E-waste is one of the fastest growing waste streams globally, which has been well concerned and documented from regulation to technology since 2005. E-waste is valuable but toxic and imposing the sustainability in environmental quality, resource utilization, and even human health. This presentation will in detail address the global e-waste generation and latest recycling performance. Currently, around 50-54 million tons (Mt) of e-waste was generated, encapsulating 110-140 exascale jole of embodied energy. However, only 12 Mt were recycled in the formal manner with the around 23% recycling rate, contributed a lot by the U.S. and China. Therefore, the appropriate recycling of e-waste can not only protect the environment and maintain resource sustainability, but also save the energy for potential manufacturing to tackle the threat of climate change.
