Empty toner cartridges should not be put in the regular trash bin. Instead, they should be recycled properly to reduce waste and environmental impact.  Recycling toner cartridges allows the materials like plastic and metals to be reused for creating new products. Disposing of cartridges in the trash can lead to them ending up in landfills, contributing to pollution.  To responsibly dispose of empty toner cartridges, consider using in-store recycling programs, mail-in recycling programs, manufacturer's recycling initiatives, local recycling centers, or third-party recycling services.
