Hyderabad, July 18: Majority of city hospitals are generating biomedical waste exceeding the limits prescribed by the Bureau of Indian Standards. A study by the AP Pollution Control Board found that Nizam Institute of Medical Sciences was generating the biggest amount of biomedical waste followed by Gandhi and Osmania General Hospitals. The improper disposal of the biomedical waste may lead to serious health disorders. However, most hospitals, including mushrooming veterinary clinics, adopt unsafe biomedical waste disposal methods. As per BIS rules, hospitals can generate solid waste amounting to about 1 to 2 kg per bed per day. However, according to the APPCB study covering 10 hospitals, this is not the case in the city. NIMS generates 3 kg solid waste per bed per day, OGH has 2.75 kg per bed and Gandhi Hospital around 2.95 kg per bed per day. In Apollo Hospitals, the waste generated was 2.62 kg per bed while Niloufer Hospital too has crossed the limit. However, hospitals such as Mahavir, CDR, Medwin, and MNJ Cancer Hospital are well within limits. Officials of the department of environment and forest said many hospitals dumped such wastes in their premises and the GHMC cleared them along with the other domestic waste. "Biomedical waste discharged through sewerage will contaminate Musi River and this would pose a serious health risk," said the official. "Non clinical waste accounting for 60% of garbage does not pose any danger to people and environment." The four tonnes of clinical and biomedical waste produced in the city include intravenous bottles, bandages, blood sachets, disposed needles, plastic tubes, aborted foetuses and other human waste. Ideally, the waste must be managed in an environmentally sound manner and even the sanitary workers handling them have to be protected. The wastes from hospitals and nursing homes are also affecting major cities, Vishakapatnam and Vijayawada. "An interesting find of the APPCB is that corporate hospitals generate more quantities of waste when compared to others," said the official. In most government hospitals, the incinerators meant for burning up biomedical waste are not working. APPCB has filed cases against several hospitals but the situation has not improved much.
