Is there a recycling program that accepts unrepairable inner tubes? The local bike shop, not the wealthiest operation, has a pile of dead inner tubes growing on the floor. I'd love to discover something where used inner tubes are repurposed, melted down, made into something else. Similar to how e-waste is harvested and repurposed.

We have need for only so many rubber bands and so many bungees.

They recycle inner tubes into usable products, and will give you credit towards their products for recycling.
