As the world faces pressing environmental challenges, the demand for sustainable materials and practices continues to grow. Recovered or Recycled Carbon Black (rCB) is carbon black recovered/reclaimed from scrap or waste-life tyres. In general, rCB can be recovered from any kind of rubber waste. The majority of rCB is obtained by the pyrolysis process of end-of-life tyres, which are widely available and offer a consistent waste stream worldwide. This unprocessed or raw material from the pyrolysis process is of low value and has limited applications, such as fuel in cement kilns. This raw Carbon Char or recovered carbon black needs to be further refined as per the requirements of the markets and end application. The name “recovered Carbon Black” (rCB) should be applied to the raw Carbon Black which is free from metals and fibers and was micronized. This micronized carbon black can be further pelletized to give a significantly high-priced value-added product. There are pyrolysis installations capable of providing quality carbon black directly from the production line, but there will still be a need for micronization and pelletization. This recycled carbon black is used in conjunction with Virgin Carbon Black in tyre applications and is found to give an excellent reinforcing effect to the tires. In this article, we explore the potential of recycled carbon black (rCB) as an eco-friendly alternative to traditional carbon black derived from fossil fuels.
