How to Start a Biogas Plant Startup in India: Complete Step-by-Step Guide (2026)

Starting a biogas plant startup in India is a smart business idea that combines renewable energy, waste management, and steady income. With strong government support, rising fuel costs, and increasing focus on sustainability, biogas plants are becoming highly profitable for entrepreneurs, farmers, and MSMEs.

This guide explains how to start a biogas plant business in India, including cost, subsidies, registration, licenses, plant types, and profit potential.

What Is a Biogas Plant?

A biogas plant converts organic waste such as cow dung, food waste, agricultural residue, and sewage into biogas (methane) through anaerobic digestion.
The gas is used for cooking, electricity generation, CNG (bio-CNG), and industrial fuel, while the leftover slurry becomes organic fertilizer.
