Chemical Recycling Plant Takes Shape in Wyoming

Encina (The Woodlands, Texas) has hired Worley (Houston) to provide engineering, procurement, and construction services for a chemical recycling plant it’s building in Gillette, Wyo.
The plant will extract benzene-toluene-xylenes from plastic scrap through catalytic pyrolysis. Encina’s process can use mixed postconsumer plastics as well as ocean plastics as feedstock, Worley says. Encina’s leaders say they plan to focus on plastics No. 3-7: polyvinyl chloride, low-density polyethylene, polypropylene, polystyrene, and others. BTX, also called hydrogenated pyrolysis gas or pygas, is used to make products including pharmaceuticals, clothing, solvents, fuels, and glues. The companies plan to make the technology scalable for later capacity expansion and to build additional facilities in other parts of the world. Encina previously hired Jacobs Engineering Group (Dallas) to provide operations readiness support services. Visit,, or
