general waste. Figure below presents the<br />

classification of healthcare waste.<br />

<strong>Waste</strong><br />

Infectious waste arises from patients with<br />

infectious diseases such as AIDS, Ebola-<br />

Marburg virus disease and Lassa fever and<br />

also includes cultures and stocks of infectious<br />

agents from laboratory work. Infectious waste,<br />

pathological waste, contaminated sharps and<br />

other contaminated waste from treatment<br />

areas are considered as biohazardous wastes<br />

necessitating special handling and disposal.<br />

Infectious waste, in addition, needs<br />

pretreatment before disposal as biohazardous<br />

waste.<br />

Pathogenic waste from hospitals is classified<br />

under toxic industrial waste. The total amount<br />

of pathogenic wastes generated in 2006 is<br />

approximately 1.4 million litres.<br />

Radioactive waste includes those<br />

contaminated with radionuclide from nuclear<br />

medicine, radio-immunoassay and<br />

bacteriological procedures.<br />
