Transforming Plastic Waste
Researchers have developed a method to use bacteria to convert common plastic waste into biodegradable spider silk. This process utilizes the bacteria Pseudomonas aeruginosa, which consumes polyethylene, a prevalent component of plastics. The plastic is first broken down into a waxy substance, making it easier for the bacteria to process it into a substance resembling cotton puffs. This breakthrough not only offers a potential solution to the global plastic crisis but also redefines plastic as a resource for producing valuable and sustainable materials.
