Biological waste

The correct disposal of contaminated waste is a key task in order to minimize or prevent the escape of organisms from a laboratory and thus to avoid any danger to human health and the environment.
Biohazard waste:  ALL materials  used  for cell and/or  bacteria cultures (contact with cells) AND recombinant nucleic acids in all forms, natural and synthetic (e.g., DNA, RNA, shRNA, etc.) are treated as biohazard/infectious waste.
