Fast pyrolysis of plastic wastes

Preliminary results using an atmospheric-pressure fluidized-bed fast pyrolysis process have been obtained for the fast pyrolysis of commercial grades of polystyrene, poly(vinyl chloride), and polyethylene. On the basis of these tests, polyethylene was selected for detailed study because of the difficulty in regenerating the monomer in good yields and because of its abundance as a waste material ― about 70 % of all plastic waste
