Problems solved by technology

[0012] While articles and methods related to lignin from tobacco are known in the art, no method has been disclosed so far by which various polymers suitable for use and for use in the manufacture of plastic articles are prepared from tobacco Lignin-containing compositions of any one of compatible dyes or plasticizers or fillers
Since although tobacco has long been grown around the world, the full utilization of tobacco biomass remains to be achieved, there is a long-felt need for methods for preparing from tobacco any of a variety of polymers that can be used in the manufacture of plastic articles. Method for Compatible Dyes or Pigments or Plasticizers or Fillers or Coating Compositions
