Here in Seattle we have a site run by the city that accepts household
hazardous waste, including antifreeze.  Check with your local
government, most do now.

However, it is impossible to do this job yourself without some loss of
antifreeze, but the problem with mechanics is they either dump it in the
sewer themselves or have an expensive self-contained unit that hooks up
to your cooling system and flushes and fills in one process.  You would
be hard pressed to find anyone using one of these machines with Dexcool,
they wouldn't be able to pay for the machine putting in a five year
coolant!  You could call around though.  Your only other choice would be
a VW dealer or German car specialist who fills his with Autobahn
coolant.

For the DIYer, it is best to park the vehicle on unpaved ground that
will absorb the lost coolant and keep it from getting into storm
drains.  It is only toxic to humans and animals if it is consumed in
fairly large quantities, so  soak down the area and don't leave any
puddles when you are done.  It is not harmful to plants, and will be
broken down by natural processes in the soil, but stay away from areas
near wells or storm sewers to avoid contaminating them.
