Graphene is free when you flash heat unsorted recycled plastic and sell or use the Hydrogen. Graphene can be produced from CO2. CO2 is overly-abundant and present in emissions that need to be filtered anyway. What types of graphene and other forms of carbon do not conduct electricity, are biodegradable , and would be usable as a graphene PCB for semiconductors and superconductors? Graphene Oxide (low cost of production), Graphane (hydrogen; high cost of production), Diamond (lowering cost of production, also useful for NV QC nitrogen-vacancy quantum computing; probably in part due to the resistivity of the molecular lattice), How could graphene oxide PCBs be made fire-proof? Non-Conductive Flame Retardants: phosphorous, nitrogen (melamine,), intumescent systems, inorganic fillers Is there a bio-based flame-retardant organic filler for [Graphene Oxide] PCBs?
