Nickel in a circular economy. The concept of a circular economy is generally understood to be "a regenerative system in which resource input and waste, emission, and energy leakage are minimised by slowing, closing, and narrowing energy and material loops.This can be achieved through long lasting design, maintenance, repair, reuse, remanufacturing, refurbishing, and recycling 1.
One of the many benefits of this progress is the reduction of waste and dangerous chemicals. Although nickel is documented being used as far back as 3500 BC by Syrians who used a small amount and in 235 BC by the Chinese who minted coins from nickel, nickel mining itself is relatively new compared to other mined materials.

Mining produces large amounts of waste. In Sweden, the mining industry accounts for over 80 percent of the country’s total waste production each year. While the amount of waste can be substantial, not all waste is considered harmful to the environment. Some waste might even be safe to use in other applications, such as in building materials.
Mining in developing countries remains controversial since a huge impact on the cultural climate, the physical environs and the socio-economic status of the local people can result (Encarta 2001). Mining operations and their mining waste disposal methods are considered one of the main sources of environmental degradation.
