AL SB264

Adds "mass balance attribution" definition as an optional chain of custody accounting method for manufacturers to track input and output of materials, with methodology defined by optional third-party certification systems approved by the Alabama Department of Environmental Management.

Enables third-party certification systems to allow manufacturers chemically processing recovered materials (including pre-consumer or post-consumer plastics) to attribute chemical recycling feedstocks to chemical recycling products and have them considered recycled content.

Designates recovered materials processing facilities as manufacturing facilities (rather than solid waste management facilities) under the Solid Wastes and Recyclable Materials Management Act.

Requires recovered materials processing facilities to provide notification to the department according to rules adopted by the department no later than January 1, 2025.

Takes effect October 1, 2024.
