Laying old car tire crumbs underneath a golf green doesn't sound like a great idea, until you speak to University of Wisconsin-Madison researchers. They've been able to demonstrate how "ground-up tires placed beneath golf course greens absorb excess chemicals from fertilizers and help prevent groundwater contamination". Check out the article here.
But I am a little concerned about the rubber leaching, this study suggests there is reason to worry - "components of crumb rubber produced from tires, volatilize into the vapor phase and are leached into water in contact with the crumbs".
We'll see where this goes in the future, nevertheless I am intrigued by its potential recycling/re-use capacity and pollution prevention characteristics.
