What is CBG?
Compressed Bio-Gas (Bio-CNG) — from organic waste to clean fuel
CBG is high-purity methane produced by the anaerobic digestion of agricultural residue, cattle dung, press-mud and municipal organic waste. It is a direct drop-in replacement for fossil CNG and industrial LPG — with a nutrient-rich organic fertilizer (FOM / LFOM) as a valuable by-product. One process solves waste management, rural income and clean-energy security together.

CBG production process
1
Feedstock Collection & Pre-treatment
Agricultural residue, cattle dung, press-mud, poultry litter and MSW-organics are collected and pre-treated to remove impurities.
2
Anaerobic Digestion
Organic matter decomposes in an oxygen-free digester, producing raw biogas and nutrient-rich digestate (FOM/LFOM).
3
Purification & Upgradation
Raw biogas is scrubbed of CO₂, hydrogen sulphide (H₂S) and moisture to yield high-purity (>90%) methane.
4
Compression & Cascade Filling
The upgraded Bio-CNG is compressed and filled into cascades for safe storage and dispatch.
5
Offtake & Distribution
CBG is supplied to OMC retail (SATAT), CGD grid injection and industry; FOM is bagged for farms.
Why CBG
Six reasons CBG powers a sustainable future
Concrete environmental, economic and social benefits that make CBG India's most strategic clean-fuel investment.
Cuts Greenhouse Emissions
Captures methane from rotting organic waste — a potent GHG — directly lowering the carbon footprint and earning carbon credits.
Cleaner Air Quality
Burns far cleaner than fossil CNG/diesel — fewer particulates, NOx and toxic emissions for measurable public-health gains.
Uses Local Resources
Turns district-level agri & animal waste into fuel, cutting fossil-fuel imports and enabling genuine energy independence.
Energy Security & Diversification
Adds a home-grown, price-stable fuel to the energy mix — shielded from volatile global oil & gas prices.
Rural Jobs & Farmer Income
Feedstock aggregation creates rural employment and a new income stream for farmers from crop residue & dung.
Multiple Revenue Streams
SATAT CBG offtake + FOM/LFOM at ₹1,500/MT MDA + carbon credits — waste converted into a paying, bankable asset.

Turnkey capacity models — ₹5.00 Cr / TPD + 18% GST

FAQ
Common questions
What is the minimum investment to set up a CBG plant with Ziloxis?
At the ₹5.00 Cr / TPD benchmark, a production-grade 5 TPD CBG plant lands at ~₹25 Cr (+18% GST extra) including civil, digester, upgradation and bottling. A minimum scalable 3 TPD entry is ~₹15 Cr (+18% GST). GOBARdhan capital assistance / state subsidies apply as notified, and a large share is depreciable in Year-1 under accelerated-depreciation (AD) rules.
How long does CBG plant commissioning take?
From Final Investment Decision (FID) to RFSO sign-off: feasibility T+21 days, DPR + SATAT bidding T+45, statutory approvals (MoEFCC + PESO + CGD + PNGRB) T+120-180 days, and plant erection + commissioning T+18-24 months.
Who buys the Bio-CNG and at what price?
SATAT contracts lock in a 15-year offtake with IOC, BPCL and HPCL at a government-fixed ₹54/kg — invoice-settled monthly against delivered volumes. No merchant market exposure.
What feedstocks does Ziloxis work with?
Paddy straw (Punjab · Haryana · UP), sugarcane press-mud (Maharashtra · UP · Karnataka), dairy waste (Gujarat · Rajasthan) and MSW-organics (metro cities). Every DPR includes signed 5-year feedstock MoUs covering ≥120% of nameplate consumption.
Do you handle MNRE GOBARdhan subsidy paperwork?
Yes — SATAT onboarding, MNRE empanelment, GOBARdhan CFA filing and the disbursement claim-cycle are handled in-house. Clients only sign documents; we do the follow-up with each ministry desk.
