These are cost estimates for automotive mercury recycling (per lb. of mercury removed) for various switch collection program options: mailing system ($245 to $300), Conditionally Exempt Small Quantity Generators' CESQG programs ($450 to $750), non-government assisted ($550 to $850) and End-of-Pipe treatment ($10,000 to $20,000). 

When using a mailing system to get the switches to the recycling facilities, the base cost for recycling ranges from $20 to $70/lb for removing mercury. The cost of $0.38/ball-bearing replacement switch adds $170/lb of mercury removed from automobiles. Additional labour costs for skilled mechanics adds $450/lb. A total cost estimate for this program ranges from $640-$700/lb of mercury removed.

Mercury switch collection programs for end-of-life vehicles are cost effective, but mercury capture rates are lower. Replacement programs have a 100% capture rate and prevent losses due to switch corrosion and disposal prior to end-of-life. Replacement programs are well suited to fleets, mandatory vehicle inspection programs, used car dealers, and service centres. The costs can be equivalent to end-of-life collections if labour is supplied as an in-kind service. The use of both systems ensures higher capture rates at costs that are well below the end-of-pipe treatment. 

In conclusion, the replacement programs and mailer systems will enhance capture rates of end-of-life collection programs. In fact, the replacement programs for on-the-road vehicles are pro-active, cost effective, and educational for the public. The mailer system lowers costs for both end-of-life and replacement program. A combined approach of replacement for on-the-road vehicles and collection programs for end-of-life vehicles is recommended.
