Senate Bill 702 mandates that battery stewardship organizations in Wisconsin must establish and manage programs for the collection and recycling of covered batteries, which include both portable and medium format batteries. The bill defines a battery stewardship organization as a non-state entity designated by battery manufacturers to implement a stewardship plan approved by the Department of Natural Resources (DNR). Starting January 1, 2027, producers are prohibited from selling covered batteries or products containing them unless they are part of an approved stewardship plan, which includes requirements for annual reporting, consumer education, and proper labeling of batteries. The bill also outlines specific definitions for various types of batteries and establishes penalties for non-compliance, including civil forfeitures for intentional violations.

Additionally, the bill stipulates that beginning January 1, 2028, it will be illegal to dispose of covered batteries in landfills or through incineration, with disposal only permitted at designated collection sites. The DNR is tasked with approving stewardship plans, maintaining a public website with relevant information, and ensuring that battery stewardship organizations cover the costs of their programs. The bill emphasizes the importance of public awareness and education regarding battery recycling and establishes a framework for monitoring and reporting the effectiveness of these stewardship programs.
