Manufacturing Contractors, Inc, (MCI) is a specialty manufacturer of plastic and steel products with two (2) long term customers, the Department of Energy, (DOE) servicing the nuclear waste liner needs of various nuclear waste sites around the country. The ‘roto-molded’ polyethylene product(s) are used to meet UN Accord requirements for the disposal of certain nuclear waste and protect the steel drums utilized as required and ultimately buried at the DOE – WIPP facility in Carlsbad NM. The other customer, the USDA, for whom MCI makes ‘injection molded’ plastic seed trays; for the long term storage of genetic agricultural seeds, which happens once every 12 to 14 months, when we produce between 2,000 and 3,000 trays.

The initial DOE contract issued in 2006 to CMC, a trade name, was later transferred to MCI as a new corporation in 2009 created to expand into steel fabrication. Periodically, over the years we have designed, engineered and produced specialized steel cargo handling equipment and other customized steel products.


During the first five years of our contract for our standard liner there were only two vendors providing the liners to the DOE. The other vendor has since discontinued production leaving MCI presently as the sole source for this product.

The MCI Heavy Duty (HD) Liner was designed and engineered by MCI which owns the only molds in existence for producing this product and its lifting tool and remains exclusive to MCI.
