Waste from textile industries

Options

A. Methane gas
B. Ethane gas
C. Propane gas
D. Butane gas

Answer

### Step-by-Step Solution

1. **Identify the Waste Produced by Textile Industries**:
- The textile industry primarily produces organic waste, which includes cotton waste. This waste is generated during the processing of textiles, such as cutting, dyeing, and finishing.

2. **Understand the Decomposition Process**:
- The organic waste from the textile industry undergoes decomposition, which is facilitated by bacteria. These bacteria break down the organic materials present in the waste.

3. **Chemical Reaction During Decomposition**:
- During the decomposition process, the organic materials are converted into simpler compounds. The bacteria convert these materials into organic acids, hydrogen, ammonia, and carbon dioxide.

4. **Formation of Biogas**:
- The final stage of this decomposition process involves methanogenic bacteria, which convert the organic acids into biogas. The primary component of this biogas is methane (CH4), along with other gases like carbon dioxide (CO2).

5. **Composition of Biogas**:
- Biogas typically contains about 50-85% methane, 20-35% carbon dioxide, and trace amounts of other gases such as hydrogen (H2), nitrogen (N2), and hydrogen sulfide (H2S).

6. **Conclusion**:
- Therefore, the main gas produced from the waste of the textile industry is methane (CH4), which is harmful to the environment.

### Final Answer
The waste produced by the textile industry primarily results in the formation of methane gas.
