isnt rubber mulch pollution...that rubber will never disintegrate
Sure...it will never disintegrate.
But as long as it's properly maintained (and contained) in the playground or landscape, it can't be called "pollution" by definition because it doesn't
leach, into the soil, and it's attractive to the eye even after long periods of time.
If you want to get into the real "meat" of this debate...you could argue that applying traditional wood mulch or whatever, year in and year out, in effect causes more
"pollution" than rubber mulch simply because of all the extra hauling and dumping needed EVERY YEAR; not to mention the environmental impact of accessing materials for the wood mulch & the fuel needed to process wood mulch every year in bags, and to bring it to bulk pick-up sites EVERY YEAR..
vs.
the cost of recovering tires, safely processing them into mulch, and delivering those products, bagged and bulk, to pick-up points, in theory, only..
ONE TIME.
