HerbaGas™: Biogas
Re-engineered

A next-gen biogas system built for cleaner inputs, faster deployment, and higher gas yield—without the drawbacks of traditional digestion.

HerbaGas™

What Is HerbaGas? A Biomass System Inspired by Nature’s Best Converter

HerbaGas™ is named after herbivores—nature’s most efficient biogas plants. For millennia, ruminant animals have turned cellulose-rich grass into energy (VFAs), protein, and nutrients—efficiently and cleanly.

HerbaGas™ mimics this principle as a mechanical cow: engineered to digest dry, fibrous biomass and transform it into multiple high-value outputs—renewable gas, carbon-rich by-products, and nutrient recovery. And just like the cow, it runs on low-value plant matter and produces no waste.

Unlike conventional digesters, HerbaGas™ works without food waste, fats, or manure—expanding where and how biomass can be turned into clean energy. It’s modular, containerized, and scalable for rural, industrial, and agricultural deployment.

Digest Anything a Cow Can

Processes cellulose-rich materials and agricultural residues that most systems can’t digest—no taste buds. Unlocks feedstock security from non-food biomass.

Multiple Outputs from One Input

Like a cow, HerbaGas™ turns a single biomass input into multiple outputs—renewable gas, nutrient-rich water, and carbon-based soil enhancers—maximising value with no waste.

The HerbaGas™ Process: From Input to Impact

HerbaGas™ simplifies biogas production into a streamlined, high-performance process. From raw biomass to renewable gas and by-products, each stage is designed for efficiency, speed, and environmental responsibility.

Feedstock Input

HerbaGas™ accepts dry, fibrous biomass such as grasses and crop residues—no manure or nutrient-rich material required.

Hydrolysis

Complex organic matter is broken down through hydrolysis, unlocking energy potential and preparing for efficient gas conversion.

Methanogenesis

Microorganisms convert the hydrolyzed material directly into methane-rich biogas, achieving 80%+ CH₄ content in significantly less time.

Gas Capture

Raw biogas is captured efficiently with minimal odour or effluent. The system’s design ensures low environmental impact and high energy yield.

By-Products

Outputs include carbon dioxide, nutrient water and carbon solids—both valuable in regenerative agriculture and circular economy applications.
