Summary Reader Response (Draft 3)
The Levy (2022) article that is posted on The University of Texas at Austin news site, titled “Plastic-eating Enzyme Could Eliminate Billions of Tons of Landfill Waste'', revealed to the readers that researchers at The University of Texas at Austin have developed an enzyme variant that can accelerate the degradation of environmentally harmful plastics in hours or days instead of centuries. The article also stated that the researchers mainly focused on polyethylene terephthalate (PET), a polymer most commonly found in consumer packaging and certain fibers and textiles. This enzyme variant is able to disintegrate the plastic into smaller parts (depolymerization) and then put it back together (repolymerization) which begins the upcycling process. Lavars (2022) mentioned that plastic-eating enzymes were first created in 2016, and among the factors that have hindered the application of this plastic-eating enzyme are its inability to function at low temperatures and different pH rang...
