Steel mill by-product material briquettes or pellets and processes for making the same that results in a briquetted or cold agglomeration pelleted material made from by-product material and a binder comprising gypsum-free cement and sucrose residue for the briquettes or a binder comprising gypsum-free cement and, if required, a sucrose residue for the pellets. These briquettes or pellets are made using a cold roll briquetting process or a cold agglomeration pelletizing process at ambient temperature and can be fed directly into a blast furnace thereby recycling by-product materials while completely by-passing the environmentally adverse and costly sintering process or landfill disposal process.
