How to Make Bio Gas Plant By Pakistan Science Club  

The Pakistan Science Club offers a comprehensive guide on constructing a DIY biogas plant, enabling individuals to produce renewable energy from organic waste. This project not only provides a sustainable energy source but also serves as an educational tool to understand anaerobic digestion.

Materials Needed:

• 20-liter plastic bottle (serves as the digester)
• Organic waste (such as kitchen scraps or animal manure)
• Water
• Rubber tubing
• Sealant
• Old tire tube (acts as a gas storage tank)

Steps to Construct the Biogas Plant:

1. Prepare the Digester:

   • Clean the 20-liter plastic bottle thoroughly.
   • Drill a hole in the bottle cap to insert the rubber tubing, ensuring an airtight fit.

2. Mix the Feedstock:

   • Combine organic waste with water in a 1:1 ratio to create a slurry.
   • Pour the slurry into the plastic bottle, filling it about two-thirds full to leave space for gas accumulation.

3. Seal the System:

   • Secure the bottle cap with the tubing attached.
   • Ensure all connections are airtight using sealant to prevent gas leaks.

4. Gas Collection:

   • Connect the free end of the rubber tubing to the old tire tube, which will serve as the gas storage reservoir.
   • As the organic material decomposes anaerobically, biogas will be produced and collected in the tire tube.

5. Usage:

   • Once sufficient gas has accumulated, it can be utilized for cooking or lighting by connecting the tire tube to a suitable burner or lamp.
