CBG (Compressed Biogas) Plant Manufacturer in India
Compressed Biogas (CBG) plants convert agricultural residue, cattle dung and organic waste into purified, high-pressure biogas usable as automotive or industrial fuel — part of India's growing waste-to-energy push. Proveg Engineering builds CBG plants from feedstock intake through digestion, purification and compression.
From organic waste to compressed, usable fuel
A CBG plant digests agricultural residue, cattle dung or organic waste in an anaerobic digester, then purifies and compresses the resulting biogas into a high-pressure fuel. Proveg Engineering configures the digestion, purification and compression stages around your feedstock source, volume and intended end-use.
Why choose Proveg for a CBG plant
- Runs on agri-residue, cattle dung or mixed organic waste
- Digestate byproduct usable as biofertilizer input
- Modular design, scaled to available feedstock volume
- End-to-end coverage: digestion, purification and compression
Equipment covered

- Anaerobic Digester — generates raw biogas from organic feedstock
- Biogas Purification / Scrubbing System — removes CO2 and H2S from the raw biogas
- Compression & Storage Cascade — compresses and stores the purified CBG
Production process
- Feedstock collection & pre-treatment
- Anaerobic digestion
- Biogas purification (CO2/H2S removal)

- Municipal / bulk organic-waste processors
The digestate left over from a CBG plant is a valuable input for our Biofertilizer Plants line. View our full product range, or get in touch to discuss a CBG plant project.
CBG Plant FAQs
What feedstock does a CBG plant need to run efficiently?
Agricultural residue, cattle dung, food and other organic waste can be used, either individually or blended. A dependable, consistent feedstock supply is the main factor in sizing and planning a project.
What happens to the leftover slurry / digestate?
The digestate left after biogas extraction is a nutrient-rich byproduct that can be processed into organic fertilizer — see our Biofertilizer Plants page for the equipment used to turn digestate into a saleable fertilizer product.
How is CBG different from ordinary biogas?
Ordinary biogas is used largely as-is, close to where it is generated. CBG is purified (impurities and CO2 removed) and compressed to a high pressure, making it usable as automotive or piped industrial fuel, similar to CNG.
What plant size suits a mid-size dairy or agri-processing unit?
Plant sizing depends on available feedstock volume, consistency of supply and intended end-use of the CBG. Share your feedstock source and volume so the project can be sized accordingly.
