Actually, very little of our plastics get recycled. Just read a report yesterday finding that less than 10% of all plastics marked recyclable are actually recycled. Most is hauled off to landfills with the rest of the trash. I know where I live we have recycle truck but it is a show only. It goes to the landfills. Just a feel good gesture to fool the folks. I take my aluminum recyclable to a recycle center myself where they pay for it. That way I know it isn't hauled as trash.
We had recycling dumpsters at my work next to the garbage dumpster, they dumped one than the other in the same truck. What a surprise that was.
While recycling plastic waste, such as bottles and cups, is a common practice, recycling plastic shotshell wads can be more challenging for a few reasons such as contamination, Material composition.
I worked at a few mold shops that also had molding machines. The runners/gates from the parts were ground up and added to the virgin material. I believe it was around 10% reground material. The reground material does not have the properties of virgin material.
about 15 years ago a fellow out in the desert began recycling wads AND HULLS. the epa shut him down. he use to make gun racks and benches for gun clubs with them. employee contamination and cleaning overheads killed the idea. sad. it was a good idea. you would order bags to get on his shipping routes and just call him....and trucks would come and get them. he even supplied the free bags.
