In this study, the potential for transforming valuable metals in industrial waste sludge into a useful product and thus reducing the amount of waste was investigated. So, waste sludge from the metal coating industry with high Fe and Zn content and waste glass were vitrified by adding 1-5-10-15-20-25% by weight of sludge to glass. The structural, optical and antimicrobial (antibacterial and antifungal) analyses were carried out. XRD results of the products showed that there are no peaks associated with any crystalline phase, as expected for an amorphous structure. According to XRF analysis, the products can be classified as soda-lime-silicate glass. FT-IR results revealed the presence of intense silicate and iron oxide peaks in vitrified products. TCLP analysis proved that all heavy metals leached from sludge were successfully stabilized in vitrified products. According to the optical transmittance, vitrified products including 20–25% waste sludge have potential use as the bandpass optical filter. These vitrified products showed 93–94% antibacterial activity against E. coli and 93 − 91% antibacterial activity to S. aureus, respectively. Additionally, these vitrified products have broad spectrum antimicrobial effect (91%).
