Waste energy Solution Summary
One ton (2,000 pounds) of moisture-laden, unsorted MSW (garbage) produces 1.5MW when converted through Green Frog Power systems
Combined systems meet 2050 European Union standards for airborne emissions – today.
How Does 1 Ton of MSW = 1.5MW Net?
GFS doesn't use syngas to perpetuate conversion of waste like torch-based gasification systems = more net electricity sent to the grid
GFS uses 75% less electricity vs. other arc-gasifier systems = more net electricity sent to the grid
GFS uses both the heat & BTUs of the syngas to convert to steam/electricity – no need for syngas to be cooled/cleaned prior to combustion = more net electricity sent to the grid
GFS steam-to-condensate process maximizes conversion of heat to electricity = more net electricity sent to the grid
Leading Edge Technology
Compared to earlier plasma-arc decomposition processes, Green Frog Power’s system uses only one-fourth the energy to affect virtually total
decomposition of carbonaceous materials.
Leading Edge Technology
| Incineration | Plasma Torch | GFS | |
|---|---|---|---|
| Net MW per ton | .5MW | 1MW | 1.5MW |
| Waste Reduction | 65% | 83% | 100%* |
| Waste Type | MSW | MSW, Medical, Hazardous | MSW, Medical, Hazardous, Sewage |
| Moisture | Problematic | Problematic | 50%+ preferred |
| Process Temperature | 2,500oF | 4,500oF | 21,000oF–36,000oF |
| Dioxins, toxins and Furans remaining | Yes | Yes | No |
| Additional Air Pollution Controls | Yes(expensive bag houses) | Yes(lime-based scrubbing required) | No(meets 2050 European standards) |
*100% waste reduction is because the inert fly ash and metal slag can be recycled and/or sold.

GFS Gasification System Overview
Next-gen GFS Gasification System being fabricated in Spokane Valley, Wash., USA (pictured left)
Material processed at rate of 3 to 5 tons per hour
Waste passes through photon-induced plasma arc field in center of chamber
Thermal, chemical, photo and ionic reactions break down and separate waste material at molecular level
Inert material cooled and conveyed through bottom, while syngas exits through top
GFS Technology Differentiators
Accepts nonhomogeneous material separate or mixed together MSW, sewage sludge, biomass, tires, computer waste etc.
Moisture content of feedstock is desirable Integration of leachate water or sewage sludge
Decontamination & vitrification of soils and other inerts
Virtually free of airborne emissions -- already meets rigid 2050 European Union environmental standards
Small system footprint -- modular construction and use of existing infrastructure with linear-scaling capacity
Instrumentation & controls allow for millisecond adjustments throughout plant for increased efficiency
