Since the pandemic hit the world, conscious people and researchers have become more aware of the climate and urged to take steps to improve its condition. One such group of Indian students from the MVJ College of Engineering have come forward to aid in E-waste management.

They have devised a technique to extract precious metals from the printed circuit boards of non-functioning mobile phones and computers. The method is applicable for gold, silver and copper alike.
Being in prolonged lockdowns has increased the usage of electronic gadgets more than ever and thus generating tons of E-waste. Bangalore is the hub of technology, especially this issue. Thus there was a huge need for efficient E-waste recycling facilities. B Kamala, Akshaya G, Deepthi K V and Chandana M C, employed aqua regia to separate the metal from the circuit board. This is achieved by a process called leaching, through the corrosive nature of the chemical. This is a huge step in the recycling of electronic parts and is economically profitable as well. It is environmentally sustainable and will generate financial opportunities. Their efforts were applauded by their college principal who opened a gateway to making mobile waste more lucrative.

Technology is a useful servant, but a dangerous master, it was rightly said. Electronic devices have grown into an inevitable part of our daily lives.
