Heracless
Heracless is the name of Tata Steel’s large-scale transition project in IJmuiden. The plan replaces the traditional blast furnaces and coke plants with direct reduced iron (DRI) and electric steel production — an intervention that fundamentally redesigns the production process.
From blast furnace to electric.
According to the environmental impact assessment, this transition will lead to a significant reduction in CO₂ emissions. In climate terms, it represents a clear break with the past. In material terms, less changes than the terminology suggests: the system is reconfigured, not resolved.
Where the blast furnace route produced large quantities of blast furnace slag, this residual stream will decrease significantly. At the same time, a new slag stream emerges: EAF slag, while other slag streams decline. Slag does not disappear from the system; it shifts within the process and changes in composition, but retains its ecological significance.
The electric route produces less smoke and soot, but shifts residual materials to other parts of the process. New residual streams emerge, such as EAF dust: a fine, zinc-containing filter dust that, in its current form, is not reused and must be disposed of externally. At the same time, emissions of particulate matter, ultrafine particles and metal-containing fractions persist, while knowledge about deposition and long-term effects remains incomplete.
Heracless does not mark an endpoint, but a reconfiguration within the same system. Emissions decrease in some areas, while new residual streams and uncertainties emerge elsewhere. What is presented as progress is, in essence, a shift of burdens — technically more complex, more diffuse and less visible.
The traces do not disappear.
They shift.
