Compressed Biogas

Compressed Biogas

Evaluate compressed biogas projects from feedstock aggregation and digestion to gas upgrading, digestate use and commercial delivery.

Compressed biogas
Understanding the solution

What Is CBG?

Compressed biogas is upgraded biogas produced from anaerobic digestion of suitable organic materials. A viable project requires consistent feedstock, stable biological operation, gas purification and reliable product offtake.

Feedstock supply contracts, contamination control, biological stability, gas quality, digestate use and offtake are material risks. Project viability cannot be inferred only from nominal plant capacity.

Suitable inputs or applications

  • Cattle dung
  • Press mud
  • Food and market waste
  • Municipal organic waste
  • Agro-industrial residues
  • Distillery residues
  • Selected energy crops subject to sustainability
  • Mixed feedstock after compatibility testing

Benefits

Actual outcomes depend on input quality, process configuration, operation, product quality and local conditions.

01

Organic-waste use

Convert suitable organic wastes and residues into useful gas and digestate products.

02

Renewable fuel

Produce upgraded gas that may substitute conventional gaseous fuels subject to quality requirements.

03

Methane management

Capture and use methane that may otherwise be released from unmanaged decomposition.

04

Digestate value

Develop fertiliser or soil-input pathways where composition and regulations allow.

05

Waste-management service

Support industries, farms and institutions with structured organic-waste processing.

06

Rural infrastructure

Create aggregation, logistics and operating activity around local resources.

Project readiness

What We Need

A project cannot be responsibly configured without the following information.

  • Feedstock type, quantity and distance

  • Land and water availability
  • Gas production target
  • Existing laboratory analysis
  • Digestate utilisation plan
  • Gas buyer or dispensing model
  • Grid and utility access
  • Transport and road access
  • Permissions and waste ownership
  • Capital and working-capital plan
  • Operations capability
