Plastic Caps

my daughter's school students are asked to collect plastic bottle caps. He said that for each PAC raised a child can receive one minute of dialysis. It seems strange, but I've heard of crazier things. If this is not true, where can I find information to take to school to stop the reader "plastic cap"?

No, this is not true, the school is wasting their time. See my source below

It would be better for the school to do a little promotion of organ donation.

I used to be on dialysis.

yes
