Which of these types of waste does not fall under the category of MSW?

The correct answer is medical waste. Municipal Solid Waste (MSW) generally refers to waste generated from residential, commercial, and institutional sources, which includes items discarded by households, businesses, and public facilities.

Medical waste specifically refers to waste generated from healthcare facilities, such as hospitals, clinics, and laboratories. This type of waste includes materials that could be infectious, hazardous, or otherwise dangerous, which means it is handled differently than typical MSW due to strict regulations concerning its disposal.

On the other hand, commercial, household, and institutional wastes all originate from or are associated with typical urban activities and can be categorized under MSW. Commercial waste comes from businesses, household waste comes from individual residences, and institutional waste pertains to materials from places like schools and government buildings. These types of waste share similar characteristics and disposal processes, differentiating them from specialized waste streams like medical waste.
