Small quantity of industrial toxic waste is removed by

Options

A. Burning in open bins
B. Controlled incineration
C. Burning in closed bins
D. Both (1) & (2)

Answer

To answer the question "Small quantity of industrial toxic waste is removed by," we can follow these steps:

### Step 1: Understand the context of the question
We need to identify methods for removing small quantities of industrial toxic waste. Toxic waste can be hazardous and requires careful handling.

**Hint:** Consider the methods typically used for waste disposal and their suitability for small quantities.

### Step 2: Identify possible methods of waste removal
Common methods for removing toxic waste include:
- Incineration (burning)
- Chemical treatment
- Landfilling
- Recycling
- Neutralization

**Hint:** Think about which methods are practical for small quantities versus large quantities.

### Step 3: Evaluate the methods
- **Incineration in closed bins:** This method is generally used for large quantities of waste, as it requires a controlled environment to manage emissions and heat.
- **Incineration in open bins:** This method can be used for small quantities of waste, as it allows for easier disposal without the need for complex systems.
- **Chemical treatment and neutralization:** These methods can also be effective but may not be as straightforward for small quantities.
- **Landfilling:** Not suitable for toxic waste due to potential leaching and environmental hazards.

**Hint:** Focus on the practicality and safety of each method for small quantities.

### Step 4: Choose the most appropriate method
Given the options, burning in open bins is the most suitable method for removing small quantities of industrial toxic waste. This method allows for direct and immediate disposal, although it must be done with care to minimize environmental impact.

**Hint:** Consider the implications of each method on the environment and safety.

### Final Answer
The correct answer to the question is **burning in open bins**.
