While working on finalizing my Genomatica interview, here is an interesting story from last week about producing high-grade carbon black from waste tires using a "microwave technology"
According to NJ-based Global Resource, the current global market for high-grade carbon black ranges up to $2,000 per ton. I didn't realize carbon black is so expensive! Around 90% of application is used in rubber the rest in specialty products
The company said up to 300-400 pounds of high value carbon black product/s could be produced from each ton of waste tires when their is commercially scaled. Current global carbon black production is said to be about 18 billion pounds/year (8.1 million metric tons).
The company's microwave technology has also successfully transformed large amounts of scrap tires into diesel fuel, methane, pentane, butane, propane as well as combustible gases, and carbon ash.
Another company worth investigating, I believe.
