Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process.

Det finns två stationer på Boxholm Stål AB med produktionssågar. Den ena är en bandsåg och två fasmaskiner med hanteringsutrustning för transport mellan såg och fasar samt en automatisk buntmaskin. Fasarna på den stationen är utslitna och håller inte de toleranser som Boxholm Stål AB har på sina produkter. En önskan att kunna planfräsa ändarna har också tillkommit vilket utrustningen i dagsläget inte klarar av. Det innebär att fasarna ska bytas ut.

Äldre fastigheter ger staden ett mångfacetterat uttryck och skapar fysiska kopplingar till historien. De är dock ofta energislukande med dåligt värmeisolerade klimatskal och omoderna installationer. Går det att renovera äldre byggnader så att de blir energisnåla och uppfyller samtidens byggnormer? Innebär en sådan renovering att dess arkitektoniska kvaliteter går förlorade? Uppsatsen utgår ifrån kvarteret Oket som består av olika byggnadsdelar uppförda 1910, 1927, 1938, 1945 och 1970. Byggnaderna inventeras med avseende på konstruktion och arkitektonisk stil.

The aim of this thesis is to examine the theoretical developments on social entrepreneurship. Our purpose is to create a better understanding of the phenomenon leading to new insights. We have categorized the knowledge of the concept into social economy, social ownership, social innovation and social missions. Drawing from our theoretical review we have chosen four empirical illustrations, Grameen Bank, Wikipedia, Basta Arbetskooperativ, Jörn Hälsogemenskap, and we have shown how these fit into the general description of the social entrepreneur. With help of our illustrations we show that it is complicated to pin point the core of social entrepreneurship as they each have separate structures, innovations, social missions and operate close to different sectors.

Dagens ökade miljökrav driver energibolagen till effektivisering av vattenkraftverken. En turbinrenovering är en omfattande process. Vid renoveringen effektiviseras turbinen och behovet av miljöfarliga smörjmedel minimeras. Genom att förse ledskenor med en rostfri motyta möjliggörs användandet av självsmörjande lager, vilket förutom minimering av miljöfarliga smörjmedel, leder till minskat underhållsbehov Målet med det här examensarbetet är att dokumentera och analysera befintligt förfarande vid renovering och uppgradering av ledskenor som ofta blir tidskrävande och komplicerade. Syftet är att presentera en produktionstekniskt förbättrad metod för modifiering av ledskenor.
