Not enough information here to really pass judgement, but multiple issues to consider: 1) 40C is easily the temperature products will see on a tarmac in Arizona while being shipped cross country. Unless they are working with enzymes with a higher temperature range, this would essentially require a cold chain and limit end-use environments which would be a nonstarter for most manufacturers/products. 2) Most plastics are melt processed (extruded/injection molded) at temperatures high enough to denature enzymes/proteins, I do not see an indication that they are working with a heat stable enzyme, which suggests they are relying on manufacturing methods that are likely to be less economically viable. 3) Enzymes are expensive! Unless they are working with (or are plausibly developing) a cost effective solution, I wouldn't be surprised if their material is orders of magnitude more expensive than commodity packaging plastics.
