Recycling and Melt-Blown Forming of Polylactic Acid KN95 Mask Scraps

Key Points

• The recycling process improves the biodegradability of polylactic acid masks and reduces environmental waste.
• Recycling velocity was assessed using melt-blown forming techniques alongside standard material tests.
• Analysis of processed scrap shows the potential to repurpose materials into functional products after recycling.
• Findings support ongoing efforts to reduce single-use plastics in medical and industrial applications.
