Why Does Recovered Carbon Black (rCB) Matter?

• Uncoupled from price of oil = stable price over time

• Avoid consumption of oil

• Brings solution to problem of what to do with post-consumer rubber

rCB is one of the pieces in the sustainable polymer industry puzzle

Concern #1: rCB Shows Poor Performance…

• Reinforcement qualities and surface finish quality are insufficient for various rubber applications

• Tinting strength is too low for plastic applications

Solution: Ongoing R&D Investment

• To further develop rCB good polymer-filler interaction knowledge is necessary

• Depending on the polymer type and grade of carbon black being replaced, rCB works well

• rCB further imparts benefits, even in the case of partial substitution

Concern #2: rCB Quality and Consistency is Poor…

• If the input is variable, how can the output be consistent?

• rCB is a “Dirty” carbon black

• Final product is fluffy, oily, smelly and moisture-packed!

Solution: Go Beyond What is Expected in QM

• Feedstock control

• Industry standard post-processing

• Set high internal standards, such as ISO certification

• Exceed product quality requirements, such as attaining product approval for food contact

Concern #3: rCB is Not What it Claims to Be…

11/5/2014 10www.carbon-clean-tech.com

• Can substitute 1:1 ASTM grades!

• Product is really “carbon black”!

• Product can be easily “dropped in” to a mix!

• Oversell and under-deliver!

Solution: rCB is a Complement to Carbon Black

11/5/2014 11www.carbon-clean-tech.com

• Focus on making products that work, not chemistry that resembles carbon black

• Focus on the right applications

• Focus on partnerships with producers of carbon black

• Undersell and over-deliver!

The rCB Industry Needs Your Support

11/5/2014 12www.carbon-clean-tech.com

• rCB as a complement to traditional carbon black is here to stay

• Every big innovation started off as a small idea

• Big opportunity for carbon black industry, and rCBproducers to collaborate on improving the sustainability of the industry

Thank you!
