摘要

Cocona Labs reports that it can incorporate an additive into its thermoregulating fibres and yarns (called 37.5) that enables them to biodegrade in landfills. In testing undertaken according to the D5511 standard(1) published by ASTM International of West Conshohocken, Pennsylvania, USA, 37.5 polyethylene terephthalate (PET) staple fibres embedded with the additive biodegraded by 78% after 726 days in an accelerated landfill environment. Cocona Labs, of Boulder, Colorado, USA, says that this data indicates that the fibres will break-down by 50-80% over the productive lifetime of the average US landfill site (80-100 years). It caveats these findings by adding that the stated rate and extent of degradation will vary by landfill and fabric type, and the material might not continue to degrade after this time. Conventional PET does not biodegrade.
