So where do you dispose of the hazardous waste?

Sealed lead acid batteries.
Use up alkaline batteries.
Dead LI batteries.
NiCd batteries.
etc.

They don't go in the trash but they are piling up in the corner.

Any stores take them?

The only spot I know about around my area is 1/2 hour drive in nasty
traffic ... and they want us to dispose this stuff of properly. I'll
bet that most people put them in the trash but I am not willing to go
there (either place).

Radio Shack, I think Best Buy also.

I just put 'em in the trash. My philosophy is that anything that fits
into an opaque garbage bag can be put out with the regular household
garbage.

I got some hazardous insect killer I wanted to dispose of. There is one
place I can take it, across town, once a year. Like hell I will.

I ran into the same issue with old gasoline.

miss a day of work and carry it by hand to the city dump which is only
open like 3 hours one every two weeks?

**** that.

I poured it out in the alley and on the patio.

my last jug of vacuum pump oil went into the trash. It's just mineral oil,
no big deal unless you call it used vacuum pump oil and people assume it
was used in to manufacture semiconductors or something else with exotic
toxic nasty stuff.

Pump oil is usually dioctyl pthalate, AFAIK, which is a popular
plasticizer due to its lowish toxicity and very low vapour pressure
(which is also what makes it good pump oil).

there's many types. I use the cheap stuff, which is just mineral oil,
under more exciting names like "paraffinic petroleum distillates".

the MSDS sheet for the stuff are clearly some sort of wikipedia copy
and paste from somewhere else type deal, with a logo and phone number at
the top.

The part I've not figured out is why or how does silicone diffusion pump
oil go bad, and why does it have an expiration date on the bottle.

I even asked people at a national lab with diffusion pumps all over the
place and nobody really seemed to know.

Probably because some silicones are used in medical devices, and
the FDA gets very crazy when they cannot determine expiration
dates. Or calibration dates.

It also means some customers will reorder more often. I recall,
however, we loaded our diffusion pump and NEVER thought
of replacement of the silicone oil unless it got too dirty to pump.

The Dow 704 I have actually says on the bottle "NOT FOR HUMAN INJECTION!".
I even wrote to Dow asking if people shoot up vacuum pump oil, and if so,
why. I never heard back, but was apparently enough of a problem to put
this on the labels in 2003.

How did you determine the diffusion pump was dirty? I'm still not clear on
how you even drain the oil out of the one I have, other than the turn the
entire thing upside down, and hope everything drips out. Do you then wash
it out? Silicone oils are pretty disgusting, and I'm happy the stuff
hasn't crawled out of the pump and all over the place.

I didn't bother on purpose. Get it?

You seem to have some disability so I will not go into that.

The point was to get global input from the people reading this post
where they were located so ALL others who might read this post will get
ideas about how to do recycling in their area. Now do you get it?
