The so-called new technology which is to be applied here does not refer to the method itself. Theoretically, extraction technologies in combination with polymers have already been considered and already applied. I suppose - this is only my opinion and a guess - "the new" is the extraction machine itself in combination with Molecularly Imprinted Polymers. This will be the reason for the secret-mongering. The fact is that in the food industry polymers have been used for some time now for removing specific agrochemicals. This is nothing new. http://www.ligarpolymers.com/index.php/our-polymers/ https://en.wikipedia.org/wiki/Molecularly_imprinted_polymer
