Bit crap that it doesnt actually go into any detail at all on the recycling of the carbon. There is 1 line where it states that the carbon come from the production of the i cars.
Also from looking at the material I would say it's closer to the Lamborghini forged carbon than a regular weaved carbon.
The forged carbon is also recycled then it goes through a very similar process to regular prepreg carbon where the fibre is impregnated with epoxy resin. By manufacturing the carbon with epoxy already in it you save weight by reducing excess resin. Then you have a prepreg sheet of recycled carbon.
Looking at the arches in the close up picture there isnt a weave it looks much more like chopstrand mat, which to me says the excess carbon from i3 and i8 production had been chopped up and then turned into a prepreg sheet.
