Competitive Advantages of AST Plasma

• Can handle all kinds of wastes
• Waste can be mixed or comingled
• Handle large items without pre-processing
• Can handle wet waste
• Extruder optimizes syngas chemistry by homogenizing feedstock density.

Analysis of Competitive Processes – Feed System

• No need for air or co-reactants in process
• High energy efficiency – significantly less energy loss than in other processes
• AC electrodes in “brush arc model” so arc does not impinge on refractory
• Generate high power levels – easily 100MW.

Analysis of Competitive Processes – Furnace

• Lower capital cost – equipment is streamlined design
• Lower cost from having single power supply and single stage reactor
• Lower operating costs – graphite electrodes are inexpensive to operate
• Single vessel and no co-reactants or nitrogen all make for very compact footprint
• Large throughput as AST process designed for large applications.

Analysis of Competitive Processes – Finance

• No dioxins or furans in syngas
• Most chemically pure syngas of all processes
• Automated tapping of slag and metals
• High quality slag for making rock wool
• Metals sold as billets to steel industry (can be high quality)
• No combustion, no char, no ash.

Analysis of Competitive Processes – Outputs

• Vessel can operate for long-time without maintenance and no downtime
• Continuous operation with automated electrode feed
• No furnace shutdown required.
