Most of the saw and pulp industries have stored wood nearby their production, the main reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality. One drawback of wet storage of wood is the leaching of chemical substances into the surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and organic substances. These substances can cause problems for the surrounding environment. The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.

This work of examination describes an environmentally oriented product development aimed to develop new packaging with improved environmental and sale aspects of the products from Primus Sweden AB. The report covers the design process from the first collection of facts to the final results with a description of all methods involved in the work. The focus has been on a clear environmental awareness and the report contains a deepening of the concept life cycle assessment (LCA) for product development. In the process, the consumers? opinions of the brand Primus and environmental profiling formed the basis for the packaging to communicate the right values such as quality, technology, environmental awareness and adventurer?s first choice.The deepening of the life cycle analysis shows that composting and other alternative treatment of the biological cycle is not possible to implement in a satisfactory way in the design process.The work results in two final concepts.

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).

The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores. In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied. Most bacteria need humidity and prefer a quite high water activity to be able to grow.

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..

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

?A culture center should be visually welcoming as well as attract a diverse range of visitors with different backgrounds.? This was the client?s request for a new cultural center in Nairobi. The location is in the heart of Nairobi?s industrial area, near several existing buildings that are already in use by the culture organization known as Go Down. I have chosen to keep most of the existing buildings and to use my new building as a complement for the desired program.

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

Jag har under detta arbete undersökt hur företaget MAD ELF ART kan arbeta med miljö och sociala aspekter i produktionen. Min uppgift har varit att lokalisera en materialleverantör och producent som kan arbeta med detta på bästa sätt.Under arbetets gång har jag kontaktat flera materialleverantörer och producenter och undersökt hur de jobbar med dessa aspekter. Samtidigt har jag även fördjupat mig i hur man kan ta hänsyn till miljö och sociala aspekter i produktionen, för att undersöka hur vi bäst kan arbeta med det.Vad jag kommit fram till är att materialvalet är det viktigaste och det som skiljer en produkt från att vara en miljöbov och en fara för människor till miljövänlig. Därför har jag i bilagan presenterat en leverantör och producent av materialet 100% silke som är ekologiskt färgad och handvävd. Silke lämnar inget energi-fotavtryck och går att återvinna.

The purpose of this study is to give a description of how six pedagogues in the third and fourth grade teaches mathematics and which working methods they use. When using the term working methods it is implied that it can for example be outdoors pedagogic, laboratory material, problem solutions et cetera. This material can both be an everyday material or a pedagogical material. The research was carried through by interviews and observations. Six pedagogues were interviewed in two different districts.

Energi är en resurs som måste användas effektiv för att undvika onödig negativ miljöpåverkan och utgifter. Återmatning från nedåtgående malmtåg till uppåtgående malmtåg leder till en effektivisering i energiutnyttjande. Beräkningen av den återmatade energin utgår ifrån tågets lägesenergi och förlusterna från räls, lutning, vind och kurvor. Totalt kan återmatning av energi ge en besparing på 20 % för enkelspår och 20 % respektive 21 % för dubbelspår. Dubbelspår kan ha mer trafik än enkelspår men förhållandet mellan konsumerad och återmatad energi är i princip den samma.

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.
