The developing research into microplastics shows that the need to find ways to remove them are urgent. Through the modification of ligno-cellulosic frameworks with polyphenol coatings to create a filter, polyethylene can be captured. This novel filter was developed using a wet packing method and a commercial fish pump to move the plastics from the Milli-Q solution to the filter. Through π-π, electrostatic, and physical interactions, pristine and degraded polyethylene was removed from a microplastic solution being pumped through the filter. This filter provides a look at how an organic waste, such as wood, can be utilized to remove contaminants and used in commercial settings, such as wastewater treatment facilities.
