Medical waste involves a wide range of disposed materials generated from healthcare facilities, research laboratories, veterinary clinics, and even households. Its proper disposal and management is a critical aspect frequently overlooked and comes with severe consequences that compromise public health, the environment, and the overall well-being of communities. This article aims to shed light on the hidden dangers associated with medical waste and provide guidelines for its safe and responsible management.

Understanding Medical Waste

Generally, medical waste refers to anything used and discarded during the diagnosis, treatment, or immunization of humans or animals, as well as research activities involving biological substances, including:

• Sharps - needles, lancets, insulin injections, razor blades, scalpels, metal wire, scissors, or other sharp objects that may pierce the skin
• Used hair caps, surgical gloves surgical masks, and lab gowns
• Used and contaminated first aid or surgical bandages and dressings
• Pathological waste, pharmaceuticals, and chemical substances

During the challenging times of the global COVID-19 pandemic, the significant concern about medical waste has become more pressing and has reached common people's homes through the rampant use of disposable face masks and at-home self-testing kits. 

Disposable face masks have been widely used as a preventive measure to reduce the transmission of the coronavirus. These masks are typically made of materials such as polypropylene, which is not biodegradable and can pose a threat to the environment if not disposed of correctly. Similarly, antigen tests, commonly used for rapid COVID-19 testing, generate medical waste in the form of used test kits and associated protective gear.

Why Proper Medical Waste Disposal Should Be A Priority

• Cut Risks of Transmission of Bloodborne Pathogens

Correct medical waste disposal reduces sharps injuries, which pose a high risk of transmitting bloodborne pathogens, such as hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). If a healthcare worker or individual comes into contact with a contaminated sharp, there is a chance of contracting these infections. It is estimated that sharps injuries are responsible for a significant number of healthcare-associated infections worldwide. 

• Prevention of Environmental Contamination

Medical waste contains hazardous materials that can contaminate the environment if not disposed of properly. Pharmaceuticals, chemicals, and biohazardous substances can leach into soil and water sources, affecting ecosystems and potentially entering the food chain. By ensuring proper disposal, we reduce the risk of environmental contamination and its associated consequences.

• Safety of Healthcare Workers and Waste Handlers

Healthcare workers, waste handlers, and individuals involved in the collection, transport, and disposal of medical waste are at higher risk of sharps injuries and exposure to infectious diseases. These can have serious consequences, including physical harm, emotional stress, and potential long-term health issues. Occupational safety should be a priority to protect workers from such injuries and associated infections. 

• Impact on Healthcare Delivery

Injured or sick healthcare workers may require medical attention, resulting in increased healthcare costs and potential work absences. These injuries can also affect staff morale, productivity, and the overall quality of patient care.

• Minimization of Cross-Contamination

Adhering to standardized medical waste disposal helps prevent cross-contamination between different waste streams. By segregating and disposing of medical waste separately, we reduce the risk of contaminating regular waste and recycling streams. This segregation ensures that waste is managed appropriately, protecting the health of waste handlers and promoting effective recycling practices.

• Ethical and Social Responsibility

Last but not the least, prioritizing proper medical waste disposal reflects our ethical and social responsibility towards the environment, public health, and future generations. By managing medical waste responsibly, we contribute to a safer and healthier society, demonstrating our commitment to sustainable practices and community well-being.

Safe Management Practices You Can Do At Home

Since the advocacy of proper medical waste disposal is a mammoth of an issue, it’s easy for anyone to assume that you’re helpless about it and there’s nothing you can do to change the situation unless you’re not working in the government or the medical field. But believe it or not, small everyday habits can go a long way. Here are some important considerations to effectively manage medical waste at home and reduce its impact.

• Whenever possible, opt for reusable cloth masks rather than disposable ones. Unlike disposable masks, which are single-use and contribute to waste accumulation, cloth masks can be reused multiple times. By using cloth masks, you reduce the amount of mask-related waste generated and minimize our environmental footprint. It’s also a viable alternative if you’re after cost-effectiveness and customizations geared toward comfort and sophisticated filtration options.

While cloth masks have these advantages, it's important to note that they require proper care and maintenance. Regular washing and drying at high temperatures are necessary to maintain hygiene and effectiveness. Additionally, cloth masks should fit snugly, cover the nose and mouth fully, and be worn consistently with appropriate hand hygiene practices to provide optimal protection.

• Put a premium on the benefits of a clean home, most especially when someone in your household is sick. Clean and disinfect high-touch surfaces. Designate a specific container or bag for medical waste within your home. This could be a small trash bin or a sealable bag. Ensure that it is clearly labeled to avoid confusion with regular household waste. Disposable face masks and antigen tests should be placed in this container separately from other trash.

• When removing a used face mask or disposing of an antigen test, take precautions to minimize contact with potentially contaminated surfaces. Avoid touching the front of the face mask, as it may have come into contact with respiratory droplets. Remove the mask by using ear loops or ties, fold it inward to trap any pathogens, and place it in the designated medical waste container. Similarly, carefully place used antigen tests and their associated materials in sealed bags before disposal.

• Ensure that the container or bag holding medical waste is securely sealed or tied to prevent any accidental spills or contamination. Place it in a designated area away from children, pets, or vulnerable individuals until it can be properly disposed of.

• Follow the recommended methods of disposal based on the guidelines provided by your local authorities. They may include options such as arranging for pickup by a medical waste management service or dropping off the waste at designated collection points. Avoid disposing of medical waste in regular household trash bins, as this can potentially expose waste collectors and contribute to environmental pollution.

Final Thoughts

Recognizing and raising awareness on this crucial issue is one step closer to achieving adequate safety measures to protect everyone in the community from the dangers of medical waste. However, it requires the joint effort of everyone in the healthcare field and the federal government and the proactiveness of private individuals. You, too, can do your part in minimizing the risks linked to medical waste at home. The simple act of opting for reusable face masks instead of disposable face masks, which can take 450 years to decompose, can already make an incredible difference.
