What are the consequences of melting plastics from ocean garbage patches?

[ANarwhal]

What would happen if I trawled one of the oceans garbage patches (say the great pacific or atlantic garbage patches) and put everything I trawled into a furnace with an inert gas hot enough to melt the majority of plastics I picked up, what would be the outcome?

I am looking to know more about why certain types of plastics may not combine with others into a big mold.

You would be making a big mess which you wouldn't be able to recycle.

Would the plastics still form 1 solid?

Hard to say. Most likely yes, but not a homogeneous one. As SteamKing wrote, all you will get would be something messy.
