Some refractory brick will be accepted by the manufacturer for
re-use in the production of new product(s). Should this be
possible, AND I AM UNABLE TO SPEAK FOR YOUR SPECIFIC CASE, be sure
to comply with any regulations (hazardous waste or otherwise)
which regulate the re-use/recycling of waste materials.
Again, pending regulations and chemical constitutents in the waste
(much more important when a waste is placed directly into the
environment...and this would NOT be acceptable for a hazardous
waste) some alternate uses may include:
1) As an aggregate (which may require processing of the waste to
meet gradation specifications) in road base construction or the
construction of berms.
2) In concrete or asphalt production...again as an aggregate
meeting gradation specs may be necessary.
3) Should the waste be very "clean", use as "clean fill" may be an
option, or use as a pipe line bedding material.
4) Should landfill disposal seem the only way to go, it may be
possible to work with the landfill to use the waste in a few
different ways which may result in free or reduced-cost disposal:
a) As a sub-base in liner construction (would probably require a
permit modification for the landfill, processing of the waste, and
successful comparison to an existing virgin material, both
chemically and physically).
b) As a protective layer over the primary or secondary liner, or
as a bedding material for a leachate collection system. Being
above the liner system MAY reduce the need for the material to be
as clean as virgin material but a permit modification would still
c) As a daily cover material on the working face, which may help
reduce the need for cover soil and associater truck traffic.
d) It's a long shot, but as a layer of "select waste" initially
placed above a liner (usually the first 8 or 10 feet) for
additional liner protection.
Recently, a foundry (steel) operation told us about a process
where liquid argon is used to "blanket" a melt. The argon reduced
O2 and N intake resulting in reduced slag generation and
reportedly increased refractory life. Such a method may be
helpful as a p2 option.
Please let me know if any of these options pan out.
