COURSE OUTLINE

Special wastes are solid wastes that require special handling and generally are

collected, processed recycled and/or disposed of

separately from other wastes.

DEFINITION OF TERMS

Biomedical waste represents a small

proportion (10-15%) of the total volume of waste

generated by health care facilities.

DEFINITION OF TERMS

Biomedical waste (also referred to as “red bag”, infectious, or bio-hazardous wastes) is generally

defined as “infectious and injurious waste originating from a hospital,

medical office, veterinary or hospice care facility.”

DEFINITION OF TERMS

Biomedical wastes;

Paper and Mill wastes;

Agriculture wastes ;

White goods;

Bulky wastes;

Vehicle wastes: Hulks and Auto Fluff;

Tires;

Industrial Process waste or sludge;

Contaminated soils;

Ash;

Asbestos

Animal Carcasses;

Disaster Debris;

EXAMPLES OF SPECIAL WASTES

Human Anatomical Wastes:

Human tissues, organs and body parts but

does not include teeth, hair and nails

EXAMPLES OF BIOMEDICAL WASTES

Animal Wastes consists of all animal tissues, organs, body parts, carcasses, bedding, fluid

blood and blood products, items saturated or dripping with blood, body fluids removed for

diagnosis or removed during surgery, treatment or autopsy, unless a trained person has certifies that the waste does not contain

certain viruses and agents such as Arenaviridae, Bunyaviridae, Filoviridae,

Flaviviridae, Herpsviridae and Poxviridae. This excludes teeth, hair, nails, hooves and feathers


Microbiology Laboratory Waste:

This consists of laboratory cultures, stocks or specimen of

microorganisms, live or attenuated vaccines, human or animal cell cultures used in research and

laboratory material that has come in contact with any of these


Human Blood and Body Fluid Waste:

This consists of human fluid blood and blood products, items saturated or dripping with blood, body fluids contaminated with blood, and body fluids removed for diagnosis during surgery, treatment or autopsy. This

does not include urine or faeces


Waste Sharps:

These are clinical and laboratory materials

consisting of needles, syringes, blades, or laboratory glass

capable of causing punctures or cuts.


1. Write short notes on each of the “Risk

Group 4” Agents

2. Briefly discuss the relationship between special wastes and

Biomedical wastes
