Abstract
Abstract: Vitrification of Hazardous Wastes
Using a Mobile Unit:
An Evolving Technology
By
Due to the increasing environmental and economic restrictions affecting the disposal of hazardous wastes, alternatives to processes such as landfill and incineration are needed to meet the needs of industry and governmental agencies. Vitrification technology offers and environmentally safe as well as an economically attractive alternative.
Environmental
Waste
Vitrification Inc. has developed a
mobile vitrification service to pyrolize all types of hazardous
toxic
waste
into a glass end product. Typical incineration
methods use oxygen for combustion and leave behind a
hazardous, toxic and leachable ash end product. The
vitrification process traps hazardous
waste
in a glass matrix
at a molecular level in a controlled plasma arc torch
furnace. The end product will have the consistency of either
thermally shocked granulated aggregate which can be sold
to glass companies as feed stock or as glass bricks for use in
the construction industry.
Glass products have included toxic constituents for
thousands of years, containing concentrations of lead,
arsenic, heavy metals, etc. (depending upon the color and
quality of the glass desired for the product). These uses of
glass within our homes and businesses have not threatened
our existence, due to the inert nature of glass. The
vitrification process allows the conversion of toxic
waste
streams into a useful product which can be recycled back
into feed stock or into the environment.
The mobile unit used by EWV in the vitrification
process can be brought on-site where wastes are generated
and allows the elimination of hazardous products without
transport or burial of the wastes off-site. This process is
exempt from many of RCRA permitting procedures for
storage, transport and disposal of hazardous wastes, along
with giving the facility the capacity to operate using recycling
technologies. The exposure to liability is greatly reduced
due to cutting out a potential third-party mishandling of the
hazardous
waste
streams.
The cost savings per ton should be dramatic for all
different
waste
streams over transport and disposal of
hazardous wastes by incineration or dumping in permitted
landfills, not to mention the savings from costs of ongoing
liability. The facility can be viewed by the general public as
performing a clean-up operation as compared to simply
burying the product or converting it to another chemical
form which can still produce toxic leachate.
