This a fabulous concept – replacing micro plastics with silk!
By controlling the process of making the liquid silk, silk molecules can be created in different sizes to perform different functions.
“The acids and the enzymes in our digestive system can easily degrade silk, whereas the enzymes are not tailored to breaking down non-protein entities such as a synthetic plastic,” Altman says. Similarly, bacteria can easily degrade silk if it’s composted, and if a product made with liquid silk entered the ocean, fish and plankton could safely digest it.
