What is Medical Waste? Medical Waste Definition, Types, Examples, and More

Medical waste disposal is one of the biggest day-to-day challenges faced by healthcare providers. It’s often complicated by other concerns like HIPAA, epidemiology, potential civil litigation, and state and local regulation. Because at MedPro Waste Disposal we aim to help providers become better providers, we’re taking a look at the key concepts around medical waste.

Examples of Medical Waste?
1. Anything that is soaked in blood (gloves, gauze, gowns etc.)
2. Human or animal tissues created during procedures
3. Cultures of infectious diseases/agents
4. Any waste produced in patient’s rooms with communicable diseases
5. Discarded vaccines

Definition of Medical Waste

Medical waste is any kind of waste that contains infectious material (or material that’s potentially infectious). This definition includes waste generated by healthcare facilities like physician’s offices, hospitals, dental practices, laboratories, medical research facilities, and veterinary clinics.

Medical waste can contain bodily fluids like blood or other contaminants. The 1988 Medical Waste Tracking Act defines is as waste generated during medical research, testing, diagnosis, immunization, or treatment of either human beings or animals. Some examples are culture dishes, glassware, bandages, gloves, discarded sharps like needles or scalpels, swabs, and tissue.

Different Names for Medical Waste

Medical waste goes by several names that all have the same basic definition. All of the terms below refer to waste created during the healthcare process that’s either contaminated or potentially contaminated by infectious material.

  • Medical Waste
  • Biomedical Waste
  • Clinical Waste
  • Biohazardous Waste
  • Regulated Medical Waste (RMW)
  • Infectious Medical Waste
  • Healthcare waste

The terms are used interchangeably, but there’s a distinction between general healthcare waste and hazardous medical waste. The WHO categorizes sharps, human tissue, fluids, and contaminated supplies as “biohazardous,” and non-contaminated equipment and animal tissue as “general medical waste.”

In fact, office paper, sweeping waste, and kitchen waste from healthcare facilities is still technically medical waste, though it’s not regulated and not hazardous in nature.

Medical Waste Types

The term “medical waste” can cover a wide variety of different byproducts of the healthcare industry. The broadest definition can include office paper and hospital sweeping waste. The list below displays the most common waste categories as identified by the WHO.

  • Sharps. This kind of waste includes anything that can pierce the skin, including needles, scalpels, lancets, broken glass, razors, ampules, staples, wires, and trocars.
  • Infectious Waste. Anything infectious or potentially infectious goes in this category, including swabs, tissues, excreta, equipment, and lab cultures.
  • Radioactive. This kind of waste generally means unused radiotherapy liquid or lab research liquid. It can also consist of any glassware or other supplies contaminated with this liquid.
  • Pathological. Human fluids, tissue, blood, body parts, bodily fluids, and contaminated animal carcasses come under this waste category.
  • Pharmaceuticals. This grouping includes all unused, expired, and/or contaminated vaccines and drugs. It also encompasses antibiotics, injectables, and pills.
  • Chemical. These are disinfectants, solvents used for laboratory purposes, batteries, and heavy metals from medical equipment such as mercury from broken thermometers.
  • Genotoxic Waste. This is a highly hazardous form of medical waste that’s either carcinogenic, teratogenic, or mutagenic. It can include cytotoxic drugs intended for use in cancer treatment.
  • General Non-Regulated Medical Waste. Also called non-hazardous waste, this type doesn’t pose any particular chemical, biological, physical, or radioactive danger.

Medical Waste Facts

The list below gives a quick overview of the topline facts around medical waste, including quantity, breakdown, dangers, and how the waste gets treated.

Quantity. U.S. hospital create an estimated 5.9 million tons of biohazardous and other medical waste every year. That’s 33 lbs of waste per staffed bed every single day.

Breakdown. 85% of all medical waste is deemed non-hazardous and general. The other 15% is hazardous and may be either infectious, radioactive, or toxic.

Danger. Biohazardous waste can contain harmful microorganisms that can infect healthcare workers, patients, and the general public.

How it’s treated. Healthcare waste can be treated on-site or off-site, by truck service or by mail. It can be incinerated, autoclaved, microwaved, or treated by chemical or biological means.

Where Medical Waste Gets Disposed Of

There are several medical waste disposal methods healthcare providers can choose from. The first question is where the waste gets disposed of: on-site or off-site? The second is how the waste gets transported if it’s disposed of off-site.

On-Site Treatment

The on-site treatment of medical waste is generally limited to large, well-monied hospitals and facilities. On-site treatment is extremely cost-prohibitive. That’s because the required equipment is expensive to buy, expensive to maintain, and expensive to manage and run. The regulatory maze around such equipment (and its use) presents yet another barrier to entry.

Off-Site Treatment

Off-site medical waste treatment is a far more cost-effective option for most small and mid-sized medical practices and facilities. Third-party vendors whose main business is healthcare waste collection and disposal have the equipment and training needed to handle the process. Vendors can collect the waste either by truck or by mail.

  • Truck services require a contract with a specially licensed disposal company to haul the waste away for regular destruction. The waste is hauled in special containers to a dedicated disposal facility.
  • Mail or box services use the U.S. Postal Service to ship the waste safely to a facility for treatment. This is generally the most cost effective of all the methods. It requires a vendor fully versed and experienced in all special Postal Service regulations and best practices.

