Process

Delta-Energy Process for Recovered CB - CO2 Savings

Delta-Energy Quality

• Delta-Energy Group achieved ISO 9001:2015 certification

• At the end of 2019 will be capable of processing rubber from ~3 Million tires annually

D-E Black® Product

• D-E Black® is recovered with less impact to surface area and structure

• Since the Carbon Black is recovered from used tires, it is a blend of sizes in the semi-reinforcing region of the usage chart

• Many applications in case compounds are possible

Application of D-E Black® in Consumer Sidewall

D-E shows excellent retention of strength characteristics

D-E is slightly less reinforcing than N550 which can be easily addressed with an improved CB balance

D-E has excellent dynamic ozone retention, above 25% replacement of N550

Conclusions D-E Black®

The D-E Black® is a viable partial substitute for virgin carbon black in the compounds that use semi-reinforcing carbon black grades

The material has minimal impact to properties and performance and can be applied to have equivalent tire performance with no or little tuning required

Based on the properties of the black and the compounds, Bridgestone plans to continue to expand the use of D-E Black®

Conclusions Bridgestone

Bridgestone is committed to help ensure a healthy environment for current and future generations

Around the world, the Bridgestone Group is working to conserve natural resources through operational improvements and product design

Bridgestone is working to advance an environmentally sustainable society and support a circular economy
