jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
… thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C. The purpose of this thesis was to compare pasteurization with …
Solar energy is the one most talked about among energy sources due to its huge potential amongst renewable energy technologies. A greater use of the solar energy may be the solution to today's climate threats. Normally there are two different types of solar technologies, solar …
The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated …
Är det möjligt med biomassa, solenergi och vindkraft?
… planning this house the report also contains a part that deepens in net zero energy buildings. The purpose of the report is to investigate if the house in Borlänge can be constructed to meet net zero energy building demands. Energy efficient houses such as passive- and net zero …
… a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce …

En studie, ur livscykelperspektiv, av energianvändning och växthusgasutsläpp
… one ton of food. The production of these goods requires large amounts of energy and contributes to 22-31 % of all greenhouse gas emissions occurring in Europe. More than one third of the produced food is discarded instead of consumed, and food waste make up about 30 % of the …
… the world. This will be implemented by streamlining and investing in renewable energy. The aim of this degree thesis is to map the usage of energy within production, and also to prepare a method to measure key figures (use of energy per produced unit). The purpose with the …
… that the ewes on most of the farms had sufficient provisions of protein and energy. The most common concentrates were grain mixtures combined with a protein mixture. Today lambs are produced almost the whole year round. What production model that should be used should be based …
… has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket’s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of …
AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with …
1st of may 2003, a new energy system based on electricity certificates, was initiated in Sweden. The purpose with this system, is to stimulate an enlargement of energy production from renewable sources. The electricity system, ist built on that the producers of energy from …
… form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of …
Potential för att minska tomgångsförluster med industriella styrsystem
Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production. This thesis, carried out at Siemens Industry sector, evaluates the potential for using the control system to automatically put machines into energy saving …
… cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for …
