Troy University Center for Materials & Manufacturing Sciences Advances Sustainable PPE Materials Research

In response to the ongoing COVID‑19 pandemic, Troy University’s Center for Materials and Manufacturing Sciences in Troy, Alabama, has launched cutting‑edge research aimed at expanding the production of personal protective equipment (PPE) for healthcare workers and establishing innovative pathways for recycling medical plastic waste.

Director Dr. Govind Menon explained that the center is exploring new polymer‑based manufacturing techniques to increase PPE output and better prepare for future public‑health challenges. One key focus is the use of high‑density polyethylene (HDPE) derived from natural milk‑jug material as a substitute for the polyethylene (PE) and polypropylene (PP) typically used in masks and gowns. Because natural HDPE contains no additives, it simplifies decontamination and helps shift the perception that recycled plastics cannot meet medical‑grade standards.

Associate Professor Dr. Zhiyong Wang, who serves as assistant director of the center, leads polymer research in one of Troy’s state‑of‑the‑art laboratories. His work focuses on developing advanced polymeric materials for medical applications.

In addition to PPE development, the center is tackling the pressing issue of medical plastic waste. U.S. healthcare facilities generate more than 14,000 tons of medical waste daily, with up to 25% consisting of plastic packaging and products. At present, most of this plastic ends up in landfills or incinerators. The center’s researchers are investigating feasible recycling methods to repurpose uncontaminated packaging for non‑medical uses, thereby reducing environmental impact.

“We are particularly interested in the significant volume of unopened, uncontaminated packaging discarded during surgical procedures,” Menon said. “By processing these materials at high temperatures—typically between 200 °C and 250 °C—we can effectively eliminate biological contaminants. We’ll collaborate closely with the Biology Department to ensure safety and compliance as we advance these initiatives,” he added. The team also plans to explore next‑generation smart polymeric materials and additives for future protective gear.

Founded in 2018 with support from the National Institute of Standards and Technology (NIST), Troy University’s Center for Materials and Manufacturing Sciences is a fully integrated, multidisciplinary research facility dedicated to polymer science and recycling innovation.
