Plywood (& customwood - MDF) has a urea/formaldehyde glue holding it together.
When you burn it it releases it into the air, its really bad for you.

Methanol, if its drunken, breaks down into the body into formaldehyde & that does something to the back of your eyes & makes you go blind.
You might remember hearing about bad 'homebrew' alcohol or people (most likely in Russia) drinking methanol, or even adding it to their alcohol & dieing or going blind, thats how it happens.

I will try the hotpot method, melting the plastic off in a pot on a fire & see what happens, I will report back.

A while ago I put some plastic coated wire into a tin can & added Dichloromethane (DCM - paintstripper) to it.
The plastic swelled up to 3 or 4 times its size over a couple of days & turned into a pasta like consistency while still on the wire.
I then let it evaporate off & it went back to what it was like beforehand.
Very very interesting.
DCM is not really flammable, its got a boiling point of 40Deg C, pretty low actually.

I could slip the expanded plastic off the copper wire real easily.
I think if one got a barrel of loose plastic coated wire & added DCM & then let it absorb & then did some other action, like centrifugal force or something.
The plastic would slide off the wire & leave the brightest coloured copper you ever saw.



Problem now would be loosing the DCM to the atmosphere when removing the copper wire.
The DCM in the plastic could be easily recovered by just heating the plastic & condensing it again, maybe back into a second drum of covered wire. Thanks to its low boiling point.

Expressing the mix might work, a properly made drum with a potato masher like part in it that would push the wire to the bottom of the drum, while the DCM/plastic gets pushed thru the masher up above it.
Like a coffee plunger pot.

I'm gonna work on this idea, as I'm making it up in my head as I type.....
