A used dental anesthetic needle is an example of?

Biodegradable waste
Non-regulated waste
Regulated waste
Recyclable waste

The correct answer is: Regulated waste

A used dental anesthetic needle falls under regulated waste on account of its potential for contamination. Biodegradable waste could include items like food waste or paper products that can decompose naturally in a landfill. Non-regulated waste typically includes items like dust, dirt, or personal hygiene products. Recyclable waste refers to materials that can be processed and reused, such as plastic bottles or aluminum cans. None of these options fully encompass the potential hazards of a used dental anesthetic needle, making C the most accurate choice.
