[2026] PTE Academic Writing - Summarize written text

The rapid turnover of consumer electronics has created a massive global challenge known as electronic waste, or e-waste, which is now the fastest-growing waste stream in the world. Traditional disposal methods often result in toxic chemicals leaching into the soil, but a new approach called 'urban mining' views this waste as a valuable source of precious metals. By recovering gold, copper, and cobalt from discarded circuit boards, urban mining offers a way to secure critical resources while reducing the environmental destruction caused by conventional mining.

Despite its economic potential, the process of urban mining is currently hindered by the complex design of modern devices, which are often not built for easy disassembly. Recovering high-purity materials from microscopic components requires sophisticated chemical processes that can be energy-intensive if not managed correctly. Furthermore, the global recycling rate for e-waste remains remarkably low due to a lack of specialized infrastructure and consumer awareness in many regions. Ultimately, the transition to a sustainable digital economy requires a shift toward modular product design and the international scaling of recycling technologies to close the loop on material lifecycles.
