Abstract:

The need for energy and fuels is predicted to grow within the next decades, in parallel to the need of decreasing the emissions to air and water to operate within the planetary boundaries. The alternatives to consider as energy or fuel options need to be environmentally friendly, evaluated over the whole life cycle. Hydrogen is one of the considered alternatives because it contains no carbon and has a good environmental performance when produced from renewable sources. It can be produced by a variety of methods, where electrolyzers have a good potential environmental impact if powered by renew

Abstract:

This master thesis investigated the influence of prefabrication rate of buildings on the embodied environmental impacts. Through a comparative attributional LCA four different Swedish buildings were investigated to explore the influence of PR on the environmental impacts in the categories Cumulative Energy Demand, Global Warming Potential, Water Consumption, Fossil Resource Scarcity, and Mineral Resource Scarcity. The reference buildings had prefabricated rates of 14, 26, 38 and 91%. The results indicate that a higher prefabricated rate (PR) can lead to a lower impact in these categories to so

Abstract:

In this thesis a future-world case was undertaken of the life cycle assessment (from cradleto grave) of a single-family house. The house is expected to be constructed by the end of2021 in Borlänge, a city located in Dalarna County. The aim of this study is to investigatewhether the building materials in external walls and roof surpass in terms ofenvironmental impacts compared with other building materials suggested by the authorsof this thesis.Six scenarios were evaluated in terms of the environmental impacts for two buildingelements, external wall, and roof. A base case scenario is taken into

Abstract:

The ever-increasing awareness of global warming has made the building industry startlooking for alternative building solutions in order to meet the changing demands. Thesechallenges have given rise to organization which aim to go further and construct moresustainable alternatives in the form of Ecovillages. This thesis is conducted in collaborationwith Bysjöstrans Ekoby and aims to investigate what type of organic alternatives exist andhow they perform in building elements.The study was carried out through a comparative LCA where a base case construction forboth roof and wall was established.

Abstract:

During the last decades the challenge of sustainability has become more urgent and environmental impacts of different processes in manufacturing industry have received more attention. Life cycle assessment (LCA) has become an important and useful tool to evaluate the environmental impact of products and processes. In this study the environmental impact of two cooling techniques in a turning process has been evaluated using LCA. Turning is used for shaping metal parts by removing material. The compared cooling techniques in this study are dry cutting and Minimum Quantity Lubrication (MQL). The

Abstract:

Globally, there are approximately 900 000 telecommunication radio base station sites (RBS-sites)located in areas without access to the electrical grid. Traditionally, these sites are powered by dieselgenerators, consuming large amounts of fossil diesel fuel. Diesel combustion is connected both toenvironmental impacts and high economical expenses for the mobile operators. As the mobilenetwork expansion is increasingly located in off-grid areas of developing countries, the search forrenewable power alternatives has been intensified. This Master thesis presents results from a life cycle assessmen

Abstract:

Worldwide there is an increasing demand of natural resources. In future, non renewable resources get substituted by renewable resources in the energetic sector as well as in the material sector. That implies a stronger usage of renewable resources especially - wood. In 2009 there was a usage of 77 million cubic meters of wood for material applications and a quantity of 55 million cubic meters for energetic applications in Germany alone. Furthermore, there is an increasing demand on wood for energetic purposes. In 2007 this problematic development led to the first supply bottlenecks. To meet th

Abstract:

A wide variety of assessment techniques are presently available to quantify the environmental performance of an organisation. They are predominantly site- or area-specific, making them sensitive to differences in the environmental capacity of an area, and they exclude a number of global impacts. A more generic level-plane assessment tool, which quantifies the environmental burden, may therefore be needed to make a valid comparison between organisations. Furthermore, the generic process data used in these assessment tools, to inform policy decisions on a material or product, does not recognise

Abstract:

Current cardiac monitoring devices are rigid, bulky, and integrate poorly with the human skin, obstructing health monitoring for longer periods. With the miniaturization of electronics, soft and stretchable polymer substrate-based cardiac monitoring device is being developed at Mycronic AB to overcome the aforementioned issues and replacing the traditional rigid electronics-based cardiac monitoring devices. Manufacturing of stretchable cardiac monitoring device includes new materials and manufacturing techniques as well as different end-of-life treatments. The sustainability of this kind of st
