ISIT has been researching a powerful new technology called Plasma Gasification. It's a process that converts carbon (organic) materials such as municipal and other wastes, coal, and petroleum into synthesis gas (syngas), under very controlled conditions of heat and oxygen.

There are two primary products: one is SYNGAS, composed of hydrogen and carbon monoxide, which can be used as a fuel to generate electricity or it can be used as a basic chemical building block in the production of high value energy products such as diesel fuel. Depending on the feed stock, the other is molten glass (also metal) that can be used in construction or building materials.

Plasma gasification is NOT combustion and in fact, is very different from combustion or incineration. The chemical reactions in the plasma gasification process converts waste or other materials into simple molecules and atoms, whereas incineration creates complex and toxic substances, including dioxins and furans.

WHY Plasma for Waste to Energy Solutions?

Energy sources which are not harmful to the environment and atmospheric pollution are two of the worlds’ most critical global challenges.

• High temperatures provide different chemistries and chemical kinetics

• Produce higher quality SYNGAS

• Better environmental performance

• Enable efficient processing of wide range of feed stocks (wood, plastic, MSW, medical waste, chemicals, etc)

• Operate efficiently at smaller scale than alternative approaches

• Can be configured for efficient energy production, or production of transport fuels, or chemical feedstocks

• Solid residues are non-leaching vitreous – NOT ASH

This Goal is Not New.

Economic Waste to Energy Conversion Requires Efficient Heat Sources

For years, plasma scientists have attempted to commercialize direct current plasma generators for convertIng waste to energy.

Plasma waste to energy gasification facilities have been built in Europe and Asia, where land filling is very limited or even prohibited and energy has historically been more costly.

The critical limitation to successful implementation of these plasma gasification facilities, has been the lifetime of the plasma generators and the efficiency and associated economics of the gasification process. The first generation of torches were DC, now they are AC.

High Efficiency Alternating current Current Plasma Generators were developed by the Russians during the Cold War. This technology has been transitioned to the United States and ISIT.
