Abstract: The continued growth of the steel industry poses concerns for the health of the planet and the health of the environment. The waste produced by the steel industry is an untapped resource that is not used nearly as much as it should be. The potential of using basic oxygen steelmaking slag (BOS) as a fertilizer was tested on cereal wheat plants' growth, with samples that are both hydrophobic and hydrophilic through functionalization. Parameters tested included: mass gain, height grown (cm), germination rate (GR), mean germination time (MGT) and a composite visual score (CVS). The results found that the BOS slag improved the growth of the samples due to the high amount of Ca and Fe provided to the sample. It was proposed that the improved performance of hydrophobically functionalized slag over those with hydrophilic functionalization was due to the water reservoir created around the seed. Lanolin functionalized samples are the optimum fertilizer in this study, providing the optimum conditions for nutrient transfer to the seed samples.
