All around the globe the consumption of raw materials by the construction industries is accumulating day by day resulting with an depletion of natural resources, increasing the environmental impacts and CO2 emissions all over the surroundings. Today steel and concrete are widely used and are dominating construction materials in construction industry. These two construction materials are different products and have distinct production flow with significant impact on the environment. The amount of embodied energy and operational energy which is consumed in the process of production, recycling and reuse are becoming increasingly more important in the construction industries due to the potential shortage of natural resources in the near by future and due to the inflation in the energy prices.

This master’s thesis determines some of the problems of antagonistic environmental impacts due to the use of steel and concrete in the construction industries. To mitigate these environmental impacts there are two technology and policy strategies summarized in this thesis. i. ii.

Reduce consumption; and Material selection to reduce impacts. Reduce consumption: All around the globe the consumption of materials is growing day by day with an increase in the population resulting with a depletion of virgin materials. This depletion of virgin materials can be reduced with the help of recycling and reuse of the structural members. Recycling of structural members is already practiced widely than reuse; reuse of the structural members additionally reduces the consumption of virgin materials. High level of reuse of the structural materials can be achieved by establishing design standards and regulations for structural sections, and developing a market for reusable structural sections.



Material selection to reduce impacts: For the selection of construction materials with minimum impact on the environment the designers needs to have apropos education or tools. The main areas for augmentation are identified as education of designers, and standardization and simplification of selection tools like Life Cycle Assessment (LCA). Some of the main


recommendations are: LCA tools standardization; reduce the impact sections and make these impact sections comprehendible and integrate uncertainty data and educating designers about material selection tools with organized programs.


We would like to thank our parents for there unconditional support who put up with long hours and gave us push to complete our thesis.

Furthermore we would like to thank our instructor Dr. Maria Fredriksson who was an inspiration and continual source of knowledge, motivation and good conversation. We thank Mr. Henrik Eriksson for reading our thesis and offering valuable advice. We would also like to thank Mr. Roy Andersson for his valuable time. Thank You.

During our thesis we had much input and feedback from my close friends.

Finally, we would like to thank our colleague at University College of Boras for their views and opinions.
