Once the theater run is finished, most of the movie prints are destroyed to prevent piracy and the film is recycled. FPC, a Kodak subsidiary, annually recycles more than 3 BILLION feet (about 15 million pounds) of movie film. Much of the ESTAR film base used for print film can be recycled into its original chemical components by a process known as methanolysis: FPC Recycling Program Recycling for Small Volume Users ECO Trailers Kodak Gold Medal from World Environmental Center

The "dope" that was used to treat the canvas skin of the Hindenberg was a mixture of powdered aluminum and cellulose butyrate. It's not cellulose nitrate but it's close enough.The idea was that the aluminum powder in the mix would make the skin reflective enough to keep the sun from heating the gas inside the envelopes. Changes in density during flight could cause the ship to sink or rise in an undesirable manner. It wasn't the hydrogen that caused most of the problems:
A) There wasn't enough oxygen INSIDE the gas envelopes to support a fire... unless there was a leak and it mixed with the oxygen in the air.
B) The gas envelopes were at the top of the ship. The people were at the bottom. People actually used to SMOKE on board. They also had food service and heaters, etc on board. No. Most of the death and destruction was caused by the flammable dope used to treat the skin. Once the hydrogen was gone there OUGHT to have been nothing left to support the fire. But the butyrate skin might as well have been made of dynamite.

There was a programme on television a few years ago about another disaster airship, the R101. If you watch film of that, it certainly doesn't look like hydrogen burning, far too luminous. Of course, all the news film of it was black and white, so you can't tell what colour the flames were.A small area of the skin had survived, and they did some tests on the various layers of coatings on it, no mention of nitrate on this one, but they did find aluminium and iron oxide. If you don't know what that makes, find out how the railways weld their rails together!
