Due to the fact that there are different types of polyamides, different methods are used to recycle each of them. For example, a new method called Econail recycling is used to recycle nylon 6. In this recycling method, threads are extracted from the nylon product that will be used in other related industries. Also, in order to recycle all kinds of plastics, especially in the food industry, first by crushing them, they create smaller pieces, and then they melt them and start producing the product again. Due to the different chemical structure of polyamides, during recycling, each type of plastic material must be recycled with its own type and melted separately because their melting point is different from each other.
