New plastic pyrolysis capacity planned in the US

Plants by Braven Environmental and Encina will take in a combined 225,000 metric tons of waste plastic per year.

Two new plastic pyrolysis plants are in the works in the US that could add a new recycling option for plastic trash and increase the supply of some commodity chemicals.

The pyrolysis firm Encina is finishing designs with engineers at Worley for a plant that will take in about 160,000 metric tons (t) of waste plastic per year and yield 90,000 t of BTX, a mixture of benzene, toluene, and xylenes normally produced from oil. The firms say the designs are modular, which will let them add capacity later. This will be Encina’s first plant, and founder David Schwedel says the company has four more in the planning stages globally.

Braven Environmental is planning a plant in central Virginia that will take in 65,000 t of plastic per year and produce 50 million L of a diesel-like hydrocarbon blend, according to Michael Moreno, the company’s chief operating officer. The $32 million plant will also produce syngas, which it will burn to fuel the process. The firm expects to create 52 permanent jobs at the site when it opens in mid-2021.
