Frequently Asked Questions

1. What feedstock can I plan for my BioCNG plant

Biogas can be generated from any organic matter. Cow dung is the mother source of the Archea Methanogen. Any mix of raw material that gives year-round availability at the right price and right quality and quantity makes the plan techno commercially viable.

2. Can we plan mix feedstock as input for the biogas plant?

Absolutely yes.

3. How much time does it take to setup a BioCNG plant?

A typical 5 TPD plant takes about 10-12 months from the time of ground breaking to commissioning and first dispatch of Compressed Biogas.

4. What is the ideal capacity of the plant that I need to setup?

A minimum viable plant size is 3TPD output. 5-10 TPD plant can be comfortably operated and managed.

5. What is the typical composition of raw biogas and what purity is needed for CBG?

Raw biogas often has roughly 55-60% methane (CH₄) and 35-40% CO₂, plus some H₂S, moisture and other trace gases. For CBG/vehicle fuel/pipeline use, the methane content needs to be high (e.g., >90-95%) and impurities (H₂S, siloxanes, moisture) need to be reduced significantly.

6. What are the key process components in a Compressed biogas plants?

Feedstock handling and preparation (shredding, grinding, water mixing, homogenization).

Anaerobic digestion / biogas generation in digesters.

Biogas cleaning & upgrading: H₂S removal, CO₂ removal or reduction, drying, other impurity removal.

Compression of upgraded gas to high pressure( 200-250 bar) or injection into pipeline (7-15 bar).

By-product management: digestate/slurry used for fertilizer or soil amendment.

7. What incentives / policies exist (in India) for CBG?

The MoPNG SATAT scheme (Sustainable Alternative Towards Affordable Transportation) aims to promote CBG plants and fuel. Other supports: priority sector lending for CBG projects, subsidies for certain parts, policy push for waste-to-fuel projects through MNRE
