The emergence of the Circular Economy necessitates tire recycling and pyrolysis has emerged as a leading technology. Pyrolysis of waste tires creates two useable streams: tire pyrolysis oil (TPO) and reclaimed carbon (rC). While the use of TPO in various chemical processes is fairly straightforward, including as a carbon black feedstock, the use of rC is more complicated. We examine the rubber properties achievable with various available grades of rC having different ash content, silica content, and other properties. We show that, as-produced, these materials cannot satisfy the demanding performance targets of tire technology. We then discuss some upgraded materials.

What the audience will learn

• The rC production process is very different from the carbon black process.
• rC imparts deficiencies in rigidity and fatigue.
• rC alone cannot be used at high substitution levels for carbon black in most applications
• rC can be upgraded to match dispersion and tensile properties for semi-reinforcing applications at 30% loading.
• An alternate upgrade route can match most properties for reinforcing applications at 20% loading.

A major target for for increasing circularity in the tyre industry is to find a technology for re-compounding ELT tyres. Sustainability of new tyre production and retreading can be enhanced not only through circular-attributed polymers from R-oil, but also by introducing recycled rubber from both devulcanization and micronization. eSBR with microdispersed ELT powder is combined with devulcanized and fresh rubber to maximise the recycled component.

Tire sensors can generate huge volumes of raw data. The challenge for a systems designer is whether to process that data locally, and send intelligence-rich data up to the cloud, or to send all the data to the cloud for subsequent processing. The latter choice requires substantial bandwidth, which can be costly, and limit performance in regions where connectivity is low. Processing data locally is the preferred option, but that needs specific solutions. PolyN is working with top-name tire makers to build systems that can extract intelligence from the raw data before sending it to the cloud.

There is a growing demand of advanced optimization software solutions for the commercial transport industry. In response to that, Dynamon developed solutions such as Zero, to optimize the transition from ICE to EVs, and Tire Analytics, which is intended to reduce fleets total cost of ownership, identifying the costs and environmental impact associated with the different tire choices for each specific service. Angus will explain how to generate extraordinary benefits to fleets and allow tire companies to use valuable insights for tire development.
