Innovative Solutions Tackle Plastic Pollution: From Bioengineered Adhesives to Self-Destructing Plastics
  • Plastic pollution poses a critical global challenge, with an estimated 22 million tonnes of plastic waste leaking into the environment in 2019, a figure projected to double by 2060.

  • Each year, approximately 20 million metric tons of plastic waste enters the world's waterways, exacerbating environmental degradation.

  • In response to this pressing issue, innovative solutions are emerging from various organizations, including academic researchers and startups.

  • Researchers at Rice University have developed a nature-inspired adhesive utilizing bioengineered microorganisms to tackle marine plastic pollution.

  • This technology enhances the adhesion of bacteria to polyethylene terephthalate (PET), a major component of plastic waste that is notoriously difficult to break down.

  • By incorporating polyethylene terephthalate hydrolases into the adhesive, researchers enable the breakdown of PET into smaller molecules through biorecycling.

  • Tests have shown a remarkable 400-fold improvement in the bacteria's ability to cling to plastic at 37 degrees Celsius, leading to significant degradation of plastics overnight.

  • In another innovative approach, E.V.A Biosystems, a startup from the University of Edinburgh, has created a 'smart' plastic that self-destructs in water without producing harmful microplastics.

  • Dr. Alexander Speakman, founder of E.V.A, highlights that their technology enhances existing plastics, allowing them to decompose inappropriately discarded locations.

  • E.V.A's innovation earned recognition by winning the top prize in the Net Zero category at the Converge Awards, along with a cash prize of £30,000 and additional business-development support.

  • Additionally, an adhesive inspired by the stickiness of mussels, which uses a naturally occurring amino acid called 3,4-dihydroxyphenylalanine (DOPA), has been developed to prevent biofouling on various surfaces.

  • This mussel-inspired adhesive could protect underwater structures, such as pipes and ship hulls, from the accumulation of algae and barnacles, enhancing their longevity and effectiveness.
