Abstract
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...
