National Student Design Expo
Thanks for your question. In our next phase of experiments that is now underway, we plan to quantify how the polymer concentration and the number of paper layers used affect the strengths and dissociation properties of the ethanol-based wipes. We have also identified a few additional options for making ethanol-free versions of our wet wipes and plan to conduct further material characterization to test these approaches. Finally, to ensure that (once the biopolymer binder dissolves) the wet wipe degradation products are not disruptive to the wastewater treatment process, we will use microbiological techniques to analyze how they affect microbial concentration and activity in wastewater bioreactors.
That sounds awesome! I hope we're able to phase out current wet wipes in favor of a design like yours!
Thank you! We are excited about this project and are grateful for the EPA’s support.
