Mechanical recycling: Dow becomes first to achieve traceability and recycled content certification for PE compounds


Certification granted by AENOR, a top ten global body for management systems and product certification.

Dow announced its post-consumer recycled-rich resins, REVOLOOP™, are the first polyethylene (PE) compounds to be certified in accordance with the Standard UNE-EN 15343 for plastics recycling traceability and recycled content. The certification has been granted by AENOR, a global company and the Spanish leader in conformity assessment and extends to all three grades offered by Dow in Europe.

Stop the waste, close the loop
REVOLOOP™ grades are part of Dow’s plastics circularity portfolio and incorporate a high percentage of post-consumer recycled (PCR) material. The single-pellet solution enables a simpler PCR process integration, meeting the needs of converters, brand owners and sustainable packaging designers, and can be used in a broad range of applications. Providing access to quality, consistent waste streams, and increasing reliability in the waste value chain, the REVOLOOP™ family of PCR-rich resins expand Dow’s sustainable offerings portfolio to help advance a closed loop system for plastic waste.

“REVOLOOP™ represents a tangible step towards realizing our vision for a circular plastics economy,” said Peter Sandkuehler, European Sustainability Director for P&SP. “It exemplifies Dow’s efforts around the world to enable mechanical recycling and the incorporation of PCR in a variety of technologically demanding applications. Such progress will bring all the players in the value chain further in their sustainability journey.”

Certified sustainable production
The UNE-EN 15343 is the European Standard that specifies the procedures needed for the traceability of recycled plastics and covers two schemes: the traceability and characterization in the plastic recycling process, and the minimum content of post-consumer recycled plastic used in the processing of a plastic product.

This certification was awarded following a full independent, external audit to ensure that the control of incoming plastics waste, the traceability in the production processes of recycled material complies with the requirements set out in UNE-EN 15343 standard. Therefore, AENOR has verified that the manufacture of Dow’s polyethylene compounds contains up to70% of post-consumer recycled products, which have either fulfilled their intended purpose or can no longer be used for the purpose for which they were conceived.

In order to grant this certification, AENOR first checks the origin of the post-consumer recycled material. The process continues with the analysis of the main processes applied by the organization in the manufacture of the products in the scope of the certification, with special emphasis on the control of the equipment that fixes the dosages during the manufacturing process. Finally, the calculation protocol applied by the organization to determine the percentage of recycled material incorporated into the products is audited, verifying that it provides the necessary confidence, by means of periodic controls, so that the products marketed over time effectively contain the minimum declared.

“This certification demonstrates Dow’s commitment to offering products that minimize the use of the planet’s resources, offering the plastics transformation chain the possibility of including materials with recycled content endorsed by AENOR certification, and showing its commitment to the environmental values shared by society as a whole. Dow is now the first company to obtain this certification for polyethylene compounds”, says Yolanda Villaseñor, Director of ProductCertification at AENOR.
