As India continues to shift toward renewable energy and waste-to-energy solutions, bio domes (also called biogas holders or biogas balloons) have become a critical component in modern biogas plant infrastructure. These domes store methane-rich biogas generated from organic substrates, making them essential for maintaining consistent pressure, safety, and efficiency.

However, not all bio domes are created equal and the fabric material used directly impacts lifespan, safety, gas retention, and cost-efficiency. This is where PVC coated fabrics have emerged as the industry standard for high-performance biogas storage systems.

In this blog, we break down why PVC coated fabric matters for bio domes, and what makes LUCKY-TECH MEMBRANES , in exclusive partnership with Sioen Industries, Belgium , a trusted choice for India’s biogas infrastructure.

What Are Bio Domes in Biogas Plants?

A bio dome, often referred to as a:

• Biogas holder
• Biogas balloon
• Gas storage dome
• Flexible gas holder

…is an inflatable, flexible membrane installed on digesters or as stand-alone storage units to hold processed biogas.

Their design needs to withstand:

✔ Constant gas pressure
✔ UV exposure
✔ Temperature variations
✔ Microbial gases (methane, CO₂, H₂S)
✔ Mechanical stress

Choosing the right membrane fabric is crucial for performance and safety.

Why PVC Coated Fabric Is the Best Choice for Bio Domes

Here’s why leading biogas manufacturers rely on PVC coated fabric for domes and gas holders:

1. Superior Gas Tightness
PVC membranes offer excellent impermeability, helping maintain:

✔ Gas purity
✔ Pressure stability
✔ Reduced leakage risk

This ensures higher plant efficiency and predictable energy output.

2. UV & Weather Resistance
Bio domes are continuously exposed to:

• Harsh UV rays
• Rainfall
• Humidity
• Dust
• Temperature shifts

PVC-coated membranes can withstand Indian climatic extremes without material fatigue.

3. Chemical Resistance to Biogas Compounds
Biogas contains corrosive gases like Hydrogen Sulfide (H₂S). PVC-coated fabrics resist gas-induced degradation, extending lifespan significantly.

4. Reinforced Mechanical Durability
With added polyester mesh reinforcement, PVC fabrics provide:

✔ High tear resistance
✔ Tensile strength
✔ Dimensional stability

This prevents balloon ruptures and membrane stretching over years of operation.

5. Longer Lifespan & Cost Efficiency
A high-quality PVC coated bio dome can easily last 10–15+ years when maintained properly — reducing plant downtime and replacement costs.
