Decontamination of Infectious Waste The METEKA Hygiene and Infection Prevention System is the optimal solution for the decontamination of infectious waste. The treatment of the waste takes place “on-site” in a safe, simple and environmentally friendly system. The collection and decontamination of infectious waste in collection and transport containers directly at the point of origin can prevent the spread of infections. It protects both hospital and disposal staff and patients from injury and infection.
