Braven Environmental has idled its Zebulon, North Carolina pyrolysis plant after roughly five years of operation marked by dozens of hazardous waste violations, and the state Department of Environmental Quality now plans to assess the site for potential chemical contamination.

The company, which claimed it could process around 90 percent of plastics via pyrolysis, told regulators in May 2025 that operations had stopped. Michael Bloss, vice president of engineering and construction, wrote to DEQ: "We have idled the plant for the foreseeable future and are not pursuing any activity that is not an immediate Environmental, Health, or Safety or Compliance Item."

Braven still holds its regulatory permits and has not asked for them to be rescinded, a DEQ spokesperson said. Agency staff who visited the site recently noted the facility does not appear to be operating.

What does the record show?

EPA records classify Braven as a "large quantity generator" of hazardous waste. Over its operating life, the plant produced dozens of tons of benzene, a known carcinogen, alongside waste containing arsenic and hexavalent chromium. From 2020 to 2025, the facility operated at the Triangle East Business Park in Zebulon, 24 miles east of Raleigh.

State inspection records document a pattern of mismanagement:

• In April 2023, DEQ issued an "immediate action notice of violations" alleging Braven disposed of oils it could not sell as hazardous waste.
• Inspectors found the company shipped hazardous waste to an unpermitted warehouse a mile and a half away, without shipping manifests or the name of the trucking company.
• Company contractor sampling found arsenic and hexavalent chromium above state standards in several areas, prompting DEQ to order retesting over lab quality-control issues.
• In May 2024, DEQ specialist Thad Valentine found roughly 40 storage tanks of petroleum residue outdoors, at least one crushed by heavy equipment, and open drums without required containment.
• Raleigh denied Braven's 2023 stormwater permit request after samples confirmed benzene levels exceeding regulatory limits.

"They just had an incident last week where some landscape workers at the business next door became sick while working next to Braven, and an ambulance had to come," Valentine wrote in a 2024 email. "EPA called this morning with questions." An EPA special agent visited the plant in February 2025 after observing unexplained water draining from a stormwater pipe. The agency declined to comment on potential enforcement.

How does the closure fit the wider pyrolysis sector?

Fewer than a dozen U.S. facilities claim to break plastics down for reuse through pyrolysis. Braven's shutdown follows Freeport Eco Systems' closure of its Ohio pyrolysis plant weeks earlier. Waste Energy scrapped a planned Fayetteville, North Carolina plant in March 2025 amid public opposition and relocated to Midland, Texas, where it has yet to begin production.

The American Chemistry Council, which once showcased Braven — including organizing a lawmaker trip during New York's packaging reduction debate — defended the sector. "Advanced recycling is an emerging manufacturing sector, and in any competitive market, some new businesses will scale, some will pivot, and some will close," spokesperson Matthew Kastner said. "One small facility does not define an entire industry."

Critics read the record differently. "This should take the argument away that chemical recycling is the solution," said Judith Enck, former EPA regional administrator and president of Beyond Plastics, whose staff confirmed the plant's dormancy in late June.

What happens next?

The pending DEQ site contamination assessment will determine whether the Zebulon property requires remediation, and the fate of Braven's still-active hazardous waste permits now sits with state regulators. Any federal enforcement action, which EPA will not confirm, would run on a separate track.
