By 2030, renewable Energy Sources (RES), and its infrastructures, are expected to increase 40% in Europe. Parts of RES strategies are onshore and offshore wind energy. The investment into new RES infrastructure implies an update of the current wind turbines, resulting in waste of the composite materials that constitute blades. To turn RES into the most promising and economically viable sources of renewable energy, we need to provide clean renewable energy without any emissions during operation. The blades, among the most important components in the wind turbines, made with composite, are currently regarded as unrecyclable. It is estimated that by 2050 the end-of-life (EOL) blades waste will generate more than 2 Mt annually, and cumulative blade waste in 2050 will lie between 21.4 Mt and 69.4 Mt, worldwide. EOL options for decommissioning wind turbine blades should be explored with the aim of providing environmentally favorable guidelines for managing wind turbine blade waste, and the possibility for material recovery and recycling is crucial if circular economy is the goal in the wind power sector. One possibility to avoid the accumulation of EOL blades in the environment is to convert the composite blades into new environmentally friendly building materials such as green cement. This option would demand some processing of the composite waste. Another option could be the reuse of the blades directly without much processing, e.g. . as new blades or as other products. Furthermore, the composite waste from blades could be combined with similar waste from other industrial sectors to enlarge the potential of a composite wind blade recycling process. Therefore, the general scope of the proposed project is to evaluate and demonstrate in large scale the possibility of recycling or resource recovery from blades and similar waste materials in a large consortium with some of Europe's key players in areas of importance for the project.

Society is dependent upon the continuous functioning of critical infrastructures such as road bridges and energy supply. These infrastructures are exposed to high loads and harsh environmental conditions through their lifetime in operation and materials failures lead to down time having vast negative effects on productivity and well-being in society in terms of lost time, shortened life cycles and increased service costs. So engineers face the challenge to develop durable materials compatible with industrial standards in an economically viable way. Composites represent attractive materials and are increasingly used for such applications since they demonstrate low weight, high strength and stiffness and high environmental resistance. However composites suffer from sudden brittle failure mainly due to production defects and handling damages; this is currently handled by strict quality and process control from manufacturers, resulting in high production costs which can represent a barrier to introduction and development of composites in a wide range of applications. The general objective of DACOMAT is to develop more damage tolerant and damage predictable low cost composite materials in particular aimed for used in large load carrying constructions like bridges, buildings, wind-turbine blades and off shore structures. The developed materials and condition monitoring solutions will enable composite structures to be designed and manufactured as large parts allowing for more and larger manufacturing defects and the need for manual inspection to be dramatically reduced. A demonstration of the materials’ performances in relevant environment will be conducted in two business cases: wind turbine blades and road bridge beams, while both LCC and LCA analysis will also strengthen the project’s credibility.The project gathers the full industrial value chain: ranging from materials development and manufacturing to composite parts demonstrators and standardisation.
