The in-plant recycling routes of several side streams produced in Electric Arc Furnace (EAF) steelmaking remain under-explored. Briquetting is an attractive technique to enable recycling of inplant side streams. Briquettes introduced into EAF must possess certain mechanical and chemical properties. However, no standard is available to determine the suitability of briquettes used in the EAF process. In this work, eight side streams were characterized, and used to produce seven different briquettes to be used in EAF. Side streams were obtained from three different EAF steel plants as well as two other industrial sites. Briquettes tested consisted of four self-reducing briquettes and three slag-forming briquettes produced using different recipes. The briquettes were subjected to several mechanical and thermal tests which reflect their intended use in EAF. The mechanical tests included compression and drop tests, and the thermal tests included optical dilatometry, TGA-DTG-MS, and full-scale briquette reduction tests. Moreover, melting trials were performed to assess the melting behavior of selected briquettes and their interaction with slag. Suitability of briquettes characteristics were assessed based on values from literature and against reference ferroalloys and lime stones used in one of the steel plants. Two briquettes were deemed suitable for EAF use, while three briquettes were deemed unsuitable, and two briquettes were considered of limited use.

The in‐plant recycling routes of side streams produced in electric arc furnace (EAF) steelmaking remain underexplored. Briquetting is an attractive technique to enable their recycle.

The briquettes are subjected to several mechanical and thermal tests which reflect their intended use in EAF. The mechanical tests include compression and drop tests, and the thermal tests include optical dilatometry, thermogravimetric analysis (TGA)–derivative thermogravimetry (DTG)–mass spectrometry (MS), and full‐scale briquette reduction tests.
