Recycling mining waste – A new business? (Long version)

Summary

The NEMO project in Europe addresses the issue of 600 million tons of mining waste annually by recovering valuable metals like rare earths, cobalt, and nickel from tailings. This not only supports a greener society but also transforms the remaining minerals into sustainable building products, reducing CO2 emissions by up to 70%. The project aims to replace cement in concrete with tailings, offering an eco-friendly and cost-effective solution for local building material needs.
