Your 'recycled polyester' leggings are not as sustainable as you think

Recycled polyester activewear and swimwear are now everywhere. Major global brands sell leggings, swimsuits and puffer jackets with labels that claim they're "made from recycled plastic bottles." Millions of people buy these products believing they're making a more sustainable choice.

I just found this photo of one of the most disgusting preparations of my entire training… PU foam!

First, a highly branched polyester was synthesized from adipic acid, oleic acid, and phthalic anhydride with 1,1,1-tris(hydroxymethyl)propane using PTSA as an acid catalyst. The polycondensation ran for many hours at ~190 °C under nitrogen and vacuum while water was continuously removed as a by-product.

During the reaction, the acid number (determined by titration, mg KOH/g) was monitored until it dropped below 10, with a target around 5. The resulting viscous polyester polyol was then reacted with tolylene-2,4-diisocyanate to produce rigid polyurethane foam.

Chemically interesting.
Visually and olfactorily… slightly traumatic. 🧪😵

#Mikroplastik wurde in fast allen untersuchten Geweben von #Meeresschildkröten entdeckt, sogar im männlichen #Fortpflanzungssystem.

In 98,8 % der Proben fanden Forschende Fremdpartikel, meist #Mikroplastik aus #Polypropylen, #Polyester und #Polyethylen. Die winzigen Teilchen könnten #Entzündungen, #Organschäden und Probleme bei der #Fortpflanzung verursachen.
