1. A feedstock slurry composition comprising recycle plastics, a solid fossil fuel, and water, wherein the recycle plastics have a particle size of not more than 2 mm, and the solid fossil fuel in the feedstock composition has a particle size of less than 2 mm, the solids content in the slurry is at least 62 wt. %, the amount of recycle plastics present in the feedstock stream slurry composition is 0.1 wt. % and up to 25 wt. % based on the weight of all solids, and the water is at least 20 wt. % based on the weight of the feedstock slurry composition, and wherein
the slurry is pumpable as determined by having a viscosity of less than 30,000 cP after mixing to obtain a homogeneous distribution of solids throughout the slurry and using a Brookfield R/S Rheometer equipped with V80-40 vane operating at a shear rate of 1.83/s or a Brookfield viscometer with an LV-2 spindle rotating at a rate of 0.5 measured at ambient conditions
and the slurry has a viscosity of at least 2571 cP as measured at 15 minutes using a Brookfield R/S Rheometer equipped with V80-40 vane operating at a shear rate of 1.83/s.
