By increasing the use of recycled scrap materials, MOWSES aims to significantly reduce carbon emissions while maintaining the strength, durability, and reliability required for applications such as energy and construction. A crucial step in achieving these goals is the development of a comprehensive test matrix, a structured framework that defines how green structural steels are evaluated across different conditions and use cases. This matrix serves as the backbone of the MOWSES project, ensuring that experimental work, simulations, and material characterisation are aligned and comparable across all project partners. Given the variability introduced by recycled materials, green steels can contain higher levels of residual elements such as copper or nickel, which influence weldability and mechanical performance. The test matrix is therefore designed to systematically assess how these variations affect key properties, particularly in critical areas like welded joints and heat-affected zones.
Linking experiments, modelling, and real-world applications
The defined testing framework enables researchers to connect laboratory experiments with advanced modelling approaches, including machine learning, thermodynamic simulations, and finite element analysis. These methods allow for precise predictions of how different material compositions and welding conditions impact performance. By integrating these approaches, MOWSES ensures that results are not only scientifically robust but also relevant for real-world applications. The test matrix supports the identification of safe operating conditions and helps establish guidelines for the use of green steel in infrastructure projects, from wind turbines to large-scale construction.
Advancing safe and sustainable steel innovation
Developing such a structured evaluation framework is essential for accelerating the adoption of green steel technologies. It provides a common basis for comparing results, validating new materials, and ensuring compliance with safety and performance standards. Ultimately, the work carried out within MOWSES contributes to Europe’s broader goal of achieving climate-neutral infrastructure. By defining how green steels should be tested and validated, the project lays the groundwork for their reliable use in future energy systems and construction projects—combining sustainability with structural integrity.