Medical Waste Treatment Methods

No matter where medical waste is processed, it’s ultimately treated by incineration, autoclaving, microwave, biological, or chemical treatment. Incineration, once by far the most popular method, has decreased in usage since the 1990’s, as regulation has forced other methods to come online.

Incineration. Before 1997, over 90% of all infectious medical waste was disposed of by incineration. Changes to EPA regulations has led providers to seek other disposal means. This is still the only method used on pathological waste, for example body parts and recognizable tissues.

Autoclaving. Steam sterilization renders biohazardous waste non-infectious. After it’s been sterilized, the waste can be disposed of normally in solid waste landfills, or it can be incinerated under less-stringent regulation.

Microwaving. Another way to render hazardous healthcare waste non-hazardous is to microwave it with high-powered equipment. As with autoclaving, this method opens up the waste to normal landfill disposal or incineration afterward.

Chemical. Some kinds of chemical waste may be neutralized by applying reactive chemicals that render it inert. This is generally reserved for waste that’s chemical in nature.

Biological. This experimental method of treating biomedical waste uses enzymes to neutralize hazardous, infectious organisms. It’s still under development and rarely used in practice.

Best Practices for Medical Waste Handling

Healthcare workers can avoid most medical waste problems by adhering to a few key best practices. Employees should know the laws, then classify and separate all waste by type into the correct, color-coded waste containers. Waste should be labeled depending on its category, and the right documentation should accompany all containers during transit. A dependable medical waste disposal company can help a facility put these best practices to work.

  • Know the healthcare waste laws. Healthcare waste is regulated by the DOT, EPA, OSHA, and the DEA. It’s vital to be aware of all guidelines from each agency when preparing, transferring, and disposing of hazardous waste.
  • Classify medical waste correctly. Identifying the kind of waste you’re dealing with is the first step in properly disposing of it. Avoid putting non-hazardous waste in with the rest to prevent overspending.
  • Separate the waste by type. Waste should be separated out into the different categories, including sharps, pharmaceutical, chemical, pathological, and non-hazardous. Regulated medical waste goes in red bags. Sharps that go into these bags must be put into puncture-proof containers first.
  • Use the right medical waste containers. Put all waste in approved containers depending on how it’s classified. Some waste can go in certified cardboard boxes, while other waste gets put in special tubs or even locked up for transit.
  • Prepare the containers properly. Healthcare waste containers and bags must be taped for shipment, then packaged according to DOT weight restrictions. Containers should be stored in a secure, dry area before pickup or shipping. It’s essential to properly label all waste before transport as well.
  • Include the right documentation. Proper documentation of healthcare waste is crucial to protect both the provider and the waste disposal company. The right paperwork should accompany each container and bag throughout the process.
  • Use the medical waste disposal color code. The color coding system for waste segregation calls for all sharps to go in puncture resistant red biohazard containers. Biohazard waste goes in red bags and containers. Yellow containers are for trace chemo waste, while pharmaceutical waste goes into black containers for hazardous materials and blue for all others. Radioactive wastes like Fluorine-18 or Iodine-131 get put in shielded containers marked with the radioactive symbol.
  • Hire the right waste disposal company. Multiple regulating bodies, various hazards, and several different kinds of waste present a daunting challenge for healthcare employees. Partnering with a reliable vendor is often vital.

The History of Medical Waste

The approach to handling medical waste in the U.S. has evolved markedly since the 1980’s. In that decade, a series of incidents of healthcare waste washing up on East Coast beaches gained widespread media attention. The events caused calls for increased regulation, which came in the form of 1988’s Federal Medical Waste Tracking Act.

The Act imposed strict rules on the transportation of waste from hospitals and other facilities. When it expired in 1991, the states largely took on the regulatory burden, basing their individual programs on lessons learned from the Act.

New solutions in the medical waste industry continue to offer advancements in security, convenience, cost savings, and speed of service. Among the most useful are a few waste disposal firms that accept waste-transfer by mail.

The Dangers of Medical Waste

Unless it’s managed properly, medical waste can present several health hazards to healthcare employees, waste workers and the general public. Discarded needles can expose us to needle sticks and possible infection if they’re accidentally sent to recycling facilities, or if containers break open in transit. Housekeepers and janitors are also at risk when sharps poke their way out through plastic bags.

Hazardous waste can expose us to microorganisms, radiation burns, poisoning, pollution, and other dangers. Finally, improperly treated waste sent to landfills can contaminate our drinking water and environment.

Who Regulates Medical Waste?

There’s no shortage of medical waste regulation. In the late 1980’s, the waste was overseen by the EPA and the Federal Government. Afterward, regulation passed to the states. State health agencies and environmental programs have information about who governs healthcare waste in each state.

Several federal bodies maintain laws concerning medical waste. These include the Occupational Safety and Health Administration (OSHA), the Centers for Disease Control (CDC), the U.S. Food and Drug Administration (FDA), the Department of Transportation (DOT), and the Drug Enforcement Administration (DEA).

Who Creates Medical Waste?
