One option for a material product’s end of life is recycling. Why is recycling of metals more successful than that of polymers? What are the additional challenges in recycling polymers compared to metals?
In metal recycling process, production cost is law then find the metal from the ore. Second things, mining components is too costly so investment is too much. As compare in recycling process processing cost is law then the mining the metal from the ore.
Other side Plastic is produce by chemical process so Production cost of plastic is law as compare to find the new metal from the core and recycling the plastic. For plastic recycling first need to collect the plastic and then clean it after the cleaning. Then it is classified in different group because there are too much type of plastic available. So for plastic it is complicated process to recycling the plastic again and again.
So conclusion is in metal recycling process we can decrees the cost of the metal. Plastic recycling process is costly then to produce new plastic. So, recycling of metal is more successful then plastic recycling.
Additional challenges:
Toxic gases are produce during the recycling of plastic is major problem for environment. As compare to plastic recycling process, in metal recycling process law toxic gases produce. There are additional issues associated with variations in the quantity and quality of supply compared with virgin (New) plastics. Quality of virgin (New) plastic is too good then recycle plastic. Effective recycling of mixed plastics waste is the next major challenge for the plastics recycling sector. One of the other problem is demand and supply of the plastic in the market. Production of the plastic by using recycling is not enough for the demand of plastic in the market. There is need to classify the plastic during the recycle is time consumer process for production line for recycling process and it is also important to get good plastic at end of the recycling process. Also there are many type of the polymer in waste plastic so it is difficult to identify the type of the polymer.
