“…As car-bon black derives from hard coal tar, replacing it with a waste material results in the double environmental benefit: reduce slag landfilling and carbon black production. Carbon black replacement has been studied in other studies [34][35][36][37], however this is the first time it is replaced by a waste derived by the steel industry. Regarding epoxy matrix for some applications, it is filled with quartz or silica [38,39].…”

Innovative Reuse of Electric Arc Furnace Slag as Filler for Different Polymer Matrixes

The European steel industry produces about 70 million tons/year of steel by the electric arc furnace (EAF). The slag consists of about 15% by weight of the produced steel, thus from the perspective of the circular economy, it has a high potential as a co-product. This research aims to assess an innovative reuse of EAF slag as filler in different polymer matrixes: thermoplastic (polypropylene), thermosetting (epoxy resin), elastomeric (nitrile butadiene rubber), and recycled end of life rubber tire. A comparison between neat polymer and polymer filled with a certain amount of EAF slag has been carried out by tensile (or flexural), compression, and hardness tests. Experimental results show that slag as a filler increases the composites’ hardness and elastic modulus at the expense of toughness. For a safe reuse of the slag, the leaching of hazardous elements must comply with current legislation. It was found that, although the used EAF slag releases small amounts of Cr, Mo, and V, incorporating it into a polymer matrix reduces the leaching. The EAF slag particles distribution has been observed by scanning electron microscopy (SEM) images. The obtained results show good technical feasibility of this innovative slag application so that it could pave the way to a new industrial symbiosis between dissimilar sectors, bringing economic and environmental benefits.

This work shows an innovative application for electric arc furnace (EAF) slag: its use as a filler for nitrile butadiene rubber (NBR). Composites with various EAF slag contents were tested. It was found that the polymer matrix significantly reduces the leaching of slag (determined according to the standard CEN-EN 12457-2) incorporated in the NBR. The processability characteristics determined by the rheometric curves highlight that the EAF slag accelerates the crosslinking kinetics, reducing the production cycle time. Mechanical characterization demonstrated that EAF slag increases hardness and compression modulus. The ability to recover an imposed deformation quantified by the compression set is reduced as the EAF slag amount increases but remains below an acceptable value. It can be stated that in sealing systems, the EAF slag as a filler for NBR positively affects the compound properties. Moreover, NBR filled with EAF slag also has magnetic properties compared with standard rubber.
