Worked practice questions

Which component allows municipal solid waste to generate usable energy?

  1. Silica fraction
  2. Lipid content
  3. Lignin polymers
  4. Ash particles
Show answer and solution

Correct answer: B. Lipid content

Municipal solid waste yields usable energy because of the burnable lipid content within discarded items.

Which toxic emissions fell over 99% at modern waste-to-energy facilities?

  1. Carbon aerosols
  2. Radon isotopes
  3. Halon mixtures
  4. Dioxin toxins
Show answer and solution

Correct answer: D. Dioxin toxins

Environmental regulations successfully reduced waste-to-energy dioxin air emissions by more than 99 percent.

What operational technique is applied at landfills to reduce waste volume?

  1. Compacting waste
  2. Chemical flooding
  3. Biological boiling
  4. Aerobic flushing
Show answer and solution

Correct answer: A. Compacting waste

Heavy compactors compress incoming solid refuse to reduce waste volume and conserve landfill space.
