T-Phite, a division of the privately held Sustrend Laboratory, says its process could help solve the problem of over one billion end-of-life tires (ETTs) and help make lithium-ion battery production more sustainable.
The process involves refining carbon black from used tires (ETTs) through pyrolysis, then converting it into battery-grade graphite hard carbon, a key component in lithium-ion battery anodes.
“There are many technologies for recycling tires, but one of them is pyrolysis, which produces three byproducts,” said Bernardita Diaz, CEO and co-founder of T-Phite.
“One is phytolytic oil, another is clothing, and the third is carbon black. This carbon black has no market outlet. And what do we do? We convert these waste tires into graphite material for use in EV batteries,” added Bernardita Diaz.
According to Diaz, approximately 29 million tons of tires are discarded annually worldwide. Ironically, because electric cars require larger batteries, that number is expected to increase.
The World Business Council for Sustainable Development states that hundreds of millions of discarded used tires (ETTs) end up in landfills or simply landfilled every year.
