Microwave-induced pyrolysis: A promising solution for recycling electric cables

The demand for electronics has led to a significant increase in e-waste. In 2022, approximately 62 million tons of e-waste were generated, marking an 82% increase from 2010. Projections indicate that this figure could rise to 82 million tons by 2030.

E-waste contains valuable materials such as metals, semiconductors, and rare elements that can be reused. However, in 2022, only 22.3% of e-waste was properly collected and recycled, while the remaining materials, estimated to be worth almost $62 billion, were discarded in landfills.

Although efforts to improve e-waste recycling continue, the process remains labor-intensive, and a significant portion of e-waste is exported to developing countries, where cheap labor supports informal recycling practices involving hazardous chemicals.
