Mikroproduktion av solel i flerfamiljshus : Lönsamhetsanalys genom simulering av solcellsanläggningar och explorativ kundundersökning
This thesis is commissioned by the Swedish electricity trading company GodEl with the purpose of evaluate solar electricity in multi-family buildings in the Stockholm region. The prices of solar panels have dropped recently due to the advances in technology, but the installation rate in Sweden remains low. It is therefore interesting to study the profitability of solar electricity today, and if it is profitable enough to install based on profitability alone and not simply due to environmental considerations. Therefore this thesis first studies the profitability of solar panels based on a simulation of electricity production and consumption for multi-family buildings this region. The study concludes that solar electricity can be profitable in the Stockholm region under certain conditions; all of which have to be favourable for profitable solar electricity.The thesis also studies the opinion of the company's costumers concerning solar electricity.

Elproduktion med ORC-teknik ombord på fartygsserien MK II.
Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.
Hastighetsreduktion på genomfartsleder, genom icke-tvingande åtgärder i vägmiljön

The purpose was to portray road environments on thoroughfares in urban areas to motivate motorists to keep the speed limit and thus increase road safety for vulnerable road users. The task question was formulated, how can thoroughfares in suburban settings be portrayed to motivate motorists to reduce speed?
The study was conducted throughout a literature review of motivational speed measures along with interviews with road design experts at the Swedish Transport Administration. Case studies were conducted on three thoroughfares in the Stockholm suburbs Vallentuna, Upplands Väsby and Danderyd.
Finansiella garantier - en möjlighet att säkerställa ett miljömässigt omhändertagande av uttjänta produkter
Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.
Hållbarhetsredovisning inom olje- och gasindustrin : Vilka företagsegenskaper påverkar omfattningen av hållbarhetsredovisning i en miljökänslig industri?
Under de senaste decennierna har CSR uppmärksammats bland företag och samhälle. CSR behandlar aspekter som miljö, samhället och företagsledning. Denna uppståndelse har bidragit till att företag börjat rapportera om dess hållbarhet i årsredovisningar och dessutom i enskilda hållbarhetsredovisningar. Denna rapportering är frivillig i många länder men många företag föredrar att rapportera om detta för att legitimera sig för sina intressenter. Då denna rapportering blivit mycket populär har flera ramverk utvecklats och den mest tillämpade är riktlinjer utfärdade av GRI. Syftet med denna studie är att undersöka vilka företagsekonomiska egenskaper som påverkar omfattning av hållbarhetsredovisning för företag i olje- och gasindustrin.

Indirekt miljöpåverkan inom tjänstesektorn : En intervjustudie om hanteringen av indirekt miljöpåverkan inom några organisationers miljöledningssystem
I och med samhällets utveckling från ett jordbrukssamhälle till ett industriellt samhälle, och vidare till ett tjänste- och kunskapssamhälle har antalet tjänsteföretag växt, och därmed även miljöpåverkan från denna sektor. Tjänstesektorns miljöpåverkan kan delas upp i två delar, en direkt miljöpåverkan kopplat till kontorsverksamheten, såsom energianvändning, samt en indirekt miljöpåverkan, som är ett resultat av tjänstens framtida nytta och bestående värde. Ett vanligt verktyg som svenska företag, och andra typer av organisationer, använder sig av för att strukturera upp sitt miljöarbete är miljöledningssystem enligt den internationella standarden ISO 14001. Miljöledningssystem är dock inte lika vanligt förekommande i tjänstesektorn som inom tillverkningsindustrin. Syftet med denna uppsats är därför att studera hur indirekt miljöpåverkan hanteras, och kan bli mer hanterbart, inom tjänstesektorn.

The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.
Miljöoptimera avfallsindustrin i Sverige : - återvinn restprodukten gips
One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.
