Evergreen Nylon Recycling

Evergreen Nylon Recycling, a DSM/AlliedSignal joint venture, opened in November 1999. The plant will eonvert over 90,000 t/y of nylon 6 earpet waste into the raw material for nylon, caprolaetam. At the moment 450,000 tonnes of nylon 6 earpet waste is transported to US landfills each year. A fifth of this will be reeyeled in the new plant. The 45,000 tonnes of eaprolaetam that Evergreen Nylon Reeyeling will produee every year ean be used to make nylon 6 of the same quality and with the same properties as virgin nylon 6.

This fall, the closed-loop Evergreen Nylon Recycling plant will start up in the US, a joint venture of DSM Chemicals North America and AlliedSignal. The facility will recover 45,000 m.t./year of caprolactam by depolymerising the fibres from 100,000 m.t./year of discarded nylon-6 carpets. Meanwhile in Germany, Lurgi is building the Polyamid 2000 AG facility. It will process 120,000 m.t./year of carpet waste and recover 10,000 m.t./ year of caprolactam from nylon-6 carpets and 13,000 m.t./ year of nylon-6-6 from nylon-6-6 carpets. 

In August, 2001 production at the Evergreen Nylon Recycling plant was suspended indefinitely. Higher than expected production costs combined with poor business conditions for caprolactam led the decision to suspend operations. The plant had been operating at about 60% of its capacity, and the venture determine that further capital investment will be required to improve the recycle production costs to make the plant competitive270.

Evergreen Nylon Recycling LLC, a joint venture between Honeywell International and DSM Chemicals, was in operation from 1999 to 2001. It used a two-stage selective pyrolysis process. The ground nylon carpet, without separation, was dissolved with high-pressure steam and then continuously hydrolyzed with super-heated steam to form caprolactam. With a 100 thousand tons per year capacity, the program diverted over one hundred thousand tons of post-consumer carpet from the landfill to produced virgin-quality caprolactam. - ...
