Melting plastic without toxic fumes?

[ScienceNostalgia101]

I have a bunch of spare plastic around that I'm considering melting into a plastic sculpture just to prove I can. Is there any way to melt plastic without burning it and/or causing significant amounts of toxic fumes? (By significant I mean enough to harm people either a few metres upwind or several metres downwind; or does that follow from the vapour pressure of molten plastic?)

You know what plastic it is...?

Really depends. Check the type(s) you have. 

Thermoplastics are pretty safe up to a point. Others you should be careful with.

In order to make a plastic sculpture you will probably have to dissolve the plastic in a solvent...you'll definitely need safety goggles and gloves. If you have a lot of the styrofoam then you can dissolve it in acetone...without the risk of toxic fumes.

I checked the bottom of it and it says "7 other." Which, looking it up, yields this. A tad concerning, but it says nothing about the vapour pressure from melting.

Also, not sure if anyone here might recognize the numbers to the left of it, so I uploaded this image of it.

As for gloves and safety goggles, I'll keep that in mind should I choose to go through with this.

Blocked out the barcode, just to be sure...

Where did you get the plastic from? Brand? Maybe you can ask the sellers or producers what kind of plastic it is.

You could just put a bit in a suitable receptacle, heat it and see if it melts... it'll either be non-melting thermosetted plastic or thermoplastic which does melt. That link I posted has the details.
