Challenges in Metal Recycling

In principle, metals are actually infinitely recyclable. Metal recycling involves the recovery and processing of scrap metal so that it can be introduced again as a raw material. There are some challenges in metal recycling. This is because of the limits imposed upon it like thermodynamics of separation, recycling technologies, product designing and social behaviour. Here are some of the main challenges in metal recycling.

Low Recycling Rates of Specialty Metals

There are various reasons that account for the low recycling rates of specialty metals. These metals are mainly used in small amounts in high tech designs. Because of their specialized usage along with the small quantity, they are very difficult to recycle and it is economically unjustified.

Activities Required for the Greatest Potential to Improve Metal Recycling

The main activity behind the greatest potential to recycle metals is the collection.  There is a large inconsistency between the advanced technology used in the manufacturing process and that used in the recycling process. Also, there is no feedback between the product designers and recycling material/industry scientists.

High efficiency is needed in collecting metal which avoids frustration later in the process of the life cycle of the material. But this again requires incentives and initiatives from companies and governments to make it worthwhile and also profound changes in social attitudes.

Problems for the Technology Industry 

Material prices rise without the developments in closed loop material system. Even reserves are expanded along with mining capabilities being improved and this will forever be governed by the law of diminishing returns. Eventually, the prices of these materials will increase which will result in an increase in production cost.  In other words, costs will rise in other directions.

 The most advantageous actions that can actually change improve the rates of recycling are an enhanced deployment of modern recycling technology, improved design for recycling, and increased collection rates of discarded products.
