachers on certified green flag preschools. The questions I have asked for example concerned how the preschool teachers have worked with recycling and reuse, how much the children have been able to influence and if other didactic subjects are implicated. Six interviews were made and these are summarized in the result part.
Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme
This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.

The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible.
Rening av avloppsvatten efter skärprocess
ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB
Flexible Automation with high-pressure intensifier/pumping technology from
Ingersoll-Rand to provide and continue to develop innovative waterjet cutting
systems for global markets.
The purpose of this assignment is to develop a process water purifier. The
purifier should be applicable as an option to ABB I-R?s production cell
Cutting-Box.
At first hand the process water should be purified well enough to let out in
the municipal sewage system, but the ultimate solution is purifying the process
water to the range that recycling is possible.
When investigating the different principle of purifying water, a research of
different products and their manufactories was done.
These different products were compared and the principle of filtration was the
most applicable, as most of the products were designed for far larger
applications.
As the process water contains quite large amount of particles, it is necessary
to perform the filtration in different steps.
The process water purifier is therefore composed of a module of coarse
filtration and one of micro filtration.
In the module of coarse filtration the mainly amount of fibres and particles
are eliminated. They are kept back in the container unit with the larger
fragments and dumped with these when the container is emptied.
In the module of micro filtration the filtration is performed in two steps.
In the first step particles larger than 50?m are eliminated, in the second step
the micro filter is setting the range of purifying, in this case 10?m.
RA Detect - Antikollisionsskydd förlantbrukssektorn
SecRePac is a household appliance that simplifies sorting of packaging such as milk, juice and yogurt containers. By shredding the packages SecRePac reduces its volume uptake both in the home and at the recycling station. This leads to minimization of both transports to the recycling stations and truck transport for emptying the containers at the recycling station.The greenhouse effect deteriorates and becomes worse and worse leading to extreme climate changes and natural disasters such as floods as an example. Carbon dioxide emissions are the major reason for this and at least 30 percent of all these emissions come directly from transports. In the EU carbon emissions has decreased in the past few years.
