Hmmm, last I checked concentrated sulfuric acid is not commonly available to or advised to be used by the public . . . so forget about the common man recycling this stuff, just another development of "big corporate" to keep this product and the system surrounding it all within their clutches. On the other hand, my son and I just filed a patent for a low melt temp polymer system that is flexible, recyclable merely with low heat, biodegradeable (without acids), repurposeable, NON TOXIC, and all processes can be done at home safely by the public, no corporate involvement necessary.
