The ability to create graphene from waste negates one of the highest costs within the production process—the cost of the raw graphite products used in the exfoliation processes (which can be $1000-3500 per ton, compared to coal, which is $25 a ton). Compared to CVD processes, it is also a much cheaper and less-complex method.
The process, called graphitization, results in Crystallization of amorphous precursor carbon, which transforms into crystalline graphite. During this high temperature tratment graphite is also purified since most its impurities (binder residues, gases, oxides, sulfur) vaporize.
