wastes generated by Diagnosis, treatment, and immunization of humans
health care wastes
wastes generated by - Research using laboratory animals geared towards
improvement of human health;

30.36%
in the ph, what % of wastes from health care facilities are general wastes?
69.63%
hospitals generate an average of ___kg of infectious sharps and pathological wastes and __kg of general wastes per bed per day
0.34 —— 0.39
all health care facilities, institution, business
establishment, and other spaces where health care
services are offered with activities or work processes
that generate health care waste.
Health Care Waste Generators
what are the categories of wastes?
- infectious waste
- pathological & anatomical wastes
- sharps
- chemical wastes
- pharmaceutical wastes
- radioactive wastes
- non-hazardous/ general waste
- all wastes suspected to contain pathogens or toxins
in sufficient concentration that may cause disease.
infectious wastes
- Tissue sections and body fluids or organs derived
from biopsies, autopsies, or surgical procedures sent
to the laboratory for examination.
PATHOLOGICAL & ANATOMICAL WASTE
- Waste items that can cause cuts, pricks, or puncture
wounds
SHARPS
Discarded chemical generated during disinfection
and sterilization procedures
CHEMICAL WASTES
Expired, split, and contaminated pharmaceutical
products, drugs, and vaccines including discarded
items used in handling pharmaceuticals
PHARMACEUTICAL WASTES
Wastes exposed to radionuclides including
radioactive diagnostic materials or radiotherapeutic
materials.
RADIOACTIVE WASTES
Wastes that have not been in
contact with communicable or
infectious agents, hazardous
chemicals, or radioactive
substances, and do not pose a
hazard

GENERAL WASTES
what are the seven treatments and disposal of health care wastes?
- pyrolysis
- autoclave
- microwave
- chemical disinfection
- biological process
- encapsulation
- inertization
Thermal decomposition of health care
wastes in the absence of supplied
molecular oxygen in the destruction
chamber where waste is converted into
gaseous, liquid, or solid form.
- PYROLYSIS
The use of steam sterilization to render
waste harmless and is an efficient wet
thermal disinfection process. The usual
setting is at 121C with a pressure of 15v
psi for 15 to 30 minutes.
AUTOCLAVE
Typically incorporates some type of size
reduction device. Wastes are exposed to
microwave that raise the temperature to
100C for at least 30 minutes.
MICROWAVE
Chemicals like Na hypochlorite, Hydrogen
peroxide, peroxyacetic acid, and heated
alkali are added to health care wastes to
kill or inactivate present pathogens. 5% Na
hypochlorite is recommended.
- CHEMICAL DISINFECTION
Uses an enzyme mixture to decontaminate
health care wastes. The technology is
suited for large applications.
BIOLOGICAL PROCESS
Involves filling of containers with water,
adding and immobilizing material, and
sealing the containers. The containers are
filled with plastic foam, sand, and cement
mortar, sealed, and disposed in a landfill.
ENCAPSULATION
Especially suitable for pharmaceutical
waste that involves the mixing of waste
with cement and other substances before
disposal.
- INERTIZATION
