Answer

To determine the incorrect statement regarding e-waste, let's analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding E-Waste**: E-waste refers to electronic waste, which includes discarded electronic devices such as computers, televisions, radios, and mobile phones. These devices often contain materials that are non-biodegradable.

2. **Analyzing Statement 1**: "Recycling is the only solution for the treatment."
- This statement is generally true. Recycling is a primary method for managing e-waste since many components are non-biodegradable and cannot decompose naturally.

3. **Analyzing Statement 2**: "They are buried in landfills or incinerated."
- This statement is also true. E-waste that cannot be recycled is often disposed of in landfills or incinerated at high temperatures.

4. **Analyzing Statement 3**: "The bulk of e-waste is biodegradable."
- This statement is incorrect. E-waste is primarily composed of non-biodegradable materials such as plastics, metals, and glass. Therefore, the bulk of e-waste is not biodegradable.

5. **Analyzing Statement 4**: "Used to recover metals like copper, iron, silicon, nickel, gold."
- This statement is true. Recycling e-waste allows for the recovery of valuable metals and materials, which can be reused in manufacturing.

### Conclusion:
The incorrect statement regarding e-waste is: **"The bulk of e-waste is biodegradable."**
