A multitude of metals can be recycled without losing their original properties. Currently, the number of recycled metals and their alloys are recognized as the key driver in boosting recycling activities. In fact, nickel, nickel-titanium alloy, and other nickel alloy recycling have been utilized as an indicator of the environmental performance of businesses. However, this method of considering the recyclability of metal has been seen to facilitate inefficiency in both the use and production of those recycled metals. This is for the reason that the recycled content approach misses to consider the environmental costs and the benefits associated with attaining the goal of sustainability.
A good alternative for nickel and nickel-titanium alloy recycling is the life cycle approach which offers a more efficient and accurate way as it takes into account the material flows at the end of the product life. Therefore, it presents a better assessment of both the economic and environmental assumptions with the aim of increasing recycling activities. This allows decision-makers to identify inefficiencies and any related environmental impacts of recycling and thus improve product recovery and material recyclability.
The life cycle approach is widely adopted in a circular economy in which resources, emissions, and even energy leaks are reduced by slowing down and narrowing the energy and material loops. All of these goals are being accomplished in several facets of nickel, nickel-titanium alloy, and nickel alloy recycling. This recycling approach begins from having the right design and proper maintenance to repair, reuse, refurbishing, or remanufacturing until the last stage of recycling. It is a much better framework than a linear economy where production is considered only on three things - take, make, and dispose of.
The high recyclability and other amazing properties of nickel and its alloys are ideal in demonstrating how they perfectly satisfy the circular economy approach. Nickel improves the resistance of the material to corrosion as well as makes it longer-lasting with less maintenance. Moreover, its high value makes the material and its recycling very attractive, allowing nickel to re-enter the economy even after the life of nickel-containing products has ceased.
