[GreenYes] Used Tire Hiearchy

["Jeff Morris" <jeff.morris@zerowaste.com>]

According to a just released study by the German 
environmental agency, using scrap tires in road 
surfaces (rubber modified asphalt or RMA) ranks 
above burning tires in power stations. I didn't 
specifically single out RMA in the used tire 
hierarchy because I hadn't found a life cycle 
analysis on that use. I haven't seen the German 
study yet, but it appears that it will be an 
important addition to our knowledge on scrap tire 
management. 

The civil engineering applications which I ranked 
equal to energy recovery were uses such as shredding 
for use in road beds under the road surface or other 
such applications where the shreds substitute for an 
aggregate. That designation was not meant to cover 
use in road surfaces.
