American Fibers & Yarns (AF&Y) says it can prove the greenness of its polypropylene yarns with its cradle to cradle product certification awarded by consulting firm MBDC (McDonough Braungart Design Chemistry). The MBDC evaluation includes analysis of resin, pigment and additive concentrate formulations, as well as all finish ingredients.
MBDC rates each ingredient green, yellow or red based on their impact to human and environmental health. Green or yellow are considered “approved.”[
AF&Y says some of their pigments such as yellows and oranges intended for high UV applications do contain heavy metals. Ingredients that did not qualify for the certification will be phased out eventually as soon as new alternatives will be available.
Third party certification is certainly a good way to prove to their customers that they are not greenwashers.
