Client: Bechtel Hanford Company
Waste Treated: Asbestos
Project Initiated: December 1996
Project Completed: September 1997
Project Goal: Validate technology for asbestos destruction
pursuant to 40 CFR 61.155
The
Department of Energy at Hanford contracted with ARI Technologies
through their prime contractor Bechtel Hanford for ARI to
provide a thermochemical conversion Unit (TCCU) and use it
to destroy asbestos. The project required that the demonstration
be performed in accordance with the National Emission Standard
for Hazardous Air Pollutants (NESHAP) requirements for Asbestos
Conversion Processes, 40 CFR Subpart M, 61.155.
ARI
performed under this contract for a period of 9 months from
December 1996 until September 1997. During this time, ARI
processed a variety of DOE asbestos-containing materials (ACM)
including pipe lagging, asbestos-contaminated soil, asbestos-containing
vinyl tiles, transite, and duct insulation.
Processing
rates for the ACM ranged from 300 to 600 lb. per hour and
the end products were tested for presence of asbestos and
for physical properties. As required by EPA protocols, the
project involved 90 days of process sampling. All of the product
produced by the project was certified to be 100% asbestos
free and was found to have suitable physical properties to
be used in construction applications such as roadbed gravel.
The volume of the waste was reduced an average of 70%.
An evaporator was used to reduce the quantity of blow-down
water from the particulate scrubber system thus minimizing
the quantity of secondary waste produced by the system. The
DOE estimated that the asbestos conversion program will reduce
costs by $2.9 million by eliminating landfill expansion.
The
successful project resulted in the US EPA granting approval
of ARI's TCCT
as an accepted method for destruction for asbestos. In addition,
ARI was granted approval to construct multiple processing
units for deployment and operation.
