Korean researchers have found a way to manufacture graphene on an industrial scale.

Graphene is considered a new miraculous material, 125 times stronger than steal, harder than diamonds, transparent, a great electric conductor and only two-dimensional because of its thickness of only one atom layer. They say graphene will allow microchips with rates of 1000 GHz, conventional silicon-based ones are limited to about 5 GHz for physical reasons.

The science community expects great things of graphene, the EU alone has invested 1 billion euros in a graphene research project.

The only thing I wonder is if graphene is so incredibly robust, how will we get rid of it in terms of waste?

Excellent thinking. I've been wondering the same thing, especially when it gets used more commonly in cars and common objects that can easily get out of a waste stream. I suspect it could become considered a pollutant pretty quickly.

Indeed, they are already suggesting applying a Graphene layer to windows and what not.

I assume Graphene can't be recycled by melting and such established processes Does it even burn?

Graphene is essentially pencil lead (graphite). I don't think there are any concerns about disposing of it.

Graphene is as only good as its imperfections will allow. New methods for Graphene production come out all of the time. I haven't read the article other than the abstract, but one of the most difficult problems to control w graphene materials are imperfections at the edges, which can drastically reduce the theoretical performance of graphene materials.

Wikipedia says graphene is 1 atom thick. I'm guessing it's somehow layered?
