- Millam Tackitt mentioned that truck stops may be a good candidate for
- the safe disposal of hazardous waste such as used coolant.
-
- In the case of coolant, another possibility to consider would be to
- switch to a propylene glycol based coolant (as opposed to the commonly
- used ethylene glycol). Propylene glycol is much less toxic than ethy-
- lene glycol (in fact, it's used in small quantities as a food additive),
- and its antifreeze/antiboil properties are close enough to those of
- ethylene glycol that it should be fine for all but the most extreme of
- weather conditions.
