Which one of the following is not a non biodegradable industrial waste?

Options

A. Gypsum from fertilizer industries
B. Mud and tailings from metal industries
C. Slag from steel industries
D. Waste from textile industries

Answer

To determine which of the following is not a non-biodegradable industrial waste, we first need to understand the definitions of biodegradable and non-biodegradable materials.

### Step 1: Define Biodegradable and Non-Biodegradable Waste
- **Biodegradable Waste**: This type of waste can be broken down by microorganisms, air, moisture, and soil into simpler, natural compounds. Examples include fruit and vegetable peels, eggshells, and paper.
- **Non-Biodegradable Waste**: This waste cannot be broken down by natural processes and takes a long time to decompose. It can be harmful to the environment. Examples include plastics, metals, glass, and certain chemicals.

### Step 2: Analyze the Options
Now, we need to analyze the options provided in the question to identify which one is not a non-biodegradable industrial waste.

1. **Plastics**: Known to be non-biodegradable.
2. **Gypsum**: Used in cement, also non-biodegradable.
3. **Glass Objects**: Non-biodegradable as they do not decompose naturally.
4. **Waste from Textile Industries**: This is where we need to focus. Textile waste can include natural fibers such as cotton, silk, and wool, which are biodegradable.

### Step 3: Conclusion
Based on the analysis:
- The waste from textile industries is primarily biodegradable because it consists of natural fibers that can decompose over time. Therefore, it is not classified as non-biodegradable industrial waste.

### Final Answer
The correct answer is **Waste from Textile Industries**, as it is not a non-biodegradable industrial waste.
