In The Sherlock Society, what is expensive to dispose of properly?

• A. Hazardous waste
• B. Expired food
• C. Old batteries
• D. Recyclable plastics

Answer: (A)

Handling hazardous waste safely and legally is costly because it requires specialized containment, packaging, labeling, licensed transport, and disposal at permitted facilities, along with documentation and training to meet strict regulations. In The Sherlock Society, this combination makes hazardous waste more expensive to dispose of properly than the other items listed. Expired food can usually be discarded as regular trash or composted in many places; old batteries need special handling but are typically managed through designated programs, spreading the cost. Recyclable plastics are processed through recycling streams that, while not free, are generally less expensive than proper hazardous waste disposal. So the item that is expensive to dispose of properly is hazardous waste.
