    About Startech -- The Environment and Energy Company

    Startech Environmental is an environment and energy
industry company engaged in the production and sale of its
innovative, proprietary plasma processing equipment known
as the Plasma Converter System(TM).  

    The Plasma Converter System safely and economically
destroys wastes, no matter how hazardous or lethal, and
turns most into useful and valuable products. In doing so,
the System protects the environment and helps to improve
the public health and safety. The System achieves
closed-loop elemental recycling to safely and irreversibly
destroy Municipal Solid Waste, organics and inorganics,
solids, liquids and gases, hazardous and non-hazardous
waste, industrial by-products and also items such as
"e-waste," medical waste, chemical industry waste
and other specialty wastes, while converting many of them
into useful commodity products that can include metals and
a synthesis-gas called Plasma Converted Gas (PCG)(TM).

    Among the many commercial uses for PCG, is its use to
produce "green electrical power," Gas-To-Liquid
(GTL) fuels such as ethanol, synthetic diesel fuel and
other higher alcohol "alternative" fuels. 
Hydrogen, for use and sale, can also be separated and
recovered from the PCG synthesis gas mixture.

    The Startech Plasma Converter is essentially a
manufacturing system producing commodity products from
feedstocks that were previously regarded as wastes. 

    Startech regards all wastes, hazardous and
non-hazardous, as valuable renewable resources.
