Cooling system flush question

[John_Mc]

I know I'm overdue for a cooling system flush and I thought I'd do it myself if it's not an overwhelming project. My biggest question before I start is: What does an environmentally conscious person do with all that is flushed out of the system? How much liquid waste is usually produced in the process? Is it just easier to have a facility do it that can handle said waste? Thanks in advance for your input.

I always take stuff like that to my local service station. They can dispose of it properly.
