Plastic bottles in Connecticut face 25 percent recycled-content mandates by 2027, under a bill passed unanimously by state lawmakers as their session ended June 7.
The plan, which was part of much broader waste management legislation, now goes to Democratic Gov. Ned Lamont's desk.
The bill covers containers in the state's bottle bill, including PET bottles for soda, water and other beverages.
Earlier this year, Lamont came out in support of requiring recycled content in plastic beverage containers, saying in a statement he was focusing on plastics because of low recycling rates and low use of recycled content compared with other packaging materials.
The legislation that heads to Lamont's desk to be signed or vetoed does not include extended producer responsibility for packaging, which Lamont had also endorsed in his January statement.
Packaging EPR provisions were removed from the bill as it made its way through the legislature.
The legislation would increase the recycled-content mandate for plastic bottles to 30 percent by 2032.
The head of the state House's environment committee told the CT Examiner news website that the 30 percent mandate was loosened from earlier versions to ensure adequate supply of recycled feedstock.
Lamont's original proposal called for 50 percent recycled content in the plastic bottles by 2033, with the governor saying he wanted to mirror California's requirement.
The broader waste management bill tackled more controversial topics, including how the state would replace a waste burning energy plant that shut down last year.
