The global market for PU was valued at over USD 45 billion in 2020. The main drawback is however that they are made using hazardous isocyanate, which entails strict safety procedures during their manufacture and risk of leakage during their use.
Elevated levels of such chemicals in humans are a cause of several serious ailments such as depression, breast and prostate cancer, asthma, obesity, etc. The other problem is that the current PUs are non-recyclable.
We have developed an alternative patented route for producing non-isocyanate thermoplastic polyurethanes that are biobased and recyclable, and hence suited for circular economy.
