Did you know that one tonne of discarded smartphones contains approximately 100 times more gold than one tonne of high-grade virgin gold ore? This reality underscores the immense economic potential of responsible urban mining.
Beyond Landfill Diversion: Supply Chain Independence
Electronic devices power modern civilization, yet manufacturing them requires dozens of finite materials: gold for oxidation-free contact pins, silver for soldered traces, copper for inductive coils, and palladium for multi-layer ceramic capacitors (MLCCs).
When devices reach their end-of-life, sending them to landfills wastes irreplaceable natural capital. Conversely, responsible urban mining reduces global primary mining energy consumption by over 80%, avoiding millions of tonnes of CO2 emissions.
Zero-Emission Hydrometallurgy
Traditional informal recycling relies on dangerous acid cyanide baths and open-flame torching, releasing toxic dioxins, furans, and nitrogen dioxide fumes.
At Shree Alliance, our automated dismantling lines segregate circuit boards with millimetric accuracy. We use safe, closed-loop hydrometallurgical precipitation and electro-winning that yields 99.9% pure electrolytic copper cathodes and gold sponge, with zero hazardous atmospheric emissions and complete water recycling.
