Avklassificering av avfall - End of Waste. En tillämpad studie av teoretiska förutsättningar och praktiska förväntningar på avklassificeringsbestämmelsen i 2008 års ramdirektiv om avfall

Avfallslagstiftningen innebär hanteringsbegränsningar och myndighetskontroll i syfte att motverka de miljörisker som avfallet innebär. Efter ett återvinningsförfarande kan den börda som avfallslagstiftningen innebär upplevas tung för återvinningsbranschen att bära i förhållande till de risker som de återvunna materialen utgör. Därutöver anses avfallsstämpeln i sig ha en hämmande inverkan på användandet av återvunnet material då den resulterar i negativa associationer. Det aktualiserar frågan kring när avfall juridiskt sett ska upphöra att vara avfall (avklassificering av avfall). Frågan kring avklassificering av avfall har under lång tid varit oreglerad inom EU och de få riktlinjer som funnits har härrört från ofullständig EG-rättslig praxis.

Borrning och gängning av laxkilar till vågkraftverk med industrirobot

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

Älgexplosionen på 70- och 80-talet, ett hot mot sågverket?

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

Bygg- och rivningsavfall- Hanteras kakel och klinker på rätt sätt?

Inom byggbranschen omsätts stora mängder byggavfall. Avfallet är svårt att hantera för attdet består av så stora mängder. Restavfall som kommer från en byggarbetsplats källsorteras.Avfall från byggnation och rivning innehåller många olika typer av miljöfarliga ämnen,vilket förorsakar miljöföroreningar. Farliga ämnen riskerar att läcka ut i marken och ut inaturen.Branschen har funderat på om kakel och klinkers verkligen deponeras på rätt sätt idag frånbyggavfall och rivning. Syftet med arbetet var att undersöka om kakel och klinkersinnehåller metaller som kan vara miljöfarliga.

Prevalence of selected infectious diseases in Samoan dogs

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

Gynnar eller motverkar kommunerna kostnadseffektiv miljöstyrning : en studie av kommunala taxor och avgifter

Local charges may induce people to change their pattern of consumption by influencing investments and acts in certain directions. Some charges could for example give people incentives to use less natural resources. This study investigates four different local charges and whether they benefit an economical management with natural resources or not. This is carried out by investigating whether there is a polarity between local charges that may influence environmental actions or goods, and effective pollution control set to achieve certain nationally determined environmental goals. The study includes two economic perspectives and investigates on the one hand whether local charges counteract governmental subsidies and on the other hand whether the charges vary between the different municipalities since large differences may lead to cost inefficiency.

Risker vid kalvutfodring med mjölk från Staphylococcus aureus-infekterade kor

Staphylococcus aureus är både den vanligaste mastitorsakande bakterien hos svenska mjölkkor och den bakterie som orsakar flest matförgiftningsutbrott hos människa världen över. Utveckling av tekniker som möjliggör subtypning och genkaraktärisering av S. aureus-isolat har möjliggjort stora framsteg inom S. aureus-epidemiologin på senare år. I Sverige är det mycket vanligt att kalvar utfodras med mjölk som kan innehålla S.

At the bottom of the screw conveyer and the inlet feeder there is a bearing that keep the parts together. However the lubrication of the bearing must be made manually.

Buntning av grot med lastbilsmonterad utrustning :

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

Analys och organisering av ö-drift för en samförbränningsstation vid Åmotsfors bruk

Åmotfors Bruk AB (ÅBAB) has today an inefficient production of steam for the manufacturing of paper. Unpredictable energy prices and modernisation of the current equipment has been the underlying factors to invest in a thermal power plant, mainly driven by garbage. This facility will not only use the steam for paper production, it will also generate electricity through a steam turbine. Today, when a fault on the supplying line occurs which leads to disconnection of the external grid, all the support of electricity to Åmotfors Bruk (ÅB) will disappear. This will lead to major interruptions in the paper production, which will cause severe economical losses.

Embryonal näringsförsörjning hos sandtigerhaj och kortfenad makohaj

In this report female farmers use of technical equipment is investigated. There is little research made on this subject in Sweden, therefore this report can be seen as an explorative study. Research makes it clear that machinery, throughout history and even today, has been seen as a male area. Heavy machines are often associated with the same attributes as masculinity. Force, power, efficiency and control are some examples.
