… flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it is released to the recipient. This regulation has not yet been established …
effektivt styrmedel mot koldioxidutsläpp? : En studie av kostnadseffektivitet, transaktionskostnader och teknisk utveckling
Green public procurement (GPP) can be used as an instrument to reduce carbon dioxide emissions, and consideration of environmental aspects within public procurement is becoming more common in Sweden and internationally. Two product groups that have been pointed out as especially …
Oxygen consumption and carbon dioxide production are usual measurements within the sports and training physiology. The same measurements are also common when it comes to establish the amount of energy that is used during work and to establish the intensity of work. The volume of …
… to reduce the impact on the climate. We have calculated the total amount of carbon dioxide and energy use for road models in different traffic classes. To do this we designed a calculation tool that calculates on the total amount of MWh used and the total amount of tons carbon …
vad kommer att hända med morgondagens värld?
… The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular. The world is now aware of the problem and work to mitigate the changes and their effects has begun. The main objective is to significantly reduce global emissions of carbon …
… Several analyses of important parameters i.e. gas production and composition, carbon/nitrogen-ratio, total solids and pH have been performed during and after the digestion tests. The best results (25-28 % methane) were obtained when 5-15 % beets were added to the digester. This …
Kvantitativ undersökning av Kalmar Energis elhandelskunder
… Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this …

… (NSAID) for pain relief, general anaesthesia in the form of carbon, halothane, isoflourane and N2O, local anaesthesia and immunocastration. NSAIDs has been proven to be an effective adjunct to different methods of stunning and has a positive effect post-operative affect, since …
En LCA-analys med fokus på koldioxidutsläpp samt en LCC-analys
… environmental and economic point of view. The life-cycle analysis covers only carbon dioxide emissions, since it is the most spoken of in today’s climate agenda. Furthermore, this study aims to highlight which parts, of the system boundary, that contributes to greater carbon …

… they are time and resource intensive. Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are …
Livscykelanalys av flerfamiljsfastigheten "Teodoliten"
… they are time and resource intensive. Real estate accounts for 15% of global carbon emissions, but also affects our environment in many other aspects. In Sweden this number is even higher. About 30 % of its carbon dioxide emissions originates from building sector and changes are …
… stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial …
… the ice-free season which contributed to elevated amount of available organic carbon to be mineralized to gas during winter. The absence of a fertilization effect in the very high humic lake is most likely due to light-limitation being the key limitator in that lake, thus …
Konceptstudie av ett obemannat flygplan
… plant are the ones that affect the amount of CO2 emission the most. Since carbon fiber has a higher yield strength and a much lower density, the construction doesn’t need as much material. This some what negates the fact that carbon fiber is much more expensive than aluminium …
The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the …
