Hi, valid point.
Yes, pyrolysis process is simple enough in theory.
The company has done a lot of experiments, and done trial and errors with several permutations and combinations to arrive at the optimum reactor settings (which includes differential temperatures in different zones of the rotary kiln, differential horizontal velocity as the tyre passes through the reactor and gets decomposed, and the rotation speed of the kiln) so as to give the highest quality output depending on the quality and chemical composition of the waste tyres. Which differs by geography (tyres from USA for eg, have lesser silica content than European tyres), quality for CV, PV and other tyres are different etc.
The company started with lab scale input and then progressed to commercial scale at lower capacities starting from 1kg and moving higher till they reached 100 tpd capacity. At each stage, the plant and machinery underwent several modifications which was made possible because their own group company was manufacturing it.
One can search on Youtube for batch pyrolysis plants (eg. https://www.youtube.com/watch?v=pvbfOQHlP50) to realise how energy intensive and inefficient such process is. So there is no comparison of continuous process with batch process.
Within continuous process, the edge of the company is the above efforts they have taken and their own in house manufactured machines which have been designed to produce high quality rCB (recovered carbon black) most economically.
