<p>Biomedical waste has become a major point of concern these days due to the adverse impacts they have on the environment. According to the World Health Organization (WHO), while 85% of the waste generated from healthcare activities is general and non-hazardous, the remaining 15% is considered to be biohazards as they can be infectious, poisonous and radioactive. This is why it is important to come up with an effective biomedical waste management system. Biomedical waste poses a potential threat to patients, healthcare workers, public and the environment.</p>.<p class="CrossHead">Infectious diseases</p>.<p>Biomedical wastes, if not disposed appropriately, may result in the contamination of bacteria that can spread to humans, thereby causing an epidemic and infecting a large number of people. In case medical waste is dumped in a landfill without segregation and waste treatment, harmful microbes can seep into the water supply and contaminate water. WHO estimates that about 16 billion injections are administered across the world every year. However, not all needles and syringes are disposed of properly and this amps up the risk of sharp injuries and increases the chance of contracting HIV, Hepatitis B and Hepatitis C virus on reuse.</p>.<p>Open burning of biomedical waste can never be an option to deal with the crisis as incineration of healthcare waste can lead to the release of dioxins, furans and particulate matters. Burning of this waste could also result in the emission of chemical and biological hazards like drug-resistant microorganisms into the environment.</p>.<p>Understanding the importance of effective management of biomedical waste, the Government of India, in a 1998 notification, included hospital waste management as a part of the hospital hygiene and maintenance activities.
