What is Gasification?
• A thermo-chemical process to produce a clean fuel gas. This is NOT Incineration.
• Feedstock flexible of the life of the equipment
• Can retain and retrofit current equipment to use the gas (boilers, kilns, etc.)
• On demand energy generation• About 95% of what goes in comes
out as fuel gas. The other 5% is a charcoal biochar with many uses.
• Can be adapted for future applications
The clean, efficient conversion of biomass into a combustible fuel gas in an oxygen-starved environment

What Can You “Gasify?”
• Woodchips– Utility trimmings– Scrap pallets/Construction– Bark or waste wood– Commercial waste
• Agricultural and animal waste• Scrap tires and rubber products• Food processing and other manufacturing waste• Switchgrass, miscanthus and other purpose-grown energy crops• Mixtures improve performance

Using The Fuel Gas:
Currently Being Utilized Here and Worldwide
• Electricity: Gas or steam turbines and ORC generators
• Steam: Boiler and community heating systems
• Direct Thermal: Kiln Operations & Sludge Dryers
• Combustion: Industrial thermal oxidizers

Our Difference
• Downdraft gasification provides a simple, clean, proven method of gasification.
• Downdraft is a robust and elegant solution, but was not considered scalable.
• Physics puzzle solved with the internal shapes of the gasifier. PATENTED
• Power dense, modular design.• Low capital cost & low
operating/maintenance

Feedstock Specifications
• Consistent feedstock = consistent gas• Moisture content is key (< 30%)• Feedstock size: ¼” to 4”• Ash content < 10%• Minimum bulk density: 14lbs/ft3
• Low cost waste streams from other processes can greatly improve economics
• Feedstock “Blends” offer further flexibility
