Compressed Biogas (CBG) Data Tables
The Compressed Biogas (CBG) data tables library brings together 22 structured reference tables for the CBG business — feedstock properties, equipment specs, product yields, cost breakdowns, and regulatory checklists. Compressed Biogas / Bio-CNG — anaerobic digestion, feedstock, upgrading, and SATAT scheme terminology. Use each table to size a plant, brief vendors, or sense-check the numbers on an opportunity you're evaluating. Open any table for the full data with how-to-read notes, key insights, and the methodology behind the figures.

Bio-CNG Production Yield & Output - Expected Bio-CNG yield
Expected Bio-CNG output in kg/day from a 10 TPD plant for five feedstock types — pressmud gives the highest yield at 1,000 kg/day, while cattle dung gives the lowest at 175 kg/day — with vehicle fuelling equivalents for each.
Bio-CNG Production Yield & Output - Quantity Breakdown (Based on 10 TPD Input)
Daily digestate output split into solid Fermented Organic Manure (FOM) and liquid FOM for four feedstock types in a 10 TPD Bio-CNG plant — the numbers a developer needs to plan digestate storage and off-take.
C 2 tables
CBG/ Bio-CNG conversion efficiency & Mass Balance
A complete mass balance for a 10 TPD CBG plant showing how much water is added, how much biogas is produced, and how much digestate exits the digester for five feedstock types — from agri waste to animal waste.
CO-digestion process: Operational Breakdown: Activities & Resources
A four-step operational guide for co-digestion in a CBG plant — combining two or more feedstock types — covering Carbon-to-Nitrogen ratio optimisation, multi-feed mixing, digestion management, and nutrient recovery from the enriched digestate.
D 2 tables
Difference between biogas and compressed biogas
Side-by-side comparison of raw biogas and Compressed Biogas (CBG) covering methane purity, calorific value, impurities, and how each gas is transported — the two states of the same gas after the upgrading step.
Dry digestion process - Operational Breakdown: Activities & Resources
A five-step operational guide for dry anaerobic digestion — the process used for high-solids feedstocks like straw and crop stalks — covering preparation, tunnel loading, leachate-based fermentation, gas capture, and dry digestate discharge.
O 2 tables
Operational Breakdown: Activities & Resources
A five-step operational guide for wet anaerobic digestion in a CBG plant — from pre-processing feedstock to de-sludging the reactor — with the key activities and essential equipment at each stage.
Operational flexibility and limitations
A side-by-side comparison of five CBG feedstock types showing each one's main operational advantage and its hardest practical limitation — the trade-offs a developer must accept when choosing a primary feedstock.
P 2 tables
Pollution Index Classification Table
CPCB Pollution Index classification table for biogas plants — mapping feedstock type, PI score, wastewater generation, and CTO validity (5 or 7 years, or exempt) across RED, BLUE, and WHITE categories.
Process Differences by Feedstock type
A comparison of five feedstock types for CBG plants showing the primary digestion challenge for each and the unique pre-treatment step that addresses it — from lignin-heavy agro-waste to pH-sensitive industrial effluents.
Z 8 tables
Zone 1: Pre-Processing & Feeding (10 TPD Capacity) - Capacity, specification & price ranges
Seven pre-processing and feeding equipment items for a 10 TPD CBG plant — with throughput specifications and indicative procurement price ranges — covering shredders, hydro-pulpers, conveyors, mixing tanks, and feeding pumps.
Zone 2 - Equipment function and application - Core Reactor Technologies
Five anaerobic digester reactor technologies compared by feedstock type, total solids percentage, key design features, and the core advantage of each — a reference for selecting the right reactor for a specific feedstock mix.
Zone 2 - Capacity, specification & price ranges
Seven Zone 2 digestion equipment items for a 10 TPD CBG plant — digester tanks, agitators, biogas storage dome, heating coils, blower, and safety fittings — with capacity specifications and indicative Indian supplier price ranges.
Zone 3 - Gas Cleaning & Upgrading - Upgrading Technologies
Side-by-side comparison of three biogas upgrading technologies — Membrane Separation, PSA, and Water Scrubbing — covering how each works, methane recovery %, power demand, maintenance burden, and startup speed.
Zone 3 - Gas Cleaning & Upgrading Equipments - Capacity, specification & price ranges
Seven Zone 3 gas cleaning and upgrading equipment items for a 10 TPD CBG plant — from H2S scrubber through membrane upgrading unit and online analyzer — with technical specifications and indicative Indian supplier price ranges.
Zone 4 - Compression & Bottling Equipments - Capacity, specification & price ranges
Equipment specifications and indicative price ranges for Zone 4 — the compression and bottling stage of a CBG plant — covering the five main items from the high-pressure compressor to the emergency shut-off system.
Zone 5 - Digestate Management Equipments - Capacity, specification & price ranges
Equipment specifications and indicative price ranges for Zone 5 — the digestate management stage of a CBG plant — covering the seven items that separate, store, dry, and filter digestate into marketable Fermented Organic Manure (FOM).
Zoning Applicability and Compliance
Zoning and buffer zone rules for biogas plants classified as RED, BLUE, or WHITE under CPCB guidelines — showing where each category can be built, how far from residential areas, and what compliance steps are mandatory.
