Relating to advanced recycling.

HB 4011 creates a certification framework for verifying that recycled materials used in manufacturing actually contribute to the final product, through third-party certification of "mass balance attribution." This directly affects manufacturers who want to use recycled feedstock (like plastic waste) in new products, as it standardizes how recycled content is measured and verified. The bill amends West Virginia's solid waste laws to clarify that advanced recycling facilities (which convert waste plastics into raw materials) are not considered waste disposal sites, supporting their role in recycling. By streamlining certification, the bill aims to reduce barriers for businesses adopting recycled materials in production.
