In Europe, carbon black of vegetable origin is used as a food coloring. The current production of carbon black is 18 billion pounds per year, from which 90% it is used in rubber applications. The average price of carbon black is $700/ton.
For more than 50 years, prices of carbon fiber were extremely high, and the material was viewed strictly as an exotic option for very high-end cars, such as the Chrysler Viper. Prices have steadily dropped since they were above $120 per pound ($1,000 per pound in some cases) 40 years ago.endrik Mainka, a VW project engineer, says that lignin costs about $1.1 per pound versus $1.35 per pound for PAN. Even bigger savings would come with polyethylene as a precursor, because it is less expensive ($0.92 per pound), and has a significantly higher conversion rate than lignin or PAN.
