In the near future, one of the key challenges is to develop substitutes or recycling of raw materials that are no longer available, scarce or require a huge amount of fossil energy during production. One example is carbon black, a filler material used in rubber. Carbon black is produced by the incomplete combustion of fossil resources such as crude oil. Every year approximately 1 billion tires are discarded creating around 13.5 million tons of solid waste, containing approximately 4.5 million tons of valuable carbon black. In view of the depleting fossil fuel resources, environmental issues and the enormous quantity of waste tires, cradle-to-cradle loops have to be adopted for the processing of this waste stream. Carbon black recovery from recycling of waste tires constitutes to a market value of 4.5 billion euros approximately and reduces the CO2 emission involved in the conventional carbon black production by 40% approximately.

In this research project, a fundamental insight in the relationships between the process parameters of the new flash recovery process and the quality of the produced carbon black will be gained. The gained knowledge will be used in the selection and design of efficient process steps for the flash recovery process for the production of high quality carbon black. A bench-scale reactor will be developed and used for the investigation of the optimal process conditions and to acquire data and insight in the scaling rules of the process.
Also, one of the intentions of the study is to make the process self-sustainable by using a part of the process gas or process oil as a source of energy to run the process itself and for the tire production. The oil may contain a lot of aromatic components which when upgraded can be used as fuel or as a chemical building block. It will be investigated how the quality of oil can be controlled by optimizing the process conditions or by the introduction of in-situ catalysts.
