Little or no carbon addition needed which means savings in terms of the material costs associated with coke. 

Emissions are greatly reduced compared with traditional processes, particularly if the electric supply is largely from renewable sources. This reduction in emissions not only aligns with environmental sustainability goals but also underscores the positive impact of the Mineral wool production process on mitigating climate change. By relying on renewable energy sources for electricity, the production process minimizes its carbon footprint, contributing to overall environmental preservation efforts.
