I would like to know researchers view on this area,
What are the possible sources?
Plz, let me know references.
We have developed an integrated technology for producing nanopowders of metals from waste. Solid waste (spent magnets, scrap electronic industry, exhaust gas neutralization catalysts) is dissolved in acids. Ion flotation is then used to selectively extract ions. Then we reduction the ions into nanoparticles in the direct micelles of the surfactant. Nanopowders of bismuth, gold, platinum, copper, cobalt ferrites, and nickel ferrites were obtained using this technology.
See articles on my profile.
I don't work on the nanomaterials but I know few people working on it, and they are able to make graphene and CNT from some type of waste materials (like agriculture and other organic waste) which contain C.

Dear Bhaskar Bhatt
Please check my paper:

indeed graphene can be made from waste materials . See for example : Ruan et al. ACS Nano, 2011, 5 (9), pp 7601–7607 DOI: 10.1021/nn202625c
