Growing demand for sustainable products from consumers, governments and NGOs has made the use of recycled materials in fashion such as recycled polyester (rPET) tremendously valuable to brands as well as the environment. But today, there are some challenges related to the use of rPET, such as:

rPET more expensive than virgin PET

(up to 50%)

Lack of reliable
proofs

Greenwashing

INNOVATIVE SUSTAINABLE SCIENCE:
Recycled polyester testing – verification & quantification

18 months research
BEST solution to determine IPA presence NMR (Nuclear Magnetic Resonance) that detects the presence of isophthalic acid [IPA] which is under patent

What are the benefits of this method?

Certainty
