A solid waste can be categorized as:

• A. Hazardous waste
• B. Non-hazardous waste
• C. All of the above
• D. Military munition waste

Answer: (C)

Solid waste is any material discarded after use, and how it’s managed depends on its characteristics. Some discarded materials are classified as hazardous because they exhibit certain properties (like ignitability, corrosivity, reactivity, or toxicity) or because they appear on a hazardous-waste list. Others do not meet those criteria and are treated as non-hazardous. Military munition waste is a specific subset of solid waste generated from munitions work that often requires special handling due to energetic materials, but it remains a form of solid waste within the broader category. Because solid waste can be hazardous, non-hazardous, or military munition waste, the best answer is that all of the above can be true.
