What does the term "e-waste" encompass?

The term "e-waste" specifically refers to discarded electronics and electrical devices, making the choice focused on this definition the correct answer. E-waste includes a wide variety of items such as old computers, televisions, smartphones, and other electronic appliances that are no longer in use. This category is significant because it poses particular environmental concerns due to the harmful substances often found in electronics, such as lead, mercury, and cadmium, which can cause pollution and health risks if not disposed of properly.

The other options do not fall under the definition of e-waste. Food waste from restaurants pertains to organic waste and is unrelated to electronics. Plastic waste from packaging is associated with materials that are single-use or non-biodegradable but does not include electronic items. Hazardous chemical waste involves materials that are dangerous to human health and the environment but does not specifically apply to discarded electronics. By focusing on the correct definition, it is clear why the inclusion of discarded electronics and electrical devices is central to understanding e-waste.
