DSM, AlliedSignal roll out carpet recycling strategy

Chemical manufacturers DSM and AlliedSignal are to build a recycling plant in the USA for carpet made from nylon 6.

The US project appears to place rival carpet fibre producer DuPont at a marketing disadvantage because its carpet fibre, nylon 6.6, is proving harder to depolymerise.
