Outnyttjad kreativitet och kompetens inom produktion : - Ett arbete som fokuserar på att fånga upp och ta tillvara på medarbetares kreativitet och kompetens

AbstractResource efficient manufacturing is a term that has been increasingly applied within manufacturing, where one of the key points is to reduce waste of such forms that do not add value for the end customer. By the Lean principles, there are seven plus one types of waste, in which the definition of the eighth point varies among sources. In this study, the eighth type of waste has been interpreted as the untapped creativity and competence among employees that has not been put to use. From this, our question was incubated; How can you make the most of the employees? untapped creativity and potential within manufacturing? The case study will be developed with empirical data obtained from Dometic Group by conducting interviews.From the gathered literature, it was concluded that the communication between employees contributed to an increased understanding of one another as well as it allowed for improvement in work.

Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

Outnyttjade resurser inom park- och naturvård

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Beräkning av miljömässiga och ekonomiska konsekvenser vid källsortering av blandat byggavfall : samt analys av redovisningsmetoder för byggavfallsstatistik

I en värld där människan är det enda djur som lämnar efter sig avfall som inte kan brytas ned naturligt, är det viktigt att avfallet vi producerar tas om hand på bästa möjliga sätt. EU har därför tagit fram en prioriteringsordning för hur avfallet ska behandlas. Denna kallas avfallshierarkin och ska ligga till grund för medlemsländernas lagstiftning om avfallshantering. I Sverige kallas byggsektorn för den ?40-procentiga sektorn? vilket syftar på att 40 procent av Sveriges avfall genereras av denna sektor.

Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.

Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated 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.

Hylshantering samt flödesanalys

Trioplanex International AB is a part of the group Trioplast Industrier AB, which produces packaging materials for the film and hygiene industry. The group is active throughout Europe, where most of the production is located in Sweden, with head office in Smålandsstenar. Operations in Landskrona consist of Trioplanex International AB and Trioplast Landskrona.Semi-finished articles consisting of paper cores, so called bobbins, give rise to a high amount of core waste in any form of core cutting. The objective of the report is to map out all core waste and illustrate the material flow with regard to present layout and equipment.In the beginning of the project an analysis of the current process was carried out with focus on the cutting equipment. A case study in the form of an improvement work took place in order to reduce the causes which had the biggest impact on existing machinery.Improvement proposals were discussed by the author together with supervisor, assigner and other parties involved.

Ekonomiska styrmedel för förpackningsavfall : En studie om vad som påverkar återvinningen i EU

In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.

Spelar kön någon roll? : En studie om kvinnors uppfattning om jämställdhet i World of Warcrafts värld

The object with this bachelor thesis is to illustrate if equality is present during the interaction between female and male players in the World of Warcraft with focus on the female players conception. The main question is: How does gender matter in the interaction between female and male players in WoW? This question is particularly interesting because WoW is in its own construction neutral in regards to gender in the aspect that gender does not hinder or benefit your avatar when it comes to the avatars development or possibilities. This bachelor thesis describes the views three of female WoW players and how they perceive the interaction with male players with focus on equality. The informants? personal thoughts and experiences are described.

Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.

Snille och smak och mord: En litteratursociologisk studie av Nobelpriset och det högkulturella i Karin Alvtegens Skugga

This master thesis deals with the Nobel Prize and highbrow culture as portrayed in Karin Alvtegen?s Skugga. From a sociology of literature perspective, it aims to analyze how these highbrow themes can be understood in relation to Alvtegen?s position in the literary field as a lowbrow crime novelist. The method used is hermeneutic, and the analysis is based on two theoretical models: Pierre Bourdieu?s cultural sociology, and the postmodern tradition where the distinction high/low and its traditional hierarchy is said to be decomposed.

Återföring av växtnäringsämnen från avloppsvatten till åkermark : en bedömning av intresset för nya näringsrika produkter

Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.
