Establishes extended producer responsibility for gas cylinders

Removed the amendment to the State Finance Law, restricting the bill's changes to the Environmental Conservation Law.

Updated the definition of 'gas cylinder' to remove the specific list of flammable materials (propane, butane) and replace it with a broader reference to 'flammable materials,' while also removing the exclusion for cylinders containing hydrogen.

Reorganized the 'recycling' definition to combine energy recovery exclusions and chemical conversion processes into a single clause, and added a specific exclusion for landfill disposal of component materials.

Added a new definition for 'recycling rate' to establish a metric for measuring the percentage of discarded cylinders managed through recycling or reuse.
