Materialavfall som resurs : En studie av hur man samarbetar i en region fo?r ha?llbar utveckling

The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.

MATSVINN FÖRSVINN - En kvantitativ studie om hur ett CSR-argument kan involvera konsumenten i kampen mot matsvinn i butik

Every year 67000 tons of food is wasted by Swedish retail stores. The waste implies financial losses for the retailer and it has a huge impact on the global environment. Reducing in-store food waste is thus a win-win situation for both retailers and society. The most effective way to reduce waste is primarily by optimizing the logistics of supply, but customers expect a store with a wide range of products and stuffed shelves. Thus there will always be products about to expire.

Effektivare elanvändning på avfallskraftvärmeverk : Förslag till handlingsplan för minskad elanvändning på Renovas anläggning i Göteborg

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

Från konflikter till ett gott samarbete. En fokusgruppsstudie av familjerättssekreterares syn på små barns boende vid föräldrarnas separation.

Syftet med uppsatsen var att undersöka familjerättssekreterarnas syn på små barns (0-3 år) anknytning till föräldrarna då dessa separerar samt hur familjerättssekreterarna arbetar kring detta. Undersökningen tog formen av en fokusgruppsintervju med en arbetsgrupp vid en familjerätt i södra Sverige. Resultatet visar att deltagarna anser att det finns en ny ung föräldragrupp som har ett starkt rättviseperspektiv och därför vill dela barnen lika vid en separation. Följderna av ett tidigt växelvis boende är ännu inte belagda, vilket gör det svårt för familjerättssekreterarna att ha en tydlig ståndpunkt i frågan då de möter klienter eller skriver utredningar till tingsrätten..

Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Människan, kalven eller gödselbrunnen? Mjölkens destination och fördelning - hos mjölkbonden

A variety of food is produced and passes the whole chain by processing, transport and trade and finally it ends up with the consumer. But in many cases, the food is disposed before it is eaten. Some of the produced food does not even pass the whole entire chain before it turns to waste. The question about food waste in debates is a case of access to food for every human beeing. It is question of consumption of the resources, waste management and an issue of environmental impact.

Fireball 2 : Energieffektiv fiber produktion

The development within the textile industry is always ongoing with development of new andbetter textiles, which often mean the use of non-natural materials like polyester. This doesn?t lineup with the work shared around the world against an improved environment, so the idea came touse a form of linen fibers instead of polyester as the reinforcing material together with cotton.The idea was to use flax, linen of low quality, which is seen as a waste product and garbage inthe production of high quality linen and flax seed oil. This flax of low quality needs to beseparated before it can be used in cotton spinning machines. Fireball 2 is just that, a process toseparate flax fibers through the treatment of a technique called electrohydraulic discharge.The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber.

Separationen mellan stat och kyrka i Sverige : En studie av Socialdemokraternas, Kristdemokraternas och Centerpartiets ställningstagande i frågan

The tradition of a strong church ruling in the Swedish society ages back to the very first start of Christianity reaching the country.  Due to the separation between the church and state in 2000 in Sweden, there have been a lot of changes. No longer would the church be able to influence the politics as it had been able to do before. Since Sweden is a democratic country, the decision had to be made in a voting amongst the parties. The purpose with this paper is to understand the argumentation made by the Swedish parties Socialdemokraterna, Kristdemokraterna and Centerpartiet. This has been made using a text analysis, which studies the argumentations made by the parties in their motions.

Kartläggning av Kassationerpå Bubs Godis

The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.

Identifiering av 13 nya mjölksyrabakterier med DHPLC

Mjölksyrabakterier tillhörande släkten Lactobacillus och Bifidobacterium har nyligen upptäckts hos bin och i honungen de producerar och innefattar 13 nya arter[1]. Forskarna arbetar med att ta fram nya snabba och mer pålitliga identifierings metoder för att karakterisera dessa bakterier. I detta projekt undersöktes möjligheten att identifiera dessa bakterier med en ny metod som heter denaturing high performance liquid chromatography (DHPLC). Metoden bygger på separation av PCR (polymerase chain reaction) amplifierade 16S rDNA fragment i DHPLC [8]. Vid identifiering av bakterier amplifierades olika variabla regioner från 16S rRNA genen, som påvisade efter sekvensering störst genetisk variation mellan dessa bakterier [1]. Separationen utfördes med ion-pair reverse-phase high presure liquid chromatoghaphy (IP RP HPLC) med delvis denaturering av DNA molekylen.

Energy efficient storage of biomass at Vattenfall heat and power plants

Storage of biomass is often associated with problems such as heat development, dry matter losses and reduction of fuel quality. The rise in temperature can potentially cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles can cause health problems in the surrounding. The dry matter losses and reduction of fuel quality can have economical effects. The aim of this thesis project is to develop guidelines on how to store large amount of biomass at Vattenfalls heat and power plants in an optimal way.

Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Barn med separerade föräldrar : En kvalitativ studie om hur förskolepersonalen beskriver sitt bemötande till barnen

Syftet med studie är att undersöka   hur förskolans personal beskriver sitt bemötande till barn med separerade   föräldrar. Genom att intervjua sex pedagoger med utgångspunkt från hela   arbetslaget har vi kunnat skönja personalens bemötande mot barn och   föräldrar. Vi har valt att se på bemötandet genom att använda oss utav   anknytningsteorin. Resultatet visar tendenser på att personalen utgår ifrån   barnets bästa och lyfter situationen när personalen anser att behovet finns,   men även att föräldrarnas handlande i en separation spelar en stor roll för barnens välbefinnande..
