Purpose and goal
The project aims to prepare for scaling up Anferras´ patent-pending hydrometallurgical recycling process, converting steel industry waste, specifically grinding sludge, into iron chloride for water treatment, and hydrogen gas. Through collaboration with stakeholders across the value chain, the study will evaluate technical, economic, and environmental aspects, with the goal of providing a basis to optimize these elements and achieve effective, sustainable large-scale implementation.
Expected effects and result
The project is expected to deliver a scalable, economically sustainable recycling process for grinding sludge with significant environmental benefits, producing high-quality iron chloride for water treatment. The long-term effect goal is large-scale implementation of Anferras´ technology, eliminating the need to landfill or incinerate steel grinding sludge.
Planned approach and implementation
The feasibility study comprises seven integrated work packages, covering experimental process development and verification, an LCA study in accordance with ISO 14040 and 14044, as well as market and risk analyses. Finally, a detailed plan is developed for a pilot project to reach TRL level 5 and a strategy for large-scale implementation.
