Good Idea: Recycling and Saving Costs

The AP wires are carrying a cool story that talks about recycling, saving municipal costs, protecting trees, and is good on your joints.  Wow, what can do all that?  Two words: rubber sidewalks.  Yeah, sounds kinda boring, but if you read through the story, the sidewalks are made out of recycled car tires, last seven years without cracking from exposure, accomodate tree roots longer without breaking, and are easier on joints from walking and falling.  Converting the old tires into the sidewalk squares is more expensive, but over time, the savings to municipal services in replacing sidewalks at the current rate of every three years, spending less on tree maintenance, and saving healthcare costs on degenerative joint pain and emergency care could add up to a lot.
