What characterization defines inorganic waste?

Inorganic waste is characterized by its mineral origin and the presence of chemical substances that do not originate from living organisms. This includes materials such as metals, salts, and minerals, which do not contain carbon-hydrogen bonds typical of organic compounds. Understanding this definition is crucial in wastewater treatment, as inorganic wastes often require different treatment approaches compared to organic wastes.

In contrast, the other options represent organic materials derived either from plants or animals, or they describe biodegradable organic compounds. These materials are primarily composed of organic carbon and are subject to biological decomposition, which distinguishes them from inorganic substances. Recognizing the difference between organic and inorganic waste types is essential in identifying appropriate treatment methods in wastewater treatment processes.
