This bill mandates that, starting January 1, 2030, all new washing machines sold for residential, commercial, or State use in New Jersey must include a microfiber filtration system designed to capture microfibers and microplastics. The filtration system must have a mesh size of no greater than 100 micrometers. Additionally, these washing machines must display a conspicuous label informing consumers about the filter, which reads: "NOTICE: THIS WASHING MACHINE CONTAINS A FILTER TO CAPTURE MICROFIBERS. CHECK THE FILTER REGULARLY AND DISPOSE OF CAPTURED LINT IN A WASTE BIN."

To enforce compliance, the bill establishes civil penalties for violations, with fines of up to $10,000 for a first offense and up to $30,000 for subsequent violations, to be collected by the Department of Environmental Protection (DEP) through a summary proceeding under the Penalty Enforcement Law of 1999. Furthermore, the DEP is tasked with adopting necessary regulations to implement the bill's provisions within one year of its effective date.
