HISARNA - DEVELOPING A SUSTAINABLE STEEL PRODUCTION PROCESS ABSTRACT The steel industry in Europe was looking for a way to increase the efficiency of steel production, and redesign the production process in order reduce emissions in order to meet the European Union's targets of cutting the emissions by 80-95% of the 1990 levels by 2050. The steel industry formed a consortium along with universities and research organizations to identify technologies to help reduce carbon emissions, ensure energy efficiency, and achieve flexibility in the selection of raw materials in the steel industry. The consortium chose the European unit of India-based steel maker Tata Steel to execute a project to develop new steel making technology. The result was a new steel making technology HIsarna. This was developed and tested in Tata Steel's IJmuiden plant in the Netherlands. The case describes the way in which the project was developed, executed, by bringing in different technologies, knowledge, and skills from various stakeholders. HISARNA - DEVELOPING A SUSTAINABLE STEEL PRODUCTION PROCESS CASE "Sustainability and a circular economy are very important for our future in Europe, HIsarna offers benefits in both domains."1 Koen Meijer, ULCOS/HIsarna Project Coordinator, R&D Ironmaking, Tata Steel Steel, the most recycled industrial material in the world, was produced through highly energy intensive methods. Though the energy used to produce steel has been reducing since the 1960s, it consumed 6%
