Multi-Fuel Flexibility

One System.
Any Fuel.

The X-150 is engineered for mixed multi-fuel operation — converting agricultural residues, municipal waste, industrial by-products, and woody biomass into clean syngas. Over 11 feedstocks tested and validated.

Why Multi-Fuel
Changes Everything

Most gasification systems are designed for a single, homogeneous fuel — typically clean wood chips. The moment you introduce moisture variation, mixed composition, or non-standard feedstocks, they fail.

The X-150 was designed from the ground up for real-world waste streams. AI-assisted process control continuously adapts air flow, temperature zones, and residence time to handle whatever you feed it — from dry coconut shells to wet sewage sludge.

No fuel pre-sorting required for mixed waste streams
Handles moisture content from 5% to 45%
AI-driven real-time parameter adjustment
Seamless fuel switching without shutdown
Consistent syngas quality across fuel types

Fuel Categories

Every fuel listed below has been physically tested in the X-150 gasification system. Fuels marked with the COMETHA badge were tested during the Paris COMETHA project.

COMETHA Paris — Tested in Project
Additional Validated Fuels

Agricultural Waste

Crop residues and agricultural by-products that are abundant, renewable, and often left unused or burned in open fields — creating both a waste problem and an energy opportunity.

Straw

Cereal straw (wheat, barley, rye) — one of the most abundant agricultural residues in Europe. Successfully gasified in collaboration with Hochschule Zittau-Görlitz.

Empty Fruit Bunches

Palm oil processing waste — a massive feedstock in Southeast Asia. Over 20 million tonnes produced annually in Indonesia and Malaysia alone.

Coconut Shells

Hard, dense biomass with excellent gasification properties. High fixed carbon content produces a clean, energy-rich syngas.

Post-Biodigester Residue

COMETHA

The solid fraction remaining after anaerobic digestion. Typically landfilled or spread on fields — the X-150 converts it into additional energy, closing the loop.

Municipal Waste

Everyday waste streams from cities and communities that would otherwise go to landfill or incineration — turned into clean energy at the point of generation.

Municipal Solid Waste (MSW)

COMETHA

Mixed household and commercial waste. The X-150's multi-fuel capability handles the heterogeneous composition that defeats single-fuel systems.

Sewage Sludge

COMETHA

Dewatered residue from wastewater treatment. A growing disposal challenge for municipalities — the X-150 converts it into energy while reducing volume by over 90%.

Industrial & Processing Waste

By-products from manufacturing and processing industries that carry significant disposal costs — converting a liability into an energy asset.

Mixed Plastics

COMETHA

Non-recyclable plastic fractions that cannot enter mechanical recycling streams. Gasification recovers the embedded energy without producing dioxins.

Fiber Boards

COMETHA

MDF, HDF, and particle board waste from furniture manufacturing and construction demolition. Contains resins and adhesives that make conventional recycling impossible.

Horse Manure

COMETHA

Equestrian facility waste mixed with bedding material. A consistent, year-round feedstock in regions with significant equestrian activity.

Woody Biomass

Traditional and well-understood gasification feedstocks that serve as the baseline reference for X-150 performance calibration.

Wood Chips

COMETHA

The standard reference fuel for downdraft gasification. Consistent particle size and moisture content make it ideal for system calibration and baseline testing.

Waste Wood

COMETHA

Treated and untreated wood from construction, demolition, and industrial sources. Categories A1–A4 depending on contamination level.

Research Spotlight

Straw Gasification at
Hochschule Zittau-Görlitz

In February 2021, researchers at the Institute for Process Technology (IPM) at Hochschule Zittau/Görlitz published their findings on straw gasification — part of the HORA project (Hochtemperaturkonversion von Rest- und Abfallstoffen für Energiedienstleistungen), funded by the Sächsische Aufbaubank (SAB).

The research team — led by Schneider, Grusla, Hofmeister, Pohl, and Zschunke — demonstrated that cereal straw, one of Europe's most abundant agricultural residues, can be effectively gasified in downdraft systems. This is significant because straw has historically been considered a difficult feedstock due to its high ash content, low bulk density, and tendency to form clinkers at high temperatures.

Their work validated that with proper air staging and temperature control — capabilities built into the X-150's AI-assisted process management — straw becomes a viable, high-volume feedstock for decentralized energy generation. For regions where straw is routinely burned in open fields (contributing to air pollution and CO₂ emissions), this represents a direct path from waste to clean energy.
