Vindkraftverkens nedmonteringsprocess i Sverige

Sammanfattning:

The first commercially produced wind turbines in Sweden are starting to reach the

end of their lifetime after approximately 25 years of producing energy. The cost for

dismantling the turbines, according to Ardefors et al. (2009), is calculated to be 1-2 %

of the total investment of the wind turbines. The purpose of this master thesis is to

map the dismantling process of wind turbines in Sweden and try to find a sustainable

solution for the future.

To make sure that a correct dismantling process takes place, and that the financial

aspect is covered, a proposal for a financial guarantee is worked upon. A national

unanimity will be created through a financial guarantee and the risk will be minimal

of a third party getting afflicted.

Studies of literature and interviews have been carried out. To explore the possibilities

to new methods of dismantling the turbines, brainstorming has been done.

The dismantling process of today is uncomplicated and can easiest be described as an

inverted buildup. A second-hand market for wind turbines exists and the need for

recycle has not been that big jet. The problems within the dismantling process are

known but only to a few parties in the business.

Research is carried out within the field of wind turbines today. The efficiency of using

the winds energy or to make the construction easier and better for maintenance are

two important and prioritised areas.

To make a survey in countries that are a step ahead of Sweden, such as Germany,

Denmark or U.S.A., would be very interesting and surely information can be used to

implement it in the Swedish system, but this aspect is not covered in this thesis.
