Too funny.  I have joked for years that during a war the US should drop garbage on enemy forces as a way to clear our landfills.  Load all of the trash in to planes and just drop it on the enemy battlefields.  I mean everything.  Scrapped cars, appliances, tires, residential waste, everything.

With regards to the bowling balls, it is surprising that the ball manufacturers do not have a way to pulverize bowling balls in to dust.  Even if they are not recyclable, at the very least it would make their footprint a little more manageable for disposal.  It would be interesting if the companies could come up with a way to do that, and then offer a $5-$10 rebate to bowlers who trade their old ball in for a new one from the same brand.  Then the old ones get returned and pulverized.

I saw a story a month or two ago that addressed this issue (bowling ball disposal/recycling) directly and basically they aren't recyclable due to the differing types of materials used in construction (cover, core, filler, etc.).

Also, destruction/reclamation was net energy-positive, meaning the calculations of cost versus whatever metrics are used to score how much the balls "cost" you to dispose of in a landfill was tilted clearly toward outright disposal, not reuse.

I have a friend that was a PSO for years and just on a lark, decided to recover the core out of an old ball to display it and the amount of time, energy (and electricity, I'm sure) that it took to get the core out of the ball and into a displayable condition was significant. And he still didn't have a completely clean core at the end.
