Resynergi Inc., a 10-year-old Rohnert Park company that has encountered strong local opposition in recent weeks to its plan to start up the latest generation of its unique system for dealing with plastic waste, was told this week it may need more county authorizations.
Sonoma County’s Environmental Health Division sent the company a letter, dated Sept. 16, saying the operation isn’t a recycling center, so it may need to get from the county a solid waste facility permit. The agency and CalRecycle, which regulates solid waste statewide, are talking about what approvals could be needed and are set to make a decision in a week or two, a division spokesperson told the Journal in an email Monday.
“Your facility will use pyrolysis to convert waste plastic into a form that can be re-used,” Director Christine Sosko wrote in the letter obtained by The Press Democrat. “Although your facility might be considered a recycling facility in vernacular language, it is not under state law.”
Resynergi is seeking to turn on its latest research version of its “advanced microwave pyrolysis” system, this one designed to sort, grind up and transform via heat in an oxygen-less slight vacuum up to 5 tons of certain plastics into pyrolysis oil to be trucked off to refiners for making more plastics or fuel. California law treats pyrolysis as “transformation” and not recycling.
