Types of Healthcare Waste: Categories, Examples & How Each Is Classified

Healthcare waste is the broad term for all waste generated in the course of providing care. The types of healthcare waste fall into separately regulated streams, and each stream has its own handling, treatment, and disposal requirements.

Regulated medical waste (RMW) is one of those streams. It covers infectious materials only, so the different types of medical waste belong to one subset of healthcare waste: the terms are not simply interchangeable. At SaniTrax, we help healthcare facilities manage each stream safely, responsibly, and in accordance with regulatory requirements.

What Is Healthcare Waste?

Healthcare waste includes materials generated during healthcare operations, from patient care and laboratory work to diagnostic procedures and treatment services. It comes from hospitals, primary care and dental offices, laboratories, research centers, blood banks, nursing homes, and veterinary clinics.

According to the World Health Organization, about 85% of healthcare waste is general, non-hazardous waste comparable to household trash. The remaining 15% is hazardous material that may be infectious, chemical, or radioactive. Regulated medical waste falls within the infectious portion of that share.

What Are the Main Types of Healthcare Waste?

A common way to group healthcare waste is by five major types:

• Infectious waste: Contains materials that may carry pathogens and create a risk of infection.
• Hazardous waste: Includes waste containing chemicals or substances that may be harmful.
• Pharmaceutical waste: Includes expired, unused, partially used, or contaminated medications and pharmaceutical products requiring proper disposal.
• Radioactive waste: Comes from medical procedures involving radioactive materials.
• General waste: Includes non-hazardous materials that do not pose a biological or chemical risk.

Within these five types, facilities separate waste into more specific categories, each with its own containers and disposal route:

Category-by-Category Breakdown

Infectious/Biohazardous Waste (RMW)

Regulated medical waste includes materials that may contain infectious agents. Common items include blood-soaked bandages, laboratory cultures and stocks, and disposable devices contaminated with blood. RMW must be treated before final disposal, and facilities can choose from several biomedical waste management options for that step.

The types of medical waste within this stream also include sharps and pathological waste.

Pathological Waste

Human tissues, organs, and other biological materials removed during medical procedures make up pathological waste. Biopsied tissues and amputated limbs are typical examples. Facilities pack this waste in containers separate from other infectious waste for incineration.

Sharps Waste

Sharps waste includes items that can puncture or cut, such as needles, scalpels, and broken glass vials. These items go into puncture-resistant containers to reduce the risk of injury and exposure. A licensed provider collects full containers through a sharps disposal program.

Pharmaceutical Waste

Expired, unused, and unwanted medications are classified as pharmaceutical waste. Outdated antibiotics and medications returned by patients fall into this category.

Facilities keep pharmaceuticals apart from infectious waste and send them to a pharmaceutical waste disposal program. Sorting by drug comes first, because some medications qualify as hazardous waste and others do not.

Chemotherapy/Trace Chemo Waste

Chemotherapy waste includes items that contain or have touched antineoplastic (cancer treatment) drugs. How it is managed depends on how much of the drug remains in the item.

• Trace chemotherapy waste includes empty drug vials, empty IV bags and tubing, and gloves and gowns used during administration. Under federal RCRA rules, most containers count as empty when they hold no more than 3% of their capacity by weight. Facilities keep trace waste in their own containers and manage it with the infectious stream.
• Bulk chemotherapy waste includes IV bags with leftover medication, partially used vials, and materials from a spill cleanup. It is typically managed as hazardous waste.

Chemical Waste

Chemical waste includes unused reagents, laboratory chemicals, and other hazardous substances. X-ray developer and fixer solutions, formalin, solvents, HPLC waste and disinfectants are common in this category. Through a hazardous waste disposal program, a licensed vendor profiles, packs, and transports it under RCRA rules.

Radioactive Waste

Radioactive waste is generated during procedures involving radioactive materials, such as certain radiotherapy and nuclear medicine treatments. Examples include contaminated gloves and swabs used in these departments.

