Description:

CDC Coatings/Dickson Weatherproof Nail Co. uses zinc metal in a proprietary galvanizing process to coat the various metal fasteners that are manufactured. A waste stream is generated, as a result of this galvanizing process, in the form of pellets that varying in size 1/8" to 1/2" in diameter. These waste pellets have a high zinc metal content.

P2 Application:

Several attempts in the past have not been successful in locating domestic sources for recycling or reclaiming the zinc metal contents of the waste stream. An international source was located that was willing to reclaim the zinc and pay CDC Coatings/Dickson Weatherproof Nail Co. a portion of the original material cost for this waste stream. An acid reduction and electro-plating process will be used to recapture purified zinc metal.

Environmental Benefits:

In the past this material has been land filled as a class II non-hazardous waste, since the pellets have had no commercial value. Reclaiming zinc will prevent zinc metal from being land filled and save over 20 cubic yards of land fill annually and the associated cost. By reclaiming the zinc contents the zinc metal can be added back in the system as a raw material and reduce manufacturing of virgin zinc.

Details of Reductions

Additional Information :

Over 25% of the original material cost will be paid to CDC Coatings/Dickson Weatherproof Nail Co. for the waste zinc pellets, generating revenue for CDC Coatings/Dickson Weatherproof Nail Co. in 1993.
