- Researchers from IISER Pune have developed a novel hybrid aerogel capable of easily extracting gold from electronic waste.
- It could potentially be useful in addressing e-waste management besides lowering the burden on the hazardous mining practices.
- In daylight, the hybrid aerogel could extract 1689 mg/gram of e-waste and 2349 mg / gram under blue light.
- India’s electronic waste generation has been rising exponentially in recent years, even though its global share is just 6.4 per cent.
- Between 2020 and 2022, the e-waste generation grew by 131 per cent.
- The global e-waste monitor 2020 report has projected an increase of e-waste from 9.2 million tons to 74.7 million tonnes by the end of this decade in India.
