Researchers at RPI published a paper in Microbial Cell Factories outlining a new and novel method of creating spider silk protein from waste plastics.
This project used a new strain of Pseudomonas bacteria capable of converting depolymerized polyethylene into targeted recombinant proteins. While this work is in the early stages, it shows the potential for this process to create spider silk-like proteins from partially decomposed plastics.
Plastic wastes continue to accumulate globally, resulting in disposal and recycling challenges as well as increased levels of microplastics showing up in our food and water supplies. Creating useful and easily biodegradable silk proteins from these materials could help alleviate this growing concern.
"I am encouraged to see the continued focus and breadth of research developing in the field of spider silk technologies," said CEO and Founder,
