Waste Compaction

Waste Compaction, Stabilization and Disposal

Compacted Soil, Rock and Ash Blocks

Resonant Shock Compaction LLC licenses its Resonant Shock Compaction (RSC) process for on-site re mediation of contaminated soil, mine waste and other industrial waste. Solidification and stabilization of heavy metals has long been a complex and expensive problem. RSC provides a low cost, high capacity process that achieves about 50% volume reduction. Stabilization is achieved with the addition of chemical binders such as cement, Class C fly ash, phosphates or polymers. Waste materials may be compacted and stabilized into ton-sized blocks that may easily be stored, transported and disposed at an approved site.

RSC is a non-thermal process, however, the blocks can be sintered or vitrified to further improve the environmental stability characteristics.

Disposal of contaminated materials generated during the past industrial and military operations is one of the largest problems facing the world. Billions of dollars will be spent in the U.S. over the next 25 years to remediate radioactive and toxic metals waste left over from the cold war production plants in the DOE complex alone.

Mining waste in the U.S. and throughout the world is a major concern for current and potential environmental damage. RSC volume reduction and stabilization produces strong, durable and low-leaching blocks for disposal. RSC operations could include on-site treatment to meet disposal site requirements, storage, and finally disposal. In some cases the blocks may be used to construct retaining walls or pond liners.

RSC technology provides:

● High throughput (100 tons per 8 hr. shift)
● 50% volume reduction
● Large (1 ton) stabilized waste blocks for disposal
● A non-thermal process and no secondary wastes.
● Low capital and operating costs

The U.S. Department of Energy (DOE) Entrepreneur's Technical Assistance Program has supported RSC applications development at the University of Denver, Environmental Materials Laboratory. Studies included compaction, volume reduction and stabilization of soil containing toxic metals which are representative of waste at many DOE sites. The DOE Argonne National Laboratory also evaluated the RSC process in comparison with a laboratory uniaxial press. Soil and ash samples were spiked with toxic metals and a proprietary chemical binder added to stabilize the metals. Volume reduction, compressive strength, density and leach resistance of the compacted products were compared. RSC
products were generally equal to or better than laboratory uniaxial pressing, however, only RSC can uniformly compact one ton blocks.

RSC LLC and its partners will design, build and license RSC plants for on-site treatment. The company has had discussions with potential partners to install the RSC technology at DOE sites. Please contact us for more information.
