What is Biomedical Waste?

Biomedical waste, also known as hospital waste or healthcare waste, refers to any waste produced during the diagnosis, treatment, or immunization of humans or animals. It also encompasses waste produced during research activities and the production or testing of biological products. It includes a broad range of materials, from used syringes and bandages to chemical waste and expired medications. Discarded sharps like used needles are also considered as biomedical waste. Biomedical waste is a type of biowaste which are generally of organic origin and biodegradable in nature. Proper management of this waste is vital to prevent contamination and harm to healthcare workers, patients, and the general public.

Types of Biomedical Waste

Understanding the different types of biomedical waste is crucial for effective management. The main categories include:

Infectious Waste: Waste contaminated with blood, body fluids, or other infectious materials, such as used gloves, gauze, and surgical instruments.
Pathological Waste: Human or animal tissues, organs, body parts, and fluids removed during surgery or autopsy.
Sharps Waste: Items that can cause punctures or cuts, such as needles, scalpels, and broken glass.
Chemical Waste: Discarded chemicals used in laboratories, cleaning agents, and disinfectants.
Pharmaceutical Waste: Expired, unused, or contaminated medications and vaccines.
Genotoxic Waste: Waste containing substances with genotoxic properties, such as certain chemotherapy drugs.
Radioactive Waste: Waste containing radioactive substances used in medical treatments and diagnostics.
Non-Hazardous Waste: General waste that poses no risk, such as paper, cardboard, and kitchen waste from healthcare facilities.

According to World Health Organization, 75-90% of the waste from healthcare providers is similar to household waste and can be labelled as “non-hazardous” or “general healthcare waste.” This waste mostly comes from administrative tasks, kitchens, housekeeping, packaging, and building maintenance at healthcare facilities. The other 10–25% of healthcare waste is considered “hazardous” and can cause various health and environmental risks.

Importance of Biomedical Waste Management

Biomedical waste management is crucial for protecting public health and the environment. Proper handling, treatment, and disposal of biomedical waste prevent the spread of infections and diseases, safeguarding healthcare workers, patients, and the community. It also reduces environmental pollution by preventing harmful chemicals and pathogens from contaminating air, soil, and water. Additionally, adhering to regulatory standards helps healthcare facilities avoid legal penalties and maintain their reputation. Effective biomedical waste management conserves resources through recycling and promotes sustainability, contributing to a healthier ecosystem and a safer world.

According to a recent World Health Organization (WHO) report, improper handling of biomedical waste (BMW) remains a global issue, especially amid the COVID-19 pandemic. The rapid growth of healthcare services has led to a significant increase in BMW generation. Proper segregation, collection, treatment, and disposal of biological waste are crucial to prevent the spread of infectious diseases and protect healthcare workers, waste handlers, and the public. The report indicates that over 16 million injections are administered annually worldwide, generating more than 85 million tons of BMW. With current global health challenges, proper BMW management is essential.

Biomedical Waste Management Strategies

Biomedical or healthcare waste management strategies include proper segregation, collection, transportation, treatment, and disposal. Regular staff training, use of personal protective equipment (PPE), and adherence to regulations enhance the effectiveness of these strategies.

Waste Segregation

Segregation is the first and most crucial step in biomedical waste management. Proper segregation ensures that different types of waste are handled and treated appropriately. Effective segregation reduces the risk of contamination and makes the disposal process more efficient. Waste should be segregated into the following categories:

Yellow Bags: For infectious waste, pathological waste, and chemical waste.
Red Bags: For contaminated waste that can be disinfected and recycled.
Blue/White Bags: For sharps and other items that require special handling.
Black Bags: For general waste that is non-hazardous.

Collection and Transportation

Biomedical waste must be collected and transported safely to treatment and disposal facilities. Secure, leak-proof containers should be used to prevent spills and contamination. Transportation vehicles must be equipped with safety features and clearly labelled with biohazard symbols. Waste should not be stored for more than 48 hours to prevent the growth of pathogens.

Treatment and Disposal Methods

Biomedical waste must be treated to neutralize pathogens and reduce its hazardous nature before disposal. Common treatment methods include:

Autoclaving: Using steam under pressure to sterilize infectious waste.
Incineration: Burning waste at high temperatures to destroy pathogens and reduce waste volume.
Microwave Treatment: Using microwave radiation to disinfect waste.
Chemical Treatment: Applying chemicals to disinfect and neutralize waste.
Thermal Treatment: Using heat to treat waste without combustion.

After treatment, biomedical or healthcare waste should be disposed of in a manner that minimizes environmental impact. Treated waste can be disposed of in sanitary landfills or through other environmentally friendly methods. Sharps waste should be encapsulated in concrete or other materials to prevent injury. By following the strategies outlined in this guide, we can make significant strides toward a more sustainable and waste-free world.
