Why Call It Medical Waste?

Medical waste is commonly used in healthcare to refer to any waste generated from medical activities.

 However, this type of waste can be known by various names, each reflecting different aspects of its origins and management.

The primary term is “regulated medical waste,” but it can also be referred to as “biohazard waste,” “biomedical waste,” or simply “biohazardous waste.”

In some contexts, you might encounter terms like “red bag waste,” which indicates the specific type of bags used for disposal, or “sharps waste,” which pertains to items that can puncture or cut, such as needles and blades.

It is essential to distinguish between medical and hazardous waste, as they are not the same and should not be mixed.

In summary, while “medical waste” is the overarching term, it encompasses several other names, each with significance within the healthcare waste management framework.

Now That You Know Why We Call It Medical Waste, Let’s Discuss Who Regulates It

Medical Waste Tracking Act of 1988

After discovering medical waste on several East Coast beaches, concerns about potential health risks led Congress to enact the Medical Waste Tracking Act (MWTA) in 1988. This legislation, which amended the Solid Waste Disposal Act, introduced several key provisions:

1. Definition of Medical Waste: The act defined medical waste and outlined which types would fall under its regulatory framework.

2. Tracking System: It established a cradle-to-grave tracking system that requires medical waste generators to initiate tracking through a designated form.

3. Management Standards: The MWTA established management standards for medical waste, including segregation, packaging, labeling, marking, and storage.

4. Record Keeping and Penalties: It imposed record-keeping requirements and specified penalties for mismanagement of medical waste.

The Environmental Protection Agency (EPA) implemented the MWTA regulations on March 24, 1989.

These regulations governed a two-year program that commenced on June 24, 1989, and concluded on June 21, 1991, operating in New York, New Jersey, Connecticut, Rhode Island, and Puerto Rico. During this timeframe, the EPA gathered valuable information and conducted multiple studies related to medical waste management. The MWTA and the EPA’s program raised awareness about medical waste issues.

They served as a framework for states and other federal agencies to develop medical waste management programs.

Moreover, the MWTA mandated that the EPA evaluate various treatment technologies available to determine their efficacy in reducing the disease-causing potential of medical waste. In 1990, the technologies assessed included:

• Incinerators and autoclaves (both on-site and off-site)

• Microwave units

• Various chemical and mechanical systems

The data collected under the MWTA and concurrent EPA investigations concluded that the risk of disease caused by exposure to medical waste is highest at the point of generation and diminishes thereafter.

Consequently, the risk posed to the general public is significantly lower than that faced by individuals occupationally exposed to medical waste.

What Is The Medical Waste Cycle

Effective medical waste management encompasses a comprehensive process beyond the point where waste is removed from a facility.

Gaining insight into each stage of the waste cycle, including the procedures after materials leave your premises, is essential for ensuring that your waste management practices are compliant and environmentally sustainable. Below is a concise explanation of each medical waste management continuum stage.

1. Generating Waste: In the dynamic healthcare delivery environment, healthcare workers can generate a wide array of medical waste during patient care.

• Regulated Medical Waste (RMW): This category comprises waste that poses a potential risk of infection and is subject to stringent regulations governing its collection, transportation, treatment, and disposal. Items classified as biohazardous waste, particularly those saturated with blood or other potentially infectious materials, are essential within this realm. This includes soiled gauzes, patient drapes, and specific types of personal protective equipment that can harbor pathogens.
• Sharps: A critical subset of RMW, sharps are defined as any object capable of puncturing the skin. This includes an extensive range of potentially dangerous items such as needles, scalpels, syringes, and even fragmented glass, all of which can pose significant health risks if not managed properly.
• Unused or Expired Pharmaceuticals: This waste stream encompasses a variety of medications that may be deemed non-hazardous, alongside more dangerous substances like warfarin. The improper disposal of these pharmaceuticals can lead to environmental contamination and public health concerns.
• Hazardous Chemicals: This category includes a variety of toxic substances, such as cleaning fluids and other dangerous chemicals that can pose severe health risks to humans and the environment if mishandled.
• Chemotherapeutic Waste: Any waste generated from the administration of chemotherapy falls within this category. This hazardous waste requires specialized handling due to its potential to cause harm to healthcare workers and the public.
• Controlled Substances: These include any drugs regulated by the Drug Enforcement Administration (DEA), such as opioids. Due to their potential for abuse and addiction, these substances require meticulous care in both usage and disposal.

Various regulatory bodies oversee the management and disposal of medical waste, each tasked with ensuring safety and compliance. For instance, the Occupational Safety and Health Administration (OSHA) oversees the safe handling of waste containing bloodborne pathogens, encompassing sharps and other regulated medical waste.

