DuPont and Toyota have confirmed the feasibility of a technology they have developed to recycle and reuse Nylon 6 (polyamide 6) from automotive intake manifolds.
The technology/process is called DuPont Composite Recycle Technology. It produces nylon that is the equivalent to virgin material. When tested alongside virgin material, the recycled material was within specification for intake manifold applications.
The technology will help reduce impact on the environment from waste generated by the automotive industry. European Union directives have called for 85% of a vehicle to be able to be recovered or reused. Currently about 75 to 80% can be recycled.
The new process will not only reduce the amount of waste generated by end-of-life vehicles, but it all also reduce the amount of CO2 and emissions as less energy is required to recycle existing material, compared to producing virgin material.
While the technology is suited top nylon 6, it is also applicable to nylon 66 and can be used to produce nylon resin of any desired molecular weight.