The Nuclear Regulatory Commission or a state radiation control program regulates this waste. Facilities often keep short-lived materials in controlled storage until they decay to safe levels for disposal.

General/Non-Regulated Waste

General or non-regulated waste includes everyday materials that do not contain hazardous or infectious components. Paper products, office materials, and kitchen waste belong in this category. These materials can typically be managed through standard waste disposal systems.

Is Medical Waste Hazardous Waste?

Regulated medical waste and hazardous waste fall under different regulatory classifications.

RMW is infectious waste. For transport, the U.S. Department of Transportation classifies it as a Division 6.2 infectious substance because of its potential to transmit disease.

Hazardous waste is managed under the EPA’s Resource Conservation and Recovery Act (RCRA). It covers chemicals, certain pharmaceuticals, and other materials that appear on EPA hazardous waste lists or are ignitable, corrosive, reactive, or toxic.

Is Regulated Medical Waste a Hazardous Waste Under EPA Rules?

It is a misconception that regulated medical waste is considered a hazardous waste by the EPA. The EPA’s only effort to track RMW was a two-year demonstration program created by the Medical Waste Tracking Act of 1988, which expired in 1991.

Since then, the states have set most RMW rules. Regulated medical waste remains separate from the EPA’s RCRA hazardous waste program, which focuses on materials that present chemical or environmental hazards.

How Healthcare Waste Is Classified in Florida

In Florida, the Department of Health regulates biomedical waste under Chapter 64E-16 of the Florida Administrative Code. The rule sets requirements for identifying, handling, storing, transporting, and treating biomedical waste generated in the state. Hazardous, radioactive, and general waste from the same facility fall under separate state and federal programs.

Why Correct Classification Matters

Correct classification affects three areas of a facility’s waste program:

• Safety: Proper classification reduces the risk of exposure for healthcare workers, patients, and waste handling professionals.
• Compliance: Misclassified waste can lead to violations and penalties from state and federal regulators.
• Cost: Correct classification prevents facilities from paying for specialized treatment of materials that could go with general waste.

Our medical waste management services include staff training and facility audits that help teams place each type of waste in the correct container.

Frequently Asked Questions

What is the difference between medical waste and biomedical waste?

The two terms are often used interchangeably. Both usually refer to the infectious stream within healthcare waste, generated during diagnosis, treatment, research, or immunization. Some states, including Florida, use “biomedical waste” as the legal term.

When is medical waste most hazardous?

Medical waste poses the greatest risk at the point of generation, when it is freshly contaminated, and pathogen levels are highest. Handling at the point of generation matters most for that reason. That means sharps containers at the bedside, red bags in exam rooms, and secure containment before the waste leaves the room. Risk also rises whenever waste is improperly segregated or handled.

Can pharmaceutical waste go down the drain?

Pharmaceutical waste from healthcare facilities belongs in a disposal program rather than a sink or toilet. The EPA’s Subpart P rule prohibits healthcare facilities from sewering hazardous waste pharmaceuticals, a ban that took effect nationwide in 2019. The EPA also recommends against sewering non-hazardous medications, and controlled substances follow separate DEA requirements.

Are used gloves and gauze regulated medical waste?

They are regulated when they are contaminated enough to meet the definition. OSHA’s Bloodborne Pathogens Standard treats an item as regulated waste when it would release blood or other potentially infectious materials if compressed. Items caked with dried blood also qualify. Gloves and gauze below that threshold can usually go with general waste, though state rules and facility policy may be stricter.

Who is responsible for classifying healthcare waste?

The facility that generates the waste is responsible for classifying it. Under federal RCRA rules, generators must determine whether each waste they produce is hazardous. That responsibility remains with the generator even when a waste vendor handles pickup and disposal.

Do dental offices need to manage amalgam waste separately?

Dental amalgam contains mercury, so it is managed separately from both regulated medical waste and general trash. The EPA’s dental office rule requires most dental practices that discharge wastewater to a public sewer to use amalgam separators. Collected amalgam is typically sent to a recycler rather than placed in red bags or sharps containers.
