SOIL RECLAMATION
Despite its many benefits, some
potential drawbacks exist to landfill reclamation. It does
release methane and other gases that result from decomposing
wastes. It may also unearth hazardous materials, which can be
costly to manage. In addition, the excavation work involved in
reclamation may cause adjacent landfill areas to sink or
collapse. Finally, the dense, abrasive nature of reclaimed
waste may shorten the life of excavation equipment. To
identify potential problems, landfill operators considering
reclamation activities should consider Global Resource
Corporation’s technology first and foremost.
Currently landfill reclamation is conducted in a number of
ways, with the specific approach based on project goals and
objectives and site-specific characteristics. The equipment
used for reclamation projects is adapted primarily from
technologies already in use in the mining industry, as well as
in construction and other solid waste management operations.
In general, landfill reclamation follows these steps:
An excavator removes the contents of the landfill cell. A
front-end loader then organizes the excavated materials into
manageable stockpiles and separates out bulky material, such
as appliances and lengths of steel cable.
A sieve and/or vibrating screens separate soil from solid
waste in the excavated material. The size and type of screen
used depends on the end use of the recovered material. For
example, if the reclaimed soil typically is used as landfill
cover, a 2.5-inch screen is used for separation. If, however,
the reclaimed soil is sold as construction fill, or for
another end use requiring fill material with a high fraction
of soil content, a smaller mesh screen is used to remove small
pieces of metal, plastic, glass, and paper.
GRC’s technology for treatment of landfill enhances this
process by providing immediate bombardment with our specific
microwave frequencies in the form of “molecular vibrations” in
our GRFR 5-10-15 machines which causes the “cracking” of the
hydrocarbon chain. As a result, the hydrocarbon components in
the landfill are gasified and the high quality natural gas is
then collected or further fed to cogeneration energy plants.