Meanwhile, individual state agencies establish regulations to dispose of RMW, accounting for state-specific public health needs.

The Environmental Protection Agency (EPA) regulates the disposal of hazardous waste pharmaceuticals, ensuring that these substances do not pollute air and water resources.

Additionally, the Drug Enforcement Administration (DEA) oversees the handling and disposal of controlled substances, providing strict guidelines to mitigate the risks associated with these powerful drugs. Once medical waste is removed from the healthcare facility, the Department of Transportation (DOT) governs its transportation, enforcing regulations that ensure hazardous materials are transported safely and responsibly.

2. Segmenting Waste: It is essential for healthcare professionals to meticulously segment waste to ensure the safety of healthcare workers, minimize the spread of harmful pathogens, and facilitate appropriate treatment after waste exits the facility. This involves disposing of waste in clearly marked containers specifically engineered to hold each type of waste securely.

   For example, most regulated medical waste (RMW), except sharps and chemotherapeutic waste, can be efficiently disposed of in hygienic red bags designed to fit seamlessly within designated waste containers.

Regarding sharps disposal, healthcare staff must utilize FDA-cleared, puncture-proof containers that safeguard against potential injuries.

These containers can be reused, significantly reducing plastic waste that ultimately ends up in landfills.

Moreover, the healthcare system offers specially designed containers tailored for various types of waste, including controlled substances, pharmaceuticals, hazardous chemical waste, and trace amounts of chemotherapeutic waste, ensuring that each category is handled with the utmost care and in compliance with regulations.

3. Preparing Waste Containers for Transport: When a waste receptacle reaches capacity, designated staff must meticulously prepare it for transport to the waste management facility.

   This preparation process involves securely sealing the container’s contents to prevent potential leakage that could compromise safety.

For red bags containing non-sharp Regulated Medical Waste (RMW), the closed bag should be carefully placed within a sturdy transport container.

Once the outer container is securely closed and sealed, no part of the bags must be visible, ensuring compliance with safety standards and promoting prudent waste management practices.

Suppose the waste is scheduled to be picked up by a licensed waste hauler.

In that case, it is vital to adhere to Department of Transportation (DOT) guidelines regarding proper marking, the weight of the box, manifest or shipping paper details, and any other applicable regulations. In cases where the waste is being mailed to a waste management facility, strict compliance with postal requirements is necessary.

Please use appropriate labels that meet the standards the United States Postal Service (USPS) set forth to ensure safe and legal waste transport.

4. Stage Four: Treating Waste: Upon arrival at the waste management facility, a dedicated medical waste management partner carefully orchestrates the handling of medical waste, ensuring adherence to the facility’s specific permit requirements, as the relevant state regulatory agency dictates.

The predominant method for treating medical waste is autoclaves, sophisticated machines designed to transform hazardous materials into non-infectious waste. Initially, trained staff meticulously weigh the incoming waste before placing it into designated bins, which are then transported to the autoclave.

Within this controlled environment, air is effectively evacuated and replaced with high-pressure, high-temperature steam, maintained for a critical period of 20 to 30 minutes. This intense process is highly effective in eradicating any harmful pathogens that may be present within the waste. Once the cycle is complete, the “cleaned” waste is compacted, making it ready for safe transport.

Incineration is the required treatment method in certain instances, particularly for materials such as sharps contaminated with pathological or trace chemotherapeutic waste.

This process applies extreme heat to the waste, facilitating thorough combustion that eliminates any hazardous elements, reducing them to ash. This method is crucial, destroying the waste and minimizing the risk of harmful chemicals seeping into local waterways.

Your medical waste management partner will provide detailed shipping information to maintain transparency and regulatory compliance. This documentation serves as evidence of compliance and can be pivotal should any regulatory authority require verification of the waste treatment process.

5. Sending Treated Waste to Its Final Destination: Once medical waste has been treated to be rendered non-infectious or destroyed, it embarks on its journey to a final disposal site.

   Depending on local regulations and practices, this site may be a landfill or a waste-to-energy (WTE) facility. The transformation of waste directed to a WTE site is remarkable: converted into valuable, clean electricity.

This sophisticated WTE process employs specially designed boilers that ignite non-hazardous waste within a closed-loop system, ensuring minimal environmental impact.

As the materials combust, they release an immense amount of heat, which is captured and repurposed to produce steam. This steam then drives a turbine, generating electricity dispatched to local utility companies and ready to power homes and businesses.

Alternatively, this generated electricity can be returned to the waste management facility, providing energy to operate equipment and help sustain the waste processing operations, creating a circular and efficient system.
