In Kunjpura village, located in Karnal district, Haryana, Aditya Aggarwal and his older brother Amit Aggarwal run Tee Cee Industries, a steel plant set up by their ancestors in 1984. Along with this, they also run a gaushala that houses 1,200 cows that can no longer produce milk.
The cow shelter was manageable but running the steel plant was turning out to be expensive because they spent a whopping Rs 5 lakh every month on electricity
The brothers struck upon an idea. Why not run the factory with the biogas produced from cow dung from the shelter and other gaushalas , along with bio and agri-waste like sewage , etc this led Aditya and Amit to start Amrit Fertilisers, a biogas project, in 2014, without any government support.
Biogas is a mixture of the following gases.

Options

A. Ethane,Carbon monoxide, Nitrogen and Butane
B. Methane,Hydrogen,Carbon dioxide and Nitrogen
C. Butane,Carbon monoxide,Propane and Hydrogen
D. Carbon monoxide,Sulphur dioxide and Hydrogen

Answer

To determine the composition of biogas, we can analyze the information provided in the video transcript and summarize the key points step by step.

### Step-by-Step Solution:

1. **Understanding Biogas Formation**:
- Biogas is produced from the decay of organic matter in a controlled environment, typically through anaerobic digestion. This process involves the breakdown of organic materials by microorganisms in the absence of oxygen.

**Hint**: Remember that biogas is generated from organic materials, and the process requires a controlled environment.

2. **Identifying Components of Biogas**:
- The main gases found in biogas are:
- Methane (CH₄)
- Carbon Dioxide (CO₂)
- Nitrogen (N₂)
- Hydrogen (H₂)

**Hint**: Focus on the gases that are typically produced during the anaerobic digestion of organic matter.

3. **Composition of Biogas**:
- The approximate composition of biogas is:
- Methane: 50% to 75%
- Carbon Dioxide: 25% to 50%
- Nitrogen: 0% to 10%
- Hydrogen: 0% to 1%

**Hint**: Pay attention to the percentages, as they indicate the relative amounts of each gas in biogas.

4. **Evaluating the Options**:
- Now, we can evaluate the options provided in the question:
- Option 1: Ethane, carbon monoxide, nitrogen, and butane
- Option 2: Methane, hydrogen, carbon dioxide, and nitrogen
- Option 3: Butane, carbon monoxide, propane, and hydrogen
- Option 4: Carbon monoxide, sulphur dioxide, and hydrogen

**Hint**: Compare the gases listed in each option with the known composition of biogas.

5. **Selecting the Correct Option**:
- Based on the analysis, the correct option that includes the gases typically found in biogas is:
- **Option 2: Methane, hydrogen, carbon dioxide, and nitrogen**.

**Hint**: Ensure that the selected option contains all the main components of biogas as identified earlier.

### Final Answer:
The correct option is **Option 2: Methane, hydrogen, carbon dioxide, and nitrogen**.
