Commercial Biogas Plant in India: Cost, Working Process, Benefits and Profitability

A commercial biogas plant in India is a large-scale waste-to-energy system that converts organic waste into clean biogas and organic fertilizer. With rising fuel prices and strict environmental regulations, industries are increasingly investing in industrial biogas plants to reduce operational costs and manage waste efficiently.

This guide covers the working process, plant cost, benefits, return on investment, and frequently asked questions.

What is a Commercial Biogas Plant?

A commercial biogas plant is designed to process large quantities of biodegradable waste such as:

Food waste from hotels and restaurants

Agricultural waste

Dairy and poultry waste

Municipal organic waste

Food processing industry waste

The plant converts this waste into methane-rich biogas through anaerobic digestion. The gas can be used for cooking, electricity generation, steam production, or upgraded to Bio-CNG.

How a Commercial Biogas Plant Works

The plant operates on the anaerobic digestion process. Below is the step-by-step process:

1. Waste Collection and Segregation

Organic waste is collected and separated from non-biodegradable materials.

2. Shredding and Slurry Preparation

The waste is crushed and mixed with water to form slurry.

3. Anaerobic Digestion

The slurry is fed into an airtight digester where bacteria break down organic matter in the absence of oxygen.

4. Biogas Production and Storage

Methane gas is produced and stored in a gas holder.

5. Bio-Slurry Output

The remaining digestate is removed and used as high-quality organic manure.
