Table 6 : Energy conservation from raw material saving resulting from reclaimed rubber
recycling into new tires.


Raw material Energy consumed for production (GJ/ton) Saving in raw
material (ton/year)*
Energy saved (GJ/year)

SMR 16 [44] 15.5 248
SBR 130 [45] 31.8 4134
Polybutadiene 108 [46] 9.6 1037
Carbon black 126.5 [47,48] 33 4174
Total     9593

*computed from Table 4 as follows:
-saving in SMR=5.8+9.7=15.5 tons
-saving in SBR=27.6+4.2=31.8 tons
-saving in Polybutadiene=4.9+4.7=9.6 tons
-saving in carbon black=21.1+5.3+6.6=33.0 tons
