Does anyone know if all soft plastics are recyclable?  If not then which ones(if any) will be ok if if melt and remold.  I use a lot of GYCB and zoom and would like to use these ones in particular.  

I recycle all of mine, even mix the brands when repouring

I think they are, I recycle mine too.

I reuse all of mine and mix Brands, just some have stabilizer and others dont so some stink real bad and some dont at all.
