Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
Nylon is a robust polymer and lends itself well to recycling. Much nylon resin is recycled directly in a closed loop at the injection molding machine, by grinding sprues and runners and mixing them with the virgin granules being consumed by the molding machine.
Econyl regenerated nylon is a material and a brand introduced in 2011 by Aquafil. [1] It is made entirely from waste otherwise polluting the Earth, such as industrial discards, fabric scraps from clothing manufacturing companies, [2] old carpets and fishing nets (mainly from the aquaculture industry).

The preferred method for recycling this stream is mechanical recycle, a process in which the resin is remelted, filtered and extruded or molded into new PET articles, such as bottles, [2] films [13] strapping or fibers. [14] If the PET feedstock is not pure enough for mechanical recycle, then chemical recycling back to monomers or oligomers is ...
