Abstract: Systems and methods are provided for conversion of polymers (such as plastic waste) to olefins. The systems and methods can include a recycle loop so that a portion of the pyrolysis effluent can be combined with solid plastic feedstock. The input flow to the pyrolysis reactor can correspond to a slurry of plastic particles in recycled effluent or a solution of plastic in recycled effluent.
