The product

Granella® is an example of circular economy, whereby scrap is turned into a product.

The steel obtained from ferrous scrap melting in the electric furnace also generates a by-product – the so-called “slag” – whose chemical properties are similar to those of effusive rocks.

The materials obtained from this process have enhanced physical and mechanical characteristics compared to high grade aggregates from effusive origin such as basalt, diabase and porphyry, which are usually used to prepare high performance special bituminous concrete (highly adhering, sound-absorbing and drainage road surfacing).
The better combination of micro- and macro-roughness increases adherence values in road pavements, thus improving safety.

Furthermore, Granella® offers a two-fold advantage in terms of environmental protection: from the one side, it results from recycling and valorising an industrial by-product that otherwise would be considered as waste; on the other side, it is a valuable replacement to natural raw materials that, in this way, are no longer overexploited. This product is oriented toward an increasingly sustainable use of resources.
