A commercial biogas plant in India is a large-scale renewable energy system that converts organic waste into clean fuel and organic manure. With increasing fuel prices and strict waste management regulations, businesses are actively searching for commercial biogas plant cost in India, industrial biogas plant project report, and Bio CNG plant setup cost to reduce operational expenses.

What is a Commercial Biogas Plant?

A commercial biogas plant for industrial use is designed to process high volumes of biodegradable waste such as:

• Hotel and restaurant food waste
  
  

• Dairy farm waste
  
  

• Poultry litter
  
  

• Agricultural residue
  
  

• Municipal solid waste
  
  

• Food processing waste
  
  

Through anaerobic digestion, this waste is converted into methane-rich gas used for cooking, electricity generation, steam boilers, or upgraded to Bio-CNG.

How Commercial Biogas Plant Works – Step by Step Process

1. Organic Waste Collection

Biodegradable waste is collected and properly segregated from plastics and metals.

2. Shredding and Slurry Preparation

Waste is crushed and mixed with water to form slurry.

3. Anaerobic Digestion Process

The slurry is fed into an airtight digester tank where bacteria break down organic matter without oxygen.

4. Biogas Generation and Storage

Methane gas is produced and stored in a gas holder.

5. Bio-Slurry Output

The leftover digestate is used as nutrient-rich organic fertilizer.

This complete waste to energy biogas plant process ensures maximum gas yield and efficient waste disposal.
