This thesis showcases applications for structural reusing wind turbine blades. Wind turbine blades are extremely difficult to recycle and thus reuse avenues are being researched to extent the useful lifetime of these blades. The goal of this thesis is to generate applications that utilise segments cut from wind turbine blades. This goal is approached in four steps: end of life, wind turbine blade design, cutting strategies and applications.
The first part focuses on the end of life of wind turbine blades. Analysing current and future waste management solutions that have been explained trough the lens of a waste hierarchy. Showing why reuse is a better option than current solutions and how this thesis fits into the entire reuse landscape.
The second part analyses wind turbine blades to better understand the design philosophies behind them and how this influences the reuse of wind turbine blades. It was found that the design, materials and the state of blade all influence reuse strategies.
The information found these first two parts is then used to generate the possible cutting strategy, cutting pattern and applications in the final two parts off this thesis.
The third part ideated on a possible cutting strategy showcasing what steps should be taken to reuse wind turbine blades. Looking into the logistical and processing difficulties.
The last part uses all the information found and combines the knowledge to create a cutting pattern and a proposal for an applications. A cutting pattern using rectangular or triangular segments and simple beams was created that is used to create a concept of an adventure park.

The global production of steel in a year is in the range of several millions of tonnes due to its essential function in industries such as automotive, manufacturing, and construction among others. However, a major challenge faced by the steel industry in the development of new steel grades is the inability to predict surface behaviour, such as the concentration profiles of alloying elements like manganese. This is due to the inability to predict the oxidation behaviour during the processing of steel. In order to solve this challenge, experimental data regarding oxidation on a short timescale is required which is not yet well-addressed in literature. Some of this data required will be generated in this research project via the experimental investigation of the oxidation of Fe-Mn binary alloys at high temperature. In this project, the oxidation experiments are performed on Fe-Mn alloys having a manganese composition ranging from 0.5-7% Mn in temperatures ranging from 1000-1150 degrees Celsius and oxygen partial pressures ranging from 0.1-0.3 atm. The oxidation behaviour is studied using thermogravimetric analysis and the oxide layer is then characterised using X-ray diffraction. The in-situ evolution of oxide structure is observed using high temperature X-ray diffraction, and finally the rate determining mechanism for the oxidation of Fe-Mn alloys at high temperature is identified.
