According to The Global E-waste Monitor 2024, published by the International Telecommunication Union (ITU) and the United Nations Institute for Training and Research (UNITAR), only 22.3% of electronic waste generated globally in 2022 was documented as formally collected and recycled.

The report establishes that approximately 62 million metric tonnes of electronic waste were generated worldwide during 2022. Of this total, approximately 13.8 million metric tonnes entered documented formal collection and recycling systems.

The remaining 77.7% was not recorded as formally collected and recycled. This does not necessarily mean all remaining equipment entered landfills; some may have been stored, traded, reused, or processed through undocumented or informal channels.

The relatively low documented recycling rate highlights substantial challenges associated with electronic equipment disposal, resource recovery, environmental pollution, and global waste-management infrastructure.

Cisco's circular economy initiatives directly address these challenges through product lifecycle extension, equipment takeback, remanufacturing, and responsible recycling programs.

Options A, C, and D do not match the documented global recycling percentage for 2022. In particular, 62 million tonnes represents the total quantity of e-waste generated, not the percentage recycled.

The 22.3% statistic illustrates why structured recovery programs are important for minimizing environmental impacts and improving the conservation of valuable materials.
