Livscykelanalys av en gängtapp - Underlag och verktyg för att inkludera livscykelperspektivet i utvecklingsarbetet vid Dormer Tools AB

The aim of my thesis was to do a Life Cycle Assessment (LCA) of an average thread tap that is manufactured by Dormer Tools AB, and to create a practical model that the company can use in order to study other thread taps from an environmental perspective.The method of LCA is used to investigate the environmental effects of a product during its life cycle. This is a gate-to-grave analysis with focus on steel and thread tap manufacturing, coating procedure, use, waste management and transports. Three common coating types were compared separately. Steel manufacturing answers for the highest energy and raw material consumption under the life cycle of the thread tap. Its emissions contribute to global warming, acidification and eutrophication above others.

Ersättning i praktiken ? I samband med byggandet av Citybanan

Denna studie har utförts i uppdrag av Umeå kommun i syfte att uppfylla det lokala delmålet om en giftfri uppväxt. De vill nu få en uppfattning om hur massagolv kan påverka inomhusmiljön i en förskola, och om dessa golv generellt uppfyller deras policy för materialanvändning. Massagolv är fogfria och porfria golv, de läggs ut som en flytande plastmassa och efter härdning blir de mycket tåliga mot både kemisk och mekanisk belastning. De flesta massagolven baseras på härdplasterna epoxi, akryl och polyuretan. Dessa plaster har olika egenskaper som gör de optimala i olika typer av förhållanden.

Kannibaler och veganer : avstånd och gränsdragningar i köttets värld

There are several ways in which people can relate to eating or not eating animals. This essay is focussing two main strategies: Making distances and drawing borders.Today, there are several reasons for not eating meat, including environmental reasons, individual and public health reasons, ethical reasons and more. Yet, people eat more meat than ever. According to the UN, this is a major problem. In 2006 the report Livestock?s long shadow pointed out that meat consumption was a bigger problem from an environmental point of view, than global transports, including air-traffic.

Lokal logistikoptimering för ENA Energi i Enköping

The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A). The main purpose with this report is to look at three questions: 1. How does the supply chain look today? From forest to industry. 2.

Jämförande kostnadsanalys av retur- och engångsemaballage

This report analyzes disposable packaging and returnable packaging with the methods life cycle analysis and life cycle costs analysis. These two different packaging are analyzed through the company Clas Ohlson?s packaging-flow. To get a picture of how the flow works, a visit at the company and email contact have been done with Clas Ohlson to get relevant informationToday Clas Ohlson has a big flow of articles to the stores without larger variations in the demand, with the exception of autumn, which is when customers start shopping for Christmas. Clas Ohlson?s articles are placed on a pallet and are wrapped into plastic-film for protection and to make sure that nothing will be stolen.

Hållbarhetsredovisning av Teracom enligt GRI - EN 17

Examensarbetet behandlar redovisning av klimatpåverkan från indirekta utsläppskällor hos Teracom AB. Fokus ligger på transporter, som innefattar godstransporter, tjänsteresor och personalens pendling till och från jobbet. Metoden som utvecklats är till för att samla in och behandla data som sedan presenteras i ton koldioxidekvivalenter. Varje del av de ingående områdena har beräknats var för sig med hjälp av i mestadels schabloner. Dessa schabloner har baserats på statistik från Teracoms leverantörer för att de ska stämma överens med verksamhetsområdet och de geografiska förutsättningarna.

Riskhantering i projekt : Modell för uppföljning

In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).

Klimatkalkylering

Detta är en studie om klimatpåverkan i samband med anläggandet av järnvägsbroar i syfte att ta fram nyckeltal (moment, material, mängder) för att effektivt kunna reducera utsläppen av växthusgaser. Till grund för studien har vi arbetat med Trafikverkets verktyg klimatkalkyl 2.0. Det har granskats utifrån användarvänlighet och riktighet i indata och emissionsomräkningsfaktorer. Det för att se till skillnaden mellan modellen och ett unikt anläggningsprojekt, var skiljer sig Trafikverkets typvärden mot de projektspecifika förutsättningarna samt vilka blir dess konsekvenser?Studien har kommit fram till att utan viss försiktighet vid arbete i klimatkalkyl 2.0 finns risk för inkorrekta resultat.

DEHP - från mjukgörare till hormonstörande

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Biogas : En systemanalys av Solna Stads matavfallsprocess

Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.
