Using PCC in IT products presents significant challenges due to the unique structural, performance, and cosmetic requirements associated with these applications. To overcome the continuing challenges of using recycled content in the design and manufacture of smart connected devices, especially notebooks, tablets, and smartphones, Lenovo's engineers work closely with our suppliers to develop and qualify new grades of plastic resins previously unavailable to the IT industry. These materials receive environmental and performance qualifications before their approval and use in our product applications.

For CL PCC, Lenovo's research and development teams work with material suppliers and a third-party certification authority to build our CL PCC supplier and material process, including the "Approved Recycling Standard", the "Quality Assurance Operation Requirements", and the "Recovery Ratio" to validate their sources of waste and control processes using a hierarchical waste product traceability scheme.

To learn more about Lenovo's use of recycled content materials, please our most recent ESG Report.

Please note: Lenovo calculates and reports net recycled plastics content based only on the actual weight of the post-consumer or post-industrial recycled content in the plastic resin blend, not the overall weight of the blend. That means that for every 100 lbs of a plastic resin blend containing 30% post-consumer content, the net usage Lenovo reports is only 30 lbs of post-consumer content, not the overall weight of the material
