ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,774,210, issued on Oct. 27, was assigned to Elemental Advanced Materials Inc. (Houston).

"Process for producing graphene, other carbon allotropes and materials" was invented by Ian Bishop (Houston) and Ronald G. Presswood Jr. (Houston).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and systems are described for the synthesis of graphene, synthetic graphite, and other carbon allotropes. Thus, the method describes a method to synthesize carbon nanostructures and synthetic graphite by using unrecyclable materials, such as plastic wastes (i.e., Polypropylene, Styrene, Polyethylene, Poly Vinyl Chloride, PVDF, tires, etc.), Liquid wastes (i.e. tank bot...
