The Zero Waste project: circular economy applied to steel production

Environmental sustainability concerning Pittini Group’s plants and production processes is considered by the company of the utmost importance.
The Zero Waste project, launched in 1997, is a result of the sustainability principles by which the Environmental Department has always been led. The aim of the project is to enhance the already inherent sustainability of the EAF’s steel production cycle. As a matter of fact, raw materials coming from steel recycling can be endlessly recycled thanks to the above-mentioned method, without steel losing its features. The “Zero Waste” project is addressed to the “ancillary” materials produced by the EAF’s steel production cycle. At present, EAF’s slag, ladle slag and refractory materials are all disposed of. This project entails all the activities aiming to reduce dumping by recycling the aforementioned materials or by transforming them into new products.

Among other initiatives, Ferriere Nord has patented and installed a new rotating reactor system which allows to treat ladle slag – usually considered as a waste product resulting from steel production – in a confined space from which air is being drawn. Thanks to this system, powder can be separated from ferrous scrap and therefore can be reused into the electric air furnace (EAF) as a partial substitute for lime (raw material).

 

The following video is the first of a series dedicated to the Zero Waste project, explaining how Pittini Group is applying Circular Economy principles to steel production.

To Pittini Group Zero Waste means:

  • Recycling, raw material is obtained from steel scrap coming from collection sites
  • Reusing production waste within the production cycle
  • Reducing waste in raw materials by using production waste instead
