1. A continuous process for transporting a waste plastic feedstock to a refinery processing unit, comprising:
processing a first solution comprising (i) about 1 wt. % to about 40 wt. %, based on the total weight of the first solution, of one or more first waste plastic feedstocks and (ii) a recycled inert carrier fluid received from a refinery processing unit in the presence of a catalyst under catalytic cracking conditions, thereby producing a processed first solution;
separating the recycled inert carrier fluid from the processed first solution, thereby producing a separated recycled inert carrier fluid; and
forming a second solution comprising (i) about 1 to about 40 wt. %, based on the total weight of the second solution, of one or more second waste plastic feedstocks and (ii) the separated recycled inert carrier fluid.
